Reflection on the teaching plan of addition and subtract mixed operation within 10 years of the big class
The following are some of the key points to reflect on the teaching plan for the addition and subtract operations within the first ten classes: ** 1. Achievement of teaching objectives ** 1. ** Calculating ability ** - During the teaching process, the children gradually mastered the method of adding and deducting mixed operations within 10, which indicated that the teaching had a certain effect in imparting knowledge. However, it was necessary to consider whether every child could perform calculations skillfully and accurately, and whether some children had a vague understanding of certain operation sequences (such as adding and then deducting or deducting and then adding). 2. ** Ability Cultivation ** - Through group operations and other activities, the children developed a sense of teamwork and cooperation, which was a positive result of the teaching process. However, they also had to consider whether every child could fully play their role in the cooperation. Were there any children who were sidelined due to differences in personality or ability, which would affect their absorption of mathematical knowledge? - From the perspective of improving children's ability to use mathematical calculations, it was necessary to consider whether there were enough real-life scenarios to integrate into the teaching, so that children could truly understand the application of mathematical calculations in life, not just the calculation of questions. ** 2. Teaching methods ** 1. ** Interactive teaching ** - The use of a staged and interacting teaching method was an effective method. Through demonstration and examples to explain the operation and calculation methods of the knowledge points, the children can practice and consolidate in Mini games or activities. However, it was necessary to reflect on whether the design of Mini games or activities was interesting and challenging enough to continue to attract the attention of young children. For example, whether some children lost interest because the game was too difficult or too low. 2. ** Language output guidance ** - Although the guidance of language output could enhance children's interest in learning to a certain extent, it might be necessary to further improve the liveliness of the language. Children's thinking was more intuitive, and more vivid language helped them better understand mathematical concepts. For example, when explaining the order of operations, one could use more metaphor or story-like descriptions instead of purely explaining the rules. ** 3. Teaching preparation ** 1. ** Teaching aid usage ** - If you use teaching aids such as ten cards, numbered cards, small target cards, whiteboards, etc., you have to consider whether the use of the teaching aids has fully utilized its functions. For example, whether the number card was only used to display numbers, and whether there was a better way to interact with the number card, such as letting the child combine the cards to perform the addition, addition, and blending operations. - Whether the choice of teaching aids is suitable for the age of the child, and whether there are teaching aids that can be improved or replaced to better promote the child's understanding of the addition and addition of mixed operations within 10. ** 4. Teaching process ** 1. ** Introduction Stage ** - Singing, dancing, Mini games, and other methods to warm up the body and brain of the child could stimulate the child's enthusiasm for learning. However, it was necessary to reflect on whether the introduction was closely related to the formal teaching content. For example, whether the addition and reduction operations in the song were too simple or complicated, and whether it could accurately guide the child into the subsequent learning state. - It was effective to use props to attract children's attention, but one had to consider whether the use of props had a continuous guiding effect or only had a temporary eye-catching effect. 2. ** Consolidating Stage ** - During the practice session, one had to consider whether the amount of practice was enough and whether it covered various types of addition and deduction operations within 10 (such as different number combinations, different operation orders, etc.). At the same time, whether there was sufficient targeted guidance for the mistakes made by the children in the reinforcement exercises to help the children completely understand the reasons for the mistakes and correct them.

Teaching plan and reflection on the mixed operation of rational number addition and substitution
The following is a teaching plan for the mixed addition and deduction of rational numbers and an example of reflection: ** 1. Teaching objectives ** 1. Let the students master the rules of addition and deduction of rational numbers. 2. Cultivate the students 'ability to calculate accurately and simplify the calculation using the calculation law. 3. To improve the students 'ability to solve the practical problems of addition and deduction of rational numbers. ** 2. Important and Difficult Points in Teaching ** 1. ** Main point ** - Master the order and rules of addition and deduction of rational numbers. - Learn to use the commutative law of addition and the association law to simplify operations. 2. ** Difficulty ** - Accurately handle the symbols in the calculation. - He could flexibly use the operation law to perform simple calculations. ** 3. Teaching process ** #(I) Knowledge Review 1. Review the addition rule of rational numbers: - Add two numbers with the same sign, take the same sign, and add the absolute value. - When two numbers with different signs are added together, the sum is 0 when the absolute values are equal; when the absolute values are not equal, the sign of the number with the larger absolute value is taken, and the smaller absolute value is deducted from the larger absolute value. - If a number was added to 0, it would still be this number. 2. Review the rational number substitution rule: Subtracting a number is equal to adding the opposite number. #(II) New lesson teaching 1. Introduction of rational numbers, addition and substitution, mixed operations - Give a few formulas for addition and substitution of rational numbers, such as <3+(-2)-5>,<-1 - (-3)+2>, etc., to guide the students to think about how to calculate according to the order. - The order of calculation was emphasized: from left to right. 2. Using operational laws to simplify operations - Explain the application of the commutative law of addition, a + b=b + a, and the association law, a + b +c=a+ b + c, in the mixed operation of addition and substitution of rational numbers. - For example, for the formula "2 - 3+5 - 7", you can combine positive numbers with positive numbers and negative numbers with negative numbers, which is "(2 + 5)+(-3 - 7)", and then calculate them separately. #(3) Class Practice 1. Arrange some exercises on rational addition and deduction, such as: - \(4 - 7+3 - 5\) - \(-2+5 - 8+3\) - <3.5 - 2.5+1.5 - 4.5>(Including the operation of decimals to let students understand the concept of rational numbers including decimals and fraction) 2. Inspecting the students 'practice and correcting the mistakes that the students made during the calculation process, especially the symbols. #(IV) Class summary 1. Recalling the order and rules of addition and substitution of rational numbers. 2. It emphasized the importance and methods of using operational laws to simplify operations. #(5) Homework 1. Arrange an appropriate amount of homework, including some basic rational number addition and deduction mixed operation questions and questions that need to use the operation law to simplify the operation. ** 4. Reflection on Teaching ** 1. the key of success - Through the knowledge review session, it effectively helped the students consolidate the basic rules of addition and deduction of rational numbers, laying a good foundation for the study of mixed operations. - In the course of the new lesson, he explained the application of the operation order and operation law with specific formulas. It was more intuitive and most students could understand and master it. - The classroom practice session could find the students 'problems in time, such as symbol processing errors, and correct them accordingly. 2. deficiencies in - For some students with learning difficulties, it was still difficult to use the operational law to simplify operations. They might need more one-on-one tutoring or more basic exercises. - In the teaching process, there were few examples of the application of rational addition and deduction in real life, which was not conducive for students to understand the practical significance of the operation. This part of the content could be added in the subsequent teaching. - The pace of the class could be further optimized to give students more time to think and discuss on their own to increase student participation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reflection on the teaching of addition table within 20
There were some problems with the traditional teaching method in addition table teaching. For example, if the teacher directly showed the sorted addition table and asked the students to find the rules and fill in the missing formulas, the process would be boring and the students would be easily distracted. An improved teaching method was to first ask the students which addition formulas within 20 had been learned, and then let the students think about how to classify the formulas, such as sorting them according to numbers or sorting them according to the type of addition. Then, according to the classification method proposed by the students (such as dividing 9 plus a few into one class, etc.), the teacher made the calculations into cards in advance, stuck magnetic nails on the back and gave them to the students, and asked the students to stick the cards on the blackboard for sorting. In this process, the students could discover the rules of the addition table arrangement on their own and cultivate the ability to explore and discover on their own. Moreover, the students were interested and focused. When looking for the law of slanting, by changing the way of asking questions, such as "find the formula that gets 11", the students could find the law of slanting arrangement in the process of finding the formula, and finally fill in the missing formula in the addition table. In addition, in the teaching of the addition formula within 20, the traditional memorization method started from the first column and read in the conventional way. There were problems that were difficult to memorize, remember, and apply. The new reading method started from the big numbers, such as 9 + 2 = 11, which was read as nine and twenty-one, and some of the pithy formulas were integrated with the multiplication formula. The teaching could be divided into two steps. First, the students would read vertically and use it, and then read horizontally (from right to left). Students who had the ability to learn could learn this reading method, and this reading method would also be helpful for learning to abdicate and subtract within 20 in the next semester. At the same time, in the teaching process, attention should also be paid to the classroom organization, to pay attention to students 'independent learning and the opening of the classroom, to pay attention to students' learning, to avoid simple knowledge instilling, to ensure that the teaching focus is highlighted, such as the addition and substitution table rules in the review class within 20 (the numbers behind the minus sign are the same when looking vertically, the numbers in front of the minus sign are the same when looking horizontally, and the numbers are the same when looking diagonally). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Big class mathematics within 10 addition open class teaching plan
The following is a teaching plan for a large class of mathematics within 10: * * 1. Teaching objectives ** 1. Let the child skillfully use addition within 10 and understand that the same answer can correspond to multiple questions. 2. Familiarize the child with some important phone numbers in life and stimulate his interest in understanding how to contact his peers. * * 2. Important and Difficult Points in Teaching ** 1. * * Main point ** - Proficient in addition operations within 10. - He was familiar with the important phone numbers in his life. 2. * * Difficulty ** - Understand the concept that one answer can correspond to multiple questions. * * 3. Teaching preparation ** 1. 10 plus and minus question cards, deciphering phone number practice paper, phone number cards composed of addition and subtract questions, red flags, yellow flags, blue flags, green flags, scoreboard. 2. Based on the fact that the children had carried out the theme activity of "I'm going to elementary school", the children had the desire to know how to contact their peers. * * 4. Teaching process ** #(I) Introduction: Review addition within 10 1. Lead the conversation - Teacher: The children are about to graduate. Before this, everyone mentioned the contact methods after breaking up, such as writing letters, sending cards, visiting, calling, etc. Today, we'll play a game of deciphering phone numbers. 2. Deciphering a phone number - The teacher showed a number card consisting of eight addition and substitution questions, such as 3 + 3, 7 - 4, 8 + 1, etc. - The teacher asked questions from many aspects. For example, what was the first number on this phone? What number was "6"? What was the last person? - After the child deciphered the phone number, the teacher asked,"How did you do it?" He guided the child to answer by adding and deducting. The teacher then asked the child if he knew whose number it was (for example, guiding the child to answer that it was the kindergarten) and told the child that he could call this number if he missed the teacher or had something to do. 3. Mental Arithmetic, Deciphering the Phone Number - The teacher showed the second phone password and asked the child to calculate in his mind, remember the answer in his heart, and then say the answer together later. - The teacher showed the third phone password and asked the child to quickly and accurately decipher the phone password. #(2) Learning Part: Set a password for a phone number and crack it 1. calculate the answer according to the formula - The children were divided into four teams, red, green, yellow, and blue. Each team had 10 phone passwords. They would carry out activities in the form of group competitions to compare which team could decipher the phone number quickly and accurately. - Each group would exchange checks, and then each group would send a representative to report the other's score. 2. Try to make up questions according to the answers - Teachers first provide special numbers with fewer numbers (such as 110, 119, 120) for children to write questions. For example, for "119", it could be compiled into a set of passwords: 4 - 3, 7 - 6, 2 + 7, or 7 - 5 + 2 - 3, 5 - 2 - 2, 1 + 5 + 3, etc., so that the child could understand that one answer could correspond to multiple questions. - The children were divided into groups to try to make up the questions. The groups exchanged questions and cracked them. Finally, the phone number that was cracked and the same number as the number on the blackboard was pasted on the blackboard. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Countdown teaching plan and reflection of the number within 10
The following is a lesson plan for counting backwards from 10: ** 1. Activity Target ** 1. Guide the child to learn the numbers from 1 to 10. 2. During the game, one could sense the order of the countdown. ** 2. Important and Difficult Points of the Activity ** 1. ** Main point ** - Understand the law of the number 1 - 10. 2. ** Difficulty ** - Master the concept of countdown and be able to use it skillfully. ** 3. Event preparation ** 1. Two sets of 1 - 10 numbered cards and two directional arrows. 2. There were a few magnetic dots and ten small animal toys. 3. Two small cars (different colors). 4. Music: "Outings." ** 4. Activity process ** 1. ** Beginning ** - The teacher introduced the topic through conversation, such as going on an outing, to attract the child's attention and interest in participating in the activity. 2. ** Basics ** - ** Understanding the number ** - The method of guiding children to report numbers is to first perceive the law of the number, that is, according to the order from small to large, the latter number is one more than the previous number, such a row of numbers is called a number. - ** Understanding the countdown ** - The teacher guided the child's perception. Due to the change in position, the order of the numbers would also change. From large numbers to decimals, the latter number was one less than the previous number. The row of numbers arranged in this way was called the countdown. 3. ** Consolidating Part ** - The teacher used small animal toys. Some small animals had numbers on their chests, while others did not. The children helped them line up according to the rules. - The children played games with the small animals. In the form of games, they guided the children to practice counting from any number. - The teacher introduced the car in the context of an outing and guided the children to observe the different colors of the car. They also sensed that due to the change in orientation, the order of the numbers would also change. The children were allowed to participate in the experience and consolidate their perception of the forward and backward numbers. - Guide the child to participate in the finger game and practice counting down again. 4. ** End ** - Guide the child to recall where there are forward and backward numbers in life to enrich the child's life experience. ** 5. Event Extension ** Children, please go home and search for the forward and backward numbers with your friends or parents. Let's share it in the next section. ** Teaching Reflection **: 1. ** The effectiveness of teaching methods ** - Through a variety of games to teach, such as the use of small animal toys, cars, finger games, etc., so that children in a relaxed and happy atmosphere to learn counting down and counting down, this method is more in line with the learning characteristics of children, can effectively attract children's attention and stimulate their interest in learning. 2. ** Children's learning effect ** - Most children could understand the concept of counting down and counting down, and could perform simple counting down and counting down operations in the game. However, there are still a few children who have difficulty counting down from any number and may need more individual guidance in subsequent activities. 3. ** Directions to improve the event ** - In the teaching process, more interaction sessions could be added to encourage children to discover the application of forward and backward numbers in life, instead of just being guided by the teacher to recall. At the same time, the difficulty of the game could be adjusted so that every child could develop fully within their own abilities. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reflection on the teaching plan of mathematics demonstration within 10 years of middle class
The following is an example of a reflection on the mathematics demonstration lesson plan for the middle class: ** 1. Achievement of teaching objectives ** 1. ** Knowledge and Skill Target ** - In the teaching of counting within 10, if the goal was to let the child accurately count the number of items within 10, from the activity design of the lesson plan, such as through the bubble classification, snowflakes and other activities, the child had more opportunities to count and calculate the number. However, in actual teaching, there might be some cases where children could not fully grasp the accurate calculation. For example, in a group activity, when making a bracelet, the number of points for 10 beads of different sizes may interfere with the children due to the difference in the size of the beads, causing some children to make mistakes. - If the teaching goal also involved the conservation of perceptual numbers, although the bubble performance team and other situations were created to let the children feel that the number of items did not change with certain factors, there might not be enough time for the children to fully explore and understand during the teaching process. For example, when a child classified and counted bubbles in different ways, they might just mechanically follow the teacher's guidance to complete the operation. They did not really understand the nature of number conservation, and could not transfer the knowledge well in the subsequent independent operation. 2. ** Course, Method, and Target ** - The teaching plan designed a variety of activities, such as operating learning tools, group activities, etc., aimed at cultivating children's hands-on operation ability and cooperation ability. However, in actual teaching, group activities may not be organized in an orderly manner, which affects the effective cultivation of children's cooperative ability. For example, in the group activity of making costumes, when children used colorful beads to form a dragon, some children might not know how to cooperate because the rules were not clear enough, or some children might lead the activity while other children's participation was low. - The goal of letting children try different sorting methods might not fully stimulate the children's innovative thinking during the operation process. Although the teacher guided the children to arrange the snowflakes in different ways, if they did not give enough affirmation and guidance in the evaluation stage, the children might not dare to try more unique arrangements. 3. ** Emotions, attitudes, values, goals ** - In terms of building children's self-confidence and creativity, the activity design in the lesson plan gave them a certain opportunity. However, in actual teaching, if the teacher's performance and evaluation of the child's results were not timely and positive enough, it might affect the establishment of the child's self-confidence. For example, if the teacher did not give sufficient affirmation and encouragement when the child showed the results of the snowflake arrangement, the child might feel that his efforts were not recognized, thus affecting the development of self-confidence. ** 2. Teaching content ** 1. ** Selection of content ** - Choosing numbers within 10 to teach was in line with the middle class children's mathematical cognitive level. However, there might be some problems with the difficulty level of the teaching content. For example, in the teaching content of conservation of numbers, it might be more difficult for some children with weaker comprehension ability. Teachers could consider layering the content and provide simpler examples or more guiding steps. - In terms of combining the practical aspects of life, although there were some life-related situations in the lesson plan, such as bubble performance team, making bracelets, etc., it could further strengthen the connection with life. For example, he could add more application scenarios in daily life, such as distributing cutlery and fruits, so that children could more intuitively feel the omnipresence of mathematics in their lives. 2. ** Organization of content ** - The whole teaching content was organized in a logical order from simple to deep, from preparatory activities to group activities, group activities to communication summary. However, the transition between the various links might not be smooth enough. For example, the transition from the situation of the bubble performance team to the activity of putting together snowflakes may not guide the child to connect the concepts of numbers between the two, resulting in some difficulties in the conversion of thoughts. ** 3. Teaching methods ** 1. ** Situation Teaching Method ** - The teaching plan used the situation teaching method, such as the situation creation of the bubble performance team. This method could attract children's attention and stimulate their interest in learning. However, there were still some shortcomings in the continuity and depth of the situation. For example, in the entire teaching process, the situation of the bubble performance team was only used in part of the links, not throughout, so the effect of the situation was not fully exerted. 2. ** Operation Method ** - The operation method was widely used in teaching, such as letting children operate bubble cards and snowflakes. This would help young children understand mathematical concepts through personal experience. However, during the operation, the teacher's guidance might not be detailed enough. For example, when a child made a bracelet, the teacher might not give enough demonstration and guidance on how to accurately count 10 beads and wear them into a bracelet, causing some children to have difficulty operating it. 3. ** Game Teaching Method ** - Teaching methods such as drumming games could increase the fun of teaching. However, there may be some limitations in the design of the game. For example, the drumming game was not clear enough to distinguish between children's auditory perception and action perception, which may lead to children's inaccurate understanding of quantity during the game. ** 4. Teaching Resources ** 1. ** Teaching aid preparation ** - The choice of teaching materials such as bubble cards, number puzzles, snowflakes, and beads with holes was more appropriate. They could intuitively present numbers within 10. However, the variety of teaching materials could be further improved. For example, he could add some digital models, digital puzzles, and other teaching aids to let children understand the numbers within 10 from different angles. - There might be some wastage in the use of teaching materials. For example, some teaching aids might only be used once during the teaching process, and they might not be able to fully utilize their various functions. 2. ** Creation of environment ** - The teaching plan did not explicitly mention the auxiliary effect of environment creation on teaching. In actual teaching, one could create a classroom environment related to numbers within 10, such as posting number cards within 10 on the wall, pictures of physical objects corresponding to the number, etc., so that children could be constantly influenced by mathematical knowledge in their daily learning and life. ** 5. Teaching Evaluation ** 1. ** Evaluation Method ** - The evaluation method in the lesson plan was mainly based on the child's operation results and communication summary. This method allowed children to express their learning experience, but the evaluation method was relatively simple. It could increase the teacher's evaluation of the child's performance in the operation process, such as the child's operation speed, operation accuracy, cooperation ability, and so on. 2. ** Evaluation content ** - In terms of evaluation content, it mainly focused on the child's mastery of the calculation and arrangement of numbers within 10. However, there was a lack of evaluation on the changes in children's emotional attitudes during the learning process, such as whether they were more interested in mathematics activities and whether their self-confidence was enhanced. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reflection on the teaching of addition and substitution of numbers within ten thousand
The following are a few aspects that may be involved in the reflection of addition and substitution teaching: ** 1. Teaching methods ** 1. ** Diverse algorithms and independent exploration ** - It was important to give the initiative to the students when teaching addition and substitution of numbers within ten thousand, so that they could explore the calculation method independently with the help of their existing knowledge and experience. For example, for mental arithmetic and vertical calculation, don't design overly guiding questions to avoid bringing students into the default method. Let the students do the math by themselves and share the results in the group so that they can experience the success of independent learning. - In the teaching of vertical calculation, students were also allowed to try it out on their own, and then they could exchange and demonstrate. This method could effectively expand the students 'thinking and promote the exchange of algorithms. 2. ** Situation Creation and Question Guidance ** - Creating a suitable situation was very helpful to teaching. For example, the introduction of addition teaching from the pictures of the World Exposition could arouse the enthusiasm of students to learn. At the same time, it allowed students to find mathematical information in the situation and experience the connection between addition and life. - In the process of teaching, the social practice situations such as the different ticket prices of different means of transportation were used to let students experience the significance of deduction in comparison and feel the connection between deduction and life. Moreover, it allowed students to discover, raise, and solve problems independently in specific situations, experience independent thinking, take the initiative to explore, report and communicate, and so on. Finally, the teacher would focus on introducing a main method that would help students form a representation and experience mathematical ideas. - However, there might be problems in the creation of situations, such as the data processing in some situations that might make students confused. For example, in a teaching situation where 500 bottles were given once, 520 bottles were given in the first two weeks, and the remaining 20 bottles were ignored in the teaching. This may cause students to have doubts and need to better deal with the data logic in this situation. 3. ** Estimated Teaching ** - The cultivation of estimation ability was part of the teaching. However, there were some puzzles in the teaching. For example, the format of the estimation formula was not clear. It was not known whether the students should directly write the approximate calculation result (such as 190 + 220 = 410) or use the half-text and half-algorithm format (such as 192+219 is approximately equal to 190+220 = 410). - Students had a biased understanding of estimation, and there was a situation where they estimated for the sake of estimation. Some students would first calculate the accurate answer and then find an approximate number as an estimate, and most students would not use the estimation method to test the rationality of the calculation results. ** 2. Student learning ** 1. ** Cultivation of computing ability ** - In the cultivation of computing ability, one must pay attention to correct, flexible, reasonable, and concise operations. For example, in the process of solving problems, students should be allowed to choose the calculation method flexibly according to the actual situation. For example, in the situation where estimation and precise calculation were needed, students should improve their computing ability. - In teaching, open questions were designed to allow students to solve the problem in different ways (multiple solutions for one question). In the observation and comparison of different methods, they chose a reasonable and concise calculation path. - However, there might be insufficient practice in actual teaching, resulting in students not being able to consolidate their knowledge well and affecting the improvement of their computing ability. 2. ** Attention to Individual Students ** - In the teaching process, the individual differences of the students should be fully taken into account, including their acceptance ability and psychological characteristics. For example, in the teaching of multiplication (such as 300 - 116) where there are zeros in the middle of the minuend, it may be because the students do not have a good grasp of the learning situation, and the situation of individual students listening to the class and mastering the knowledge is not ideal. When students explore the calculation process (such as demonstration 300 - 116), the teacher should give enough time for the students to think. They should not be in a hurry to explain. They should face all the students and let the students inspire each other to find a solution to the problem. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The teaching plan and reflection of addition and substitution of rational numbers
The following is a teaching plan for the addition and substitution of rational numbers: ** 1. Teaching objectives ** 1. ** Knowledge and Skill Target ** - Students can understand the concept of algebra and algebra. - He understood that addition and deduction of rational numbers could be transformed into each other, and he was familiar with the mixed operation of addition and deduction. 2. ** Course, Method, and Target ** - Through the learning of rational number addition and deduction, the students 'calculation accuracy and verbal expression ability were cultivated. - Let the students experience the transformation of mathematics in the process of calculation. 3. ** Emotions, attitudes, and values ** - It allowed the students to experience the beauty of the mathematical unification of all addition and substitution operations. - By solving related computational problems, students would be interested in mathematics and feel the value of mathematics in their lives. ** 2. Important and Difficult Points in Teaching ** 1. ** Main point ** - He understood the addition and subtract hybrid algorithm as an addition algorithm. 2. ** Difficulty ** - The form of omitting the bracketed sum was directly calculated by rational addition. ** 3. Teaching Method ** Using the trial and error method, the corresponding practice questions were set up in each teaching link to consolidate and disperse the difficult points, so that the students could gradually grasp the key points of knowledge. ** 4. Teaching process ** 1. ** Review and import ** - Give the formulas for addition and substitution of rational numbers, such as-9 +(+6),(-11)-7. - Ask the students to read out the formula, identify the two meanings of "+" and "-" in the formula (property symbol and operation symbol), and calculate the result. In this process, he reviewed the operation rules of addition and substitution of rational numbers, emphasizing that the substitution could be converted into addition to prepare for the subsequent mixed operation. 2. ** Teaching of new knowledge ** - This is to introduce the concept of algebra and let the students understand the relationship between addition and deduction of rational numbers. For example, for an addition and subtract hybrid algorithm, deducting a number was equivalent to adding the opposite of the number, thus converting the algorithm into an addition algorithm. - He explained the steps of the addition and reduction hybrid operation. First, he observed the numbers in the formula. If there were decimals, they could be converted into scores (when there were both scores and decimals in the formula). Then, he converted the deduction into addition, and then used the operation law of addition (such as the commutative law and the association law) to perform simple calculations. For example, for the formula-2.5 +3 - 1.5, you can first combine-2.5 and-1.5, because they add up to-4, and then add 3 to get-1. - Through specific examples, such as mixed calculations that include fraction and decimals, the calculation process will be shown in detail, allowing students to master the calculation skills. 3. ** Class practice ** - Arrange an appropriate amount of rational number addition and reduction mixed operation exercises for students to practice in class. The types of practice questions could include simple integral mixed operations, mixed operations that included scores or decimals, mixed operations that required simple calculations using operational laws, and so on. - During the students 'practice, they would patrol and guide them, discover the students' problems in time, and correct them. 4. ** Class summary ** - Review the key content of this lesson with the students, including the concept of algebra and, the conversion of rational addition and substitution, the steps and techniques of addition and substitution, etc. - It emphasized the problems that needed to be paid attention to in the process of calculation, such as the processing of symbols and the correct use of operational laws. ** 5. Reflection on Teaching ** 1. ** Success ** - Through the review and introduction, it could better arouse the students 'memory of addition and substitution of rational numbers, which laid the foundation for the learning of mixed operations. - In the process of teaching new knowledge, he would explain it with specific examples to make abstract concepts and calculation rules more intuitive, which would help students understand and master them. - The classroom practice session could provide feedback on the students 'learning situation in time, so that teachers could adjust their teaching strategies. 2. ** Inadequacies ** - In the teaching process, it was possible that some students with learning difficulties were not paid enough attention, resulting in them having difficulty understanding and mastering computational skills. - The difficulty level of the practice questions might not be reasonable enough. For some students with better foundations, it was not challenging enough. 3. ** Modification measures ** - In the future, more attention should be paid to students with learning difficulties. Individual tutoring or group help should be used to help them keep up with the teaching progress. - The design of the practice questions was optimized and more challenging questions were set to meet the needs of students at different levels. At the same time, it could add some practical application questions to allow students to better understand the practical significance of rational addition and deduction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reflection on the addition of numbers within 5
The following are some reflections on the teaching of addition within 5: ** I. Teaching content and methods ** 1. ** Teaching based on student foundation ** - The addition of numbers within 5 was taught on the basis of the students 'understanding of numbers within 5 and their preliminary understanding of the meaning of addition. Students might have a certain foundation in kindergarten, and teaching should further deepen their understanding on this basis. - For example, in the teaching process, one could pave the way for the addition teaching by reviewing the division and combination of numbers, such as letting the students set up the learning tools, stacking three or five learning tools, etc., to arouse the students 'memory of the knowledge they had learned. 2. ** Creating a situation and understanding the meaning of addition ** - Creating a lively and interesting situation is very important for the junior students to understand the meaning of addition. He could use the scenes of daily life, such as children watering flowers, to guide the students to describe the meaning of the picture. From how many children there were in the beginning to how many children there were now, he could use this process to let the students experience the calculation of adding two parts together to find the total number. - In this process, the teacher had to guide the students to gradually abstract the concept of addition from the specific situation description. For example, from "3 children and 2 children add up to 5 children", abstract "3 + 2=5", let the students have a deep understanding of "add up", and combine the image "together" with the meaning "together". 3. ** Diverse calculation methods ** - Students are encouraged to use a variety of methods to calculate addition within 5. For example, when calculating 3+2, students could count the total number on the map, or they could use the knowledge of the division and combination of numbers to think of 3 and 2 combining into 5 to get the result. Teachers were not in a hurry to introduce the most optimal method to the students. Instead, they allowed the students to think independently and express their own opinions. This not only protected the students 'enthusiasm for learning, but also broadened their thinking and promoted the development of their personalities. ** 2. Students 'Experience and Habit Cultivation in the Teaching Course ** 1. ** Student's emotional experience ** - In teaching, one should pay attention to whether the students 'learning was meaningful. In addition to letting the students learn new knowledge, they also had to let the students have a good and positive emotional experience in the learning process and have a strong desire to learn further. For example, when a student can understand the meaning of addition in a vivid situation and can use addition to calculate, there will be such a positive emotional experience. 2. ** Cultivating study habits ** - They should strive to cultivate good mathematics learning habits, such as observation habits, thinking habits, mental arithmetic habits, draft habits, and so on. These habits couldn't be formed in a short period of time. They needed to be guided by teachers in the teaching process for a long time. For example, when teaching addition within 5, whether it was to let the students observe the situation map, think about the calculation method, or do simple mental arithmetic, they had to permeate the awareness of habit cultivation. ** 3. Design of the practice session ** 1. ** Practice Level and Target ** - The practice design had to be layered, from the intuitive image to the abstract summary. For example, in the exercises in " Think and Do ", the first question asked the students to explain the meaning of the picture clearly to highlight the meaning of addition; the second question further understood the meaning and calculation method of addition through drawing operations; the third question focused on instructing the students to use the method of " combining a few and a few " to calculate verbally. This kind of practice was in line with the student's cognitive development law and gradually improved the student's ability. - Different forms of practice could meet the needs of students with different abilities, such as swinging and speaking, connecting actions and language; looking at the calculation and swinging to show the combination of numbers and shapes; speaking and filling in to let the students observe the situation map to explain their own meaning, ask questions, list calculations, and discover the rules of calculations; calculating and filling in directly tested the students 'calculation ability. 2. ** Regrets and improvements in practice ** - After completing the basic requirements, they could add an expansion segment, such as asking students to think about which events in their lives could be expressed by addition formulas. This way, students could understand the connection between mathematics and life, and improve their verbal skills and love for mathematics. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Self-made teaching plan and reflection on the application of addition and substitution
#<Self-made teaching plan for big class of addition and substitution application questions> ##1. Teaching objectives 1. Let the children learn how to write their own addition and substitution problems. 2. Cultivate children's thinking flexibility, agility, logic and oral expression. 3. To develop the child's visual ability and judgment. ##2. Teaching preparation 1. Arithmetic cards, a slide, a number of flowers (or other small items), a drum, a picture (containing a different number of animals or objects), and a set of numbered cards for each person. 2. Ask the parents to take the children to buy things in advance so that the children understand the process of buying and selling. Prepare 10 Math Books for Children, 10 calculation cards, and 10 fruit cards. ##3. Teaching process ###(1) Introduction of revision 1. Through games (such as Sunshine Express), review addition and multiplication within 10. For example, if the teacher said that the calculation was "2 + 3 =", the child would answer "5". 2. Show a slide, the content is some addition scenes, such as children playing on the playground, monkey activities on the grass, the number of trucks in the parking lot, etc., let the children answer the calculation and the number according to the picture. You can use the method of answering first, group competition, or collective answer. ###(2) Adding applied problems 1. ** Create a scenario and write a question ** - Ask the two children to come to the front. The teacher will give two flowers to one child and three flowers to the other child. Then ask,"What is the teacher doing?" Following that, he used the two numbers "2" and "3" to demonstrate an addition problem."The teacher gave the children red flowers. First, he gave the children two red flowers. Then, he gave the children three red flowers. How many red flowers did the teacher give in total?" Guide the child to list the calculations. 2. ** Explain how to write questions ** - By repeatedly asking,"What's the thing in this question? What were the two known numbers? What was the last question?" Explain to the children the basic methods and steps of making addition application problems. ###(3) Subtraction word problems teaching (can be compared to addition word problems teaching steps) 1. ** Create a scenario and write a question ** - For example, if the teacher showed five apples and took away two, he would ask the child,"There were originally five apples. Now that two are taken away, how many apples are left?" Guide the child to write the formula "5 - 2 = 3". 2. ** Explain how to write questions ** - Similarly, by asking,"What does this question talk about? Which two numbers do you know? What's the problem?" To let the children understand the composition of the multiplication word problem. ###(4) Consolidating Practice 1. ** Training with supplementary questions ** - For example, if there were originally three planes in the sky and four more planes flew over, the teacher would first make up the questions, then inspire the children to think whether it was complete, and guide the children to ask the question,"How many planes are there in the sky?" He also asked the child to explain the problem completely and write down the formula. 2. ** Practice of drawing pictures and writing questions ** - Show the picture (if there are ducks in the picture, the size, color and position are different). Ask the child to write an addition or deduction problem according to the picture, and use the card to arrange the calculation. 3. ** You make it up, I make it up ** - Two people in a group, one person wrote the questions, and the other set the calculations. ###(5) Organizing the game-pass the ball and make up application questions The child listened to the drumbeat and passed the ball. When the drumbeat stopped, the child who got the ball ran to the front and used what he usually saw, heard, or did to make up an addition or deduction application question for everyone to listen to. If he made it right, the teacher would reward him with a small red flower. The game was repeated. ###(6) Evaluation Teacher: Today, we learned how to write addition and substitution problems. There are three conditions for writing a problem. First, you have to say one thing. Second, you have to have two numbers. Third, you have to have a problem. Please use your brains to come up with more and better problems when you go back. ##IV. Reflection on Teaching 1. ** Children's learning situation ** - In the whole teaching activity,"application questions" were difficult for the children to understand and master. Some of the children performed well in the creation and solution of the addition problem, and they could understand the concept of adding two parts to get a total number. However, in the deduction problem, some children had difficulty understanding the known total number and one part to find the other part. For example, in a deduction problem involving a specific scene, such as taking a part of a group of items to find the remaining part, the child may confuse the relationship between quantity and quantity. 2. ** The effectiveness of teaching methods ** - Scenarios and games could better attract children's attention and increase their participation. For example, by giving flowers to children and showing the change in the number of apples, children could intuitively feel the relationship between numbers, which would help them understand the structure of the application questions. In the game segment, the method of passing the ball to make up the application questions stimulated the children's sense of competition and prompted them to think and create actively. However, children with weaker comprehension abilities may need more one-on-one guidance. 3. ** Combination of life experience and teaching ** - It was helpful for children to experience the process of buying things in advance. Many children could apply the buying and selling relationship in shopping to the creation of application questions, such as "I have 5 yuan, but I bought a 3 yuan toy. How much money do I have left?" This shows that connecting mathematics education with real life can enhance children's understanding and application of mathematical concepts. However, he could still further explore other scenes in life, so that children could have more material to create. 4. ** Modification measures ** - In future teaching, more different types of practice methods could be added, such as group competition, mutual error correction, etc., to strengthen children's understanding of applied problems. For children who had difficulty understanding, they could design some simple exercises and guide them step by step from the most basic number relationship. At the same time, continue to strengthen the connection between mathematics education and life, encourage children to observe mathematical phenomena in life, and improve their ability to use mathematical knowledge to solve practical problems. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
My hometown teaching plan, big class teaching plan reflection
The following is an example of reflection on the teaching plan of a large class in his hometown: * * 1. Achievement of teaching objectives ** 1. * * Knowledge and Skills ** - In many hometown-themed class plans, the goal usually included letting the child understand the geographical location, specialties, scenic spots, and so on. If the child could accurately describe some of the characteristics of his hometown, such as knowing some famous specialties or scenic spots in his hometown, it meant that this part of the goal was achieved. However, if a child had difficulty describing a geographical location, such as simply pointing out the approximate location of his hometown on a map, it might indicate that the use of map tools for teaching was not deep enough or the teaching method was not intuitive enough. 2. * * Emotions, attitudes, values ** - When children showed their love for their hometown during the activities, such as actively sharing their feelings about the things in their hometown and being proud of the specialties of their hometown, it indicated that they had achieved success in stimulating the emotional goal of children's love for their hometown. However, if the children's participation was not high and they lacked interest in topics related to their hometown, it might be that they did not fully capture the curiosity of the children during the introduction process or activities, and did not let them truly feel the unique charm of their hometown. * * II. Usage of teaching methods ** 1. * * Multimedia-assisted teaching method ** - If the teaching plan used the multi-media to show the scenery of his hometown and the production process of specialties, the effectiveness could be judged from the children's reactions. If the child was focused when watching the multi-media materials and could actively discuss the content, it meant that this method could stimulate the child's curiosity and desire to explore. On the other hand, if the child's response to the content of the multi-media display is cold, it may be that the content is not vivid enough, interesting enough, or not closely related to the child's actual life. 2. * * role-playing method ** - For the lesson plan that used role-playing to experience the culture of their hometown, when the child could immerse himself in the role, such as enthusiastically introducing the characteristics of his hometown when he played the role of a small tour guide, it showed that the role-playing method effectively strengthened the child's emotional identity with his hometown. However, if the child did not understand the role or was unable to interact effectively during role-playing, it might be a problem with the role setting or guidance, such as not giving the child enough background knowledge or demonstration. 3. * * Organization interview method ** - If the child learned about his hometown by interviewing parents or community residents, and was able to organize and share the information obtained from the interview, it meant that the organizational interview method had cultivated the child's ability to collect and organize information. However, if the child did not know how to ask questions during the interview or the interview results were not satisfactory, it might be that the teacher did not give enough guidance before the interview, such as how to design the interview questions and how to conduct the interview politely. * * 3. Teaching content ** 1. * * Complete content ** - Some teaching plans in their hometowns might focus on the natural landscape and specialties of their hometowns, ignoring the cultural traditions, customs, and other aspects of their hometowns. This might cause the child to have a less comprehensive understanding of his hometown. For example, if only the delicacies of their hometown were introduced without mentioning the traditional festivals and celebrations of their hometown, the children's understanding of their hometown culture would be more one-sided. 2. * * Difficulty Level of the content ** - If the teaching content was too complicated, such as using too esoteric language or concepts when introducing the historical changes of their hometown, it might be difficult for young children to understand. On the contrary, if the content was too simple, such as simply listing a few scenic spots in his hometown, it might not be able to satisfy the child's thirst for knowledge, nor could it deeply stimulate the child's love for his hometown. * * 4. Homeland Cooperation ** 1. * * Cooperation Effect ** - In many successful teaching plans in his hometown, the homeland cooperation played an important role. For example, parents could take their children to visit the scenic spots in their hometown and collect information about their hometown's specialties. If the children could actively share the content about their hometown that they had prepared with their parents at home, it meant that the cooperation between the home and the parents had achieved good results. However, if the parents 'participation was low, the children did not have enough extra-cursory resources to support classroom learning. This required teachers to further strengthen communication with parents to increase the importance and enthusiasm of parents to participate in teaching activities. 2. * * Resource utilization ** - Homeland cooperation could bring rich educational resources. If teachers could make full use of the resources provided by parents, such as making teaching materials from photos of their hometown taken by parents, or inviting parents to share stories about their hometown in class, it would enrich the teaching content and improve the teaching effect. If these resources were not fully utilized, precious educational resources would be wasted and the quality of teaching would be affected. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
