Parity problem, second grade
The odd-even problem in the second grade of primary school was mainly about the understanding and simple application of the basic properties of odd and even numbers. Odd numbers referred to numbers like 1, 3, 5, 7, etc., and even numbers referred to numbers like 2, 4, 6, 8, etc. Its basic properties were as follows: 1. Odd + odd = even, for example, 3 + 7 = 10. 2. Even + even = even, for example, 2 + 4 = 6. 3. Odd + even = odd, for example, 3 + 4 = 7. 4. Even numbers-even numbers = even numbers, for example, 8 - 2 = 6. 5. Odd-odd = even, for example, 7 - 1 = 6. 6. Even-odd = odd, for example, 10 - 1 = 9. 7. Odd-even = odd, for example, 9 - 2 = 7. 8. Odd x odd = odd, for example, 3 x 3 = 9. 9. Even number × even number = even number, for example, 2×2 = 4. 10. Odd x even = even, for example, 3 x 2 = 6. For example, there might be such a question: determine whether the result of adding or deducting two numbers is odd or even; or in some distribution problems, determine whether it is feasible according to the oddness, such as distributing a number of items evenly on several plates, each plate requires an odd number of items, and determine whether it can be done.

Fourth grade math dice problem
Dice was a cube. The common six-sided dice had one to six numbers on it, and the number on the opposite side must be seven. China dice were used to paint one and four red. In the fourth grade mathematics questions about dice, there were questions such as calculating the size of the sum of the numbers of two dice facing up to determine whether the game was fair. For example, if the sum of the numbers on the two dice was greater than or equal to 7, Xiaoxiao would win, and if the sum was less than 7, Naughty would win. It might also involve the calculation of the sum of the numbers on the hidden side of the die, which needed to be calculated according to the numerical characteristics of the die. At the same time, the number of points rolled by the die was a random number from 1 to 6. The results of each roll were independent of each other. This also provided the foundation for some preliminary ideas about probability and statistics. In the teaching, the students would be able to master the basic shape, number, and throwing calculation of the dice through the model of the dice. They would also be able to cultivate hand-eye coordination and spatial sense. There would also be dice calculation games to deepen the students 'understanding of the dice points and calculation.

Biology Grade One Second Semester Problem
The biology problems in the second semester of the first year of high school were mainly focused on genetics. This part was recognized as a difficult part of high school biology. The difficulty was mainly reflected in the following aspects: - Genetics involved a lot of calculations, but there was little content about calculations in textbooks. Many children could not find the direction of learning and could not understand it by reading textbooks. - Genetics accounted for a large portion of the score in the exam. Whether it was to achieve a score of 60 or 90, genetics played a key role. - From the difficult training materials, things like the experimental exploration of the molecular basis of inheritance, the application of the basic laws of inheritance, the understanding of the graph curve of the cell basis of inheritance, etc. were all difficult contents based on genetics. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Second Grade, Second Volume, Reflection on Problem-solving
The following are some aspects of the second volume of the second year's reflection on teaching problem solving: * * I. Reflection on the teaching of solving problems in hybrid operations ** 1. * * Teaching preparation and goals ** - It was necessary to exchange teaching methods with colleagues and learn from their experiences before teaching the problem solving in hybrid operations. This would help to have a clearer goal and train of thought in class, thus improving the teaching effect. 2. * * Student performance and problems ** - * * Confidence and expression ** - There was a lack of confidence among the students in the classroom. Many students did not like to raise their hands to answer questions even if they knew how to. Moreover, they lacked the ability to express themselves. Some students understood the meaning but could not express it clearly. Most of the students did not dare and were unwilling to express themselves. They were willing to be listeners. - This could be caused by many reasons, such as the student's personality, their own ability, or the class atmosphere, but the teacher's responsibility was also greater. Even though he knew the importance of praising and encouraging the students, the classroom atmosphere was not lively due to his lack of skills and his inability to fully motivate the students to speak. - * * Interdisciplinary Connection ** - In mathematics class, they paid too much attention to the mastery of basic knowledge and neglected the training and cultivation of students 'language ability, making students unable to express their thoughts well. 3. * * Modification measures ** - Teachers should make appropriate and positive evaluations of students 'performance in a timely manner, encourage students more, stimulate students' motivation to learn, enhance self-confidence, stimulate students 'thinking, let students experience success and happiness in their studies, and make the classroom more attractive. - The importance of the relationship between the various disciplines, in mathematics class, can not ignore the cultivation of students 'language expression ability, because language and thinking are closely related, language expression ability will help to think more flexible. * * II. Reflection on the Development of Problem-solving Teaching from Grade 1 to Grade 2 ** 1. * * Question types and student myths ** - From the first to the second grade, the problem solving process progressed from the initial picture to the word question, and the students 'understanding and reading ability were required to increase. The first volume of the first year involved many types of problem solving, such as drawing a picture. - Students 'misconceptions were mainly manifested in: not understanding the meaning of the question and not answering the question; not being able to distinguish between information and questions and calculating the question as information; adding and deducting errors. 2. * * Cause Analysis ** - * * In terms of objective aspects ** - It could be due to insufficient practice, delayed feedback, and weak abstract thinking. - * * Subjectively ** - Students 'poor computational ability, incomplete language comprehension, and imperfect visual and auditory development were the reasons for the myths. 3. * * Coping Strategy ** - Pay attention to the cultivation of students 'ability to read the questions, and use a variety of methods to read the questions and read them many times. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Elementary school fourth grade figure problem explanation
There were many types of fourth-grade graphic questions. The following are some common types and explanations: * * 1. Combination of a rectangular and a square. ** 1. * * Cut out the rectangular problem of the square ** - For example, there was a question like this: Cut off a square from a rectangular shape. The remaining lengths of the two sides were 6 cm and 3 cm respectively, and the total area of the remaining figure was 54 square centimeters. - If you use an equation solution (suitable for those who have learned the one-dimensional equation): Let the side length of the cut square be x, you can get the equation (6x +3·(6 + x)= 54). First, expand the equation to get x (6x +18 + 3x = 54), and then combine the similar terms to get x (9x = 54 - 18). - For fourth-year students who hadn't learned equations, they could use auxiliary lines to divide the graph to solve it. First, he made an auxiliary line to divide the remaining figure into three parts. The length and width of the rectangular shape in the lower right corner were 6 cm and 3 cm respectively, and its area was [6 × 3 = 18] square centimeters. In the other two figures, the cut squares share the same side as them, so their areas are the side length of the square (× 3) and the side length of the square (× 6). Therefore, the side length of the square is [=(54 - 3 × 6) × (3 + 6)= 36 × 9 = 4] cm. * * Two, two square combination related graphic questions ** 1. * * The application of the sum and difference problem in the combination of two squares ** - For example, if the sum of the sides of two squares is 20 and the difference in area is 40, find the area of the small square on the left. - Solution: When two squares are placed side by side, you can first draw a similar small square inside the big square, divide the area difference into two pieces, and fill one of them in the appropriate position, so that the area of the new figure is the value of the area difference (for example, 40 here). He could use the sum and difference relationship to solve for the length of the side, and then find the area of the small square. If the area difference was divided into two equal pieces (using the symmetries), these two pieces were both pyramids, and the top and bottom were the sum of the two sides (20 here). Then, the sum and difference relationship was used to find the relevant side length and other data, and finally the small square area was found. Generally speaking, the fourth grade's graphics questions focused on the understanding of the properties of basic graphics (such as the length of the side, the area, etc.), as well as the use of clever division, combination, and difference relations to solve complex combination graphics problems. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Multiplication, problem solving, reflection on teaching, third grade
The following are some possible aspects of reflection on third-year multiplication problem solving: ** 1. Knowledge and Skills ** 1. ** Understanding and application of algorithms ** - When teaching multiplication to solve problems, one had to pay attention to the depth of the student's understanding of the meaning of multiplication. For example, in a two-step multiplication application question, could the student accurately determine the steps of the multiplication operation based on the numerical relationship in the question? For example, each ping pong ball is 2 yuan, and there are 5 ping pong balls in a bag. Please ask for the total price of 6 bags of ping pong balls. Students need to understand that the price of a bag is calculated by "the number of bags x the price of each bag", and then multiplied by the number of bags to get the total price, or the total number of table tennis balls is first calculated and then multiplied by the unit price to get the total price. If students had problems with this, it might reflect a lack of familiarity with the concept of multiplication in practical situations. - For the calculation of three-digit multiplication by two-digit multiplication, he had to consider whether the students could successfully transfer the calculation theory and algorithm of two-digit multiplication by two-digit. During the teaching process, some students might find that although they could calculate the results mechanically according to the calculation steps, they were not clear about what each result represented and why they were calculated. This would require a stronger explanation of mathematics in the teaching. For example, by letting the students understand it in light of specific situations, such as calculating Uncle Li's train journey (speed x time), so that the students could understand the meaning of each digit multiplication and the principle of carry. 2. ** Calculation accuracy ** - A third year student might make mistakes in multiplication because they were not familiar with the multiplication formula. For example, in some simple multiplication calculations, such as 43×30, if the student memorized the chant wrongly or made a mistake in addition, the result would be wrong. In the reflection of teaching, he had to consider whether he had strengthened the memory of the multiplication formula and the practice of simple mental arithmetic in his daily teaching. At the same time, he had to think about how to better let the students master the error-prone areas in the calculation of multiplication, such as digital alignment, carry, etc. 3. ** Problem solving strategies are diverse ** - Students should be encouraged to use different strategies in solving multiplication problems. For example, in the two-step multiplication problem, some students might start from the relationship between unit price and quantity, while some students might start from the relationship between total quantity and partial quantity. Teachers should reflect on whether they gave students enough space to explore different solution methods in the classroom, and whether they should guide students to compare and analyze different solution strategies so that students could better understand the application of multiplication in different situations. ** 2. Teaching methods and processes ** 1. ** The effectiveness of situation creation ** - If you create a situation related to multiplication in the teaching, such as shopping, travel, etc., to lead to multiplication to solve the problem, you have to reflect on whether these situations really help students understand the meaning and application of multiplication. For example, whether the situation was too complicated to distract the student from the multiplication relationship, or whether the situation was out of touch with the student's life, making it difficult for the student to connect what he had learned with the situation. 2. ** Students 'independent learning and cooperative exchange ** - They had to consider whether they should give students enough time to study independently during the teaching process. For example, when exploring the method of solving multiplication problems, did the students have enough time to think about the problem independently and try different ways of solving the problem? At the same time, for the group cooperation and exchange session, they had to reflect on whether the group division was reasonable and whether every student could participate in the discussion. After the group exchange, the whole class exchange session could fully display the results of the students 'thinking, so that different solution methods could be shared and discussed. 3. ** Practice and feedback ** - Whether the practice design in the teaching was reasonable and whether it covered different types of multiplication problems. For example, whether there were enough basic exercises to consolidate the multiplication calculation skills, whether there were extended exercises to develop the students 'ability to solve complex multiplication problems. During the post-practice feedback session, whether or not they could discover the students 'mistakes in time and provide targeted explanations. For example, when displaying students 'wrong homework, could they guide the students to accurately find the cause of the error and correct it, while letting other students learn from it. ** 3. Students 'learning attitudes and habits ** 1. ** Learning enthusiasm ** - He had to reflect on the enthusiasm of the students in the process of solving problems by multiplication. If the student participation was not high, it might be because the teaching method was not attractive enough, or the difficulty of the questions was too high or too low. For example, if the questions were too simple, the students would not find them challenging. If the questions were too difficult, the students would feel afraid of the difficulties, which would affect their enthusiasm for learning. 2. ** Cultivating study habits ** - Whether or not they pay attention to cultivating students 'good study habits in teaching, such as the habit of carefully examining questions. In the multiplication problem solving, whether the student could accurately extract the key information from the question and determine whether it was a one-step multiplication or a two-step multiplication. At the same time, when students shared their ideas and methods in class, they were encouraged to express them in a complete mathematical language to cultivate students 'rigorous thinking habits. If the students did not perform well in these areas, they had to think about how to improve them in subsequent teaching. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
