Illustration of the Primary Mathematics Teaching Materials of the People's Education Press
There were three main problems in the illustrations of the primary school mathematics textbook published by the People's Education Press: Firstly, it was not beautiful and was not up to the standard of cultivating people. The overall painting style did not conform to the public's aesthetic habits. Some of the illustrations were ugly and did not have a good mental outlook, which did not properly reflect the sunny image of our country's children. Second, it was not strictly regulated, and some illustrations even had mistakes. There were too many illustrations, and some of the illustrations were not of high professional standards. There were scientific and standardized problems. Third, it was not detailed and accurate, and some of the illustrations were easy to misread. Some of the illustrations were rough, some of the lines and elements were not properly drawn, and the proportions of the pictures were not coordinated. In addition, as a teaching material compilation unit, the People's Education Society did not fully and thoroughly implement the relevant decisions and arrangements of the central government, did not fully understand the educational function of teaching material illustrations, the selection system of illustration authors was not perfect and standardized, the implementation of the teaching material three-review and three-school system was not strict, the internal error correction system was not perfect, the opinions of readers were not valued, and the problems existing in the illustrations were not seriously investigated and rectified in time. When the Teaching Materials Bureau of the Ministry of Education organized experts to carry out the review of teaching materials, there were also situations such as insufficient guidance, insufficient supervision, and inadequate supervision of the investigation and correction of teaching materials. However, after investigation, it was found that there was no economic benefit transfer between the relevant personnel of the People's Education Society, the illustrator Wu Yong, and the general consultant of the overall design art of the teaching materials, Lu Jingren. In the end, according to the relevant regulations, the relevant units and 27 dereliction of duty personnel were severely held accountable. Read more exciting novels for free
A Case Study of Primary School Mathematics Teaching published by the People's Education Press
The following is an analysis of the case study of primary school mathematics teaching published by the People's Education Press: ** 1. Teaching objectives ** 1. ** Knowledge target ** - In many teaching cases, it was clearly stated that students should master specific mathematical knowledge calculation methods, such as the calculation method of multiplying two or three digits by one digit (carry). This would help students build a mathematical knowledge system and lay the foundation for subsequent studies. For example, through specific multiplication calculations, students could gradually master the rules of multiplication. 2. ** Ability Target ** - Focus on cultivating students 'ability to raise and solve problems. For example, in the teaching process, students would be guided to observe the situation map and ask mathematical problems, and then try to solve them. The cultivation of this ability would help improve the students 'mathematical thinking ability and application ability, allowing them to learn to look at things around them with a mathematical perspective. 3. ** Emotional goal ** - It emphasized the connection between mathematics and life and increased students 'interest in learning mathematics. When mathematics knowledge was combined with reality, students could feel the practicality of mathematics and thus increase their enthusiasm for learning. For example, when explaining the concept of "possibility," he could relate it to the scene of dice rolling in real life to let the students better understand the concept. ** 2. Teaching Points and Difficulties ** 1. ** Teaching Focus ** - It usually focused on the mastery of specific mathematical knowledge, such as the correct application of a certain calculation method. For example, in the teaching of two-digit and three-digit numbers multiplied by one-digit numbers (carry), the focus was to let the students explore and master the correct calculation method. This was the core content of classroom teaching, and teachers needed to let students understand and master it in many ways. 2. ** Teaching Difficulties ** - It was more reflected in using knowledge to solve simple problems in life. Due to the complexity and variety of real-life problems, students needed to flexibly apply what they had learned, which was a challenge to their thinking ability and comprehensive application ability. For example, when encountering application questions involving multiple conditions, students needed to accurately analyze the problem and choose the appropriate method to solve it. ** 3. Analysis of the teaching process ** 1. ** Review session ** - The review session helped to consolidate the knowledge that the students had learned before and lay the foundation for the learning of new knowledge. For example, when teaching two-digit multiplication, let the students look at the picture independently, describe the meaning of the picture, and ask questions and answers to each other. This could activate the students 'existing knowledge reserves and increase their participation in subsequent learning. 2. ** Extending the application segment ** - This segment was designed to allow students to apply what they had learned to practical problems and deepen their understanding of the knowledge. For example, through various forms of practice questions, such as connecting, solving real-life problems such as shopping, visiting, etc., students could use multiplication knowledge in different situations to improve their ability to solve problems and transfer knowledge. 3. ** Wrap-up segment ** - The summary could help the students sort out the knowledge they had learned and clarify the things to pay attention to in the learning process. For example, after learning two-digit multiplication, the teacher would guide the students to summarize the main points of the calculation, which would help the students strengthen their memory and improve the accuracy of the calculation. ** 4. Teaching Methods ** 1. ** Group learning ** - Some teaching cases involved group cooperative learning, but there were also some problems. For example, in the teaching clip of Multiplication with Fraction, if the relationship between group cooperation and independent thinking was not handled well, it might lead to poor cooperation. Teachers needed to ensure that students had time to think independently before working in groups, that there was sufficient time and space for cooperation, and that there was a clear division of roles. Only then could group cooperation play its due role. 2. ** Setting up a scenario ** - It was an effective teaching method to create a teaching situation based on the reality of life. For example, when explaining "possibility," he would use the example of dice rolling in real life, or when explaining the concept of area, he would create a situation by comparing the area of a square and a rectangular. This would allow students to better understand abstract mathematical concepts, increase their personal experience, and improve the quality of teaching. 3. ** Case Study Guidance Learning ** - Choosing suitable teaching cases could improve students 'comprehension. For example, when discussing the concept of area, students were encouraged to explore their own methods by comparing the size of a square and a rectangular. In this process, students could understand the concept of area in depth, rather than simply accepting the teacher's direct explanation. 4. ** Extra-cursory Practice ** - Carrying out extra-cursory practice can enhance students 'ability to use mathematics. Because mathematics was more abstract, primary school students had limited thinking ability. Extra-cursory practice could enrich students 'imagination and allow them to better learn and apply mathematical knowledge in practice. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reflection on the Mathematics Teaching of Grade One of the People's Education Press
The following is an example of a post-teaching reflection on the PEP's Grade One Mathematics: There were many aspects worth reflecting on in the mathematics teaching process of Grade One. In terms of teaching content, there were many basic knowledge points in Grade One Mathematics. For example, the rational numbers section included the classification of rational numbers, number axes, opposite numbers, absolute values, and other concepts. These concepts were new and abstract to students. In the process of teaching, if there were not enough examples and intuitive graphics, some students might not be able to understand it thoroughly. For example, the concept of absolute value required students to be familiar with its algebra and geometry meaning. In actual teaching, students should be guided to understand the geometric meaning of the absolute value representing the distance of a number to the origin from the number axis, and then extend it to the non-negativity in the algebra sense. This would help to deepen their understanding. In terms of teaching methods, group cooperative learning was a more effective way. For example, in the exploration of practical problems and the teaching of linear equations, group cooperation could give full play to the students 'subjective initiative. However, the students 'learning ability, personality, and other factors needed to be considered when dividing the groups to ensure that the members of the group could communicate and cooperate effectively. Moreover, in the process of group cooperation, the teacher's guiding role was crucial. They had to find the problems of the students in time and give appropriate guidance to avoid the group discussion from straying from the topic or the lack of participation of some students. The design of the teaching process also needed to be carefully planned. For example, when introducing new topics, using real-life examples could increase students 'interest in learning. For example, using the sales problem of the computer city to introduce the profit and loss problem in sales, this reflected the concept that mathematics came from life and served life. However, in setting up the questions, one had to pay attention to the difficulty level. If it was too difficult, it might dampen the enthusiasm of the students. If it was too simple, it would not be able to achieve the desired teaching effect. In terms of students 'learning feedback, there was a large individual difference in the mathematics learning of the junior high school students. Some students could quickly grasp new knowledge and apply it flexibly, while some students might have difficulty understanding basic knowledge. This required the teachers to design the homework arrangement and tutoring in different levels, providing homework of different difficulty and targeted tutoring for students of different levels to ensure that every student could improve on their own foundation. In terms of teaching evaluation, motivational language could stimulate students 'motivation to learn, but it could not be limited to this. A comprehensive evaluation system should also be established, including the evaluation of students 'knowledge mastery, performance in the learning process, team cooperation ability, and so on. Only in this way could they have a more comprehensive understanding of students' learning situation and promote their all-round development. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reflection and summary of the teaching plan of the fourth grade of primary school mathematics published by the People's Education Press
The following is a reflection and summary of the teaching plan for the fourth grade of primary school mathematics published by the People's Education Press: ** The first and fourth operation parts ** 1. ** Teaching objectives and actual situation ** - The teaching objectives included allowing students to master the order of operations with two-level operations, correctly calculate three-step problems, feel strategies in solving practical problems, and develop learning habits. However, from the students 'perspective, although they had some preliminary contact with the order of the four operations and the strategy of solving problems, they were not deep enough. For example, although the order of the four operations was encountered in the usual practice, some students relied on their parents 'guidance to familiarize themselves with the order of multiplication and division before addition and addition. Moreover, the students' ability to solve problems was poor. There were problems such as not listing comprehensive formulas, wrong order of operations, weak understanding ability, and simple calculation errors. 2. ** Directions for Teaching and Learning ** - He could visualize the abstract calculation sequence of the comprehensive algorithm. For example, he could use the method of "drawing sequence lines" to enhance the image and make it easier for students to understand. ** 2. Triangular part ** 1. ** The preparation and implementation of inquiry teaching ** - In the teaching of triangle knowledge, knowledge points such as the relationship between the three sides of the triangle, classification, internal angle, and so on could be explored and taught. Teachers should prepare materials before organizing the inquiry, and they should predict and eliminate the improper operation methods that may affect the results of the inquiry. For example, when exploring the relationship between the three sides of a triangle, students prepared their own sticks to explore. Some students came to the wrong conclusion because of improper operation methods (putting the ends of adjacent sticks together instead of overlapping). Therefore, it would be better to unify the understanding of the operation method before the exploration in another class. ** 3. Decimals (Based on the overall situation of the teaching materials, the relevant teaching situation can be inferred)** 1. ** Focus of teaching content ** - The significance and nature of decimals, addition and substitution of decimals, etc. were the key teaching contents. The teaching goal was to let the students understand the meaning and nature of decimals, experience the application, develop their sense of numbers, and master addition and deduction. There might be situations where students 'foundations were overestimated in teaching. In actual teaching, students would also have various problems when learning decimals, such as making more mistakes in homework. ** 4. Overall Teaching ** 1. ** Comprehensive teaching goal achieved ** - In addition to the above key content, there were also teaching objectives such as operational laws and simple calculations, observing objects, graph movement, average and bar graphs, and wide-angle mathematics. The overall teaching should let the students understand the meaning of the four operations, master the relationship between each part, explore the operation law and simple operation; recognize the characteristics, classification, and relationship between the edges and angles of the triangle; be able to identify the shape of objects in different directions and carry out the operation of graphic movement; understand the meaning of the average and carry out simple data analysis; experience the variety of problem solving strategies, etc. Teachers should pay attention to the comprehensive cultivation of students 'abilities in the teaching process, such as the ability to analyze and reason, and the awareness of discovering mathematics in life. At the same time, from the perspective of teaching effectiveness, it may be affected by many factors, such as insufficient attention to the content of the teaching materials. Teachers need to constantly reflect on improving teaching methods to improve the quality of teaching. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reflection on the Primary School Mathematics Teaching Materials
The activity of sorting out primary school mathematics teaching materials had many important meanings and could draw a reflection summary from many aspects. From the perspective of understanding the teaching materials, through the teaching material sorting activity, teachers could form a systematic understanding of the primary school mathematics teaching materials, deeply understand the teaching objectives and difficulties of each volume and each unit, and better grasp the intention of writing the teaching materials, so that they could use the teaching materials more rationally to carry out teaching work. In the improvement of teaching methods, teachers realized that they had to change their traditional ideas and teaching methods. For example, according to the New Course Standard, students should be motivated to learn and provide sufficient opportunities for mathematical activities, so that students can master knowledge and skills, ideas and methods, and obtain activity experience through independent exploration and cooperative communication. At the same time, the classroom questions should be open and targeted, giving affirmation or guidance according to the students 'answers to improve the students' thinking and understanding. Paying attention to the students was also a key point in teaching. For the teaching of the lower grades, attention should be paid to the cultivation of students 'behavior habits, classroom organization ability, learning tool use methods, and the standard cultivation of mathematical language expression ability. Moreover, from the lower grades, quantity relations and mathematical thoughts should be infiltrated. Teaching material sorting activities could also promote communication and cooperation between teachers. For example, in some teaching material training activities, teachers would watch training videos together, and experts would share mistakes and solutions that were easy to make in teaching, which would help improve teachers 'teaching standards. Teachers would also interact with each other, such as passing exams and sharing tips and tricks to further enhance their understanding of the teaching materials. In terms of homework design, organizing teaching materials could make teachers reconsider the value and design principles of homework. For example, the design of summer homework should be based on the students 'interests and feelings, in line with the students' age characteristics, and the teachers should evaluate it. At the same time, it should be implemented, grasp the students 'ideas and make preparations, such as letting the students prepare for the next semester's courses and stick to calculation exercises. In short, the elementary school mathematics textbook sorting activity had positive significance in many aspects of improving teachers 'teaching, and it prompted teachers to constantly reflect and improve their teaching-related work. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The Teaching Design and Reflection of Observing Objects in Fourth-grade Mathematics of People's Education Press
The following is an example of the teaching design and reflection of the fourth grade mathematics "Observing Objects" published by the People's Education Press: ##1. Teaching objectives 1. ** Knowledge and Skill Target ** - Students can accurately identify the shape of a geometric body made of several cubes observed from different positions (front, top, left). - Grasp the correct observation method, such as observing the line of sight to be vertical to the surface being observed. 2. ** Course, Method, and Target ** - Through assembling, observing, imagining, judging, and other activities, the students will experience the process of observing objects. For example, the students could use cubes to piece together a geometric object, and then observe and describe the shape from different directions. - In the group exploration, such as exploring different objects from the same angle, the students 'cooperative communication ability and hands-on operation ability were cultivated. 3. ** Emotions, attitudes, values, goals ** - Cultivate students 'spatial imagination and reasoning ability. - This would allow students to realize that when they observed the same object from different positions, the shapes they saw might be different. When they observed different objects from the same position, the shapes they saw might be the same or different. Thus, they would develop the habit of thinking from multiple angles. ##2. Difficulties in Teaching 1. ** Teaching Focus ** - Able to accurately identify the shape of objects observed from different directions. - In actual observation activities, it is used to abstract a planar figure from the observed object. 2. ** Teaching Difficulties ** - According to the shapes observed from different directions, cubes were used to piece together the corresponding three-dimensional figures. ##3. Teaching Method It adopted the intuitive teaching method, operation exploration method, group cooperation method, etc. Students were allowed to build geometry by themselves, observe objects, and discuss in groups to deepen their understanding of knowledge. ##4. Teaching process 1. ** Introduction of Scenarios ** - Students could use examples from their daily lives, such as showing pictures of cars from different angles. Students could imagine looking at cars from different positions and see if the pictures were the same. Then, students could connect the pictures of cars seen by different people to lead to the topic. This would stimulate the students 'interest in learning, and at the same time, review old knowledge to pave the way for new lessons. 2. ** Exploring new knowledge ** - ** Patchwork Diagram **: Ask the students to work together at the same table and use a certain number of cubes (such as four) to piece together their favorite geometric body. Students were then asked to show and describe the resulting geometry. - ** Observation and comparison **: Students can communicate with each other in the group about what shapes they see from different directions (front, top, left), and they can use small squares to display them. After that, the whole class would communicate, show the observations of different groups, and evaluate them. For example, the teacher could post pictures from the textbook on the blackboard and let the students connect the lines on the stage to strengthen their understanding of the different shapes seen from different positions. 3. ** Consolidating Practice ** - Ask the students to complete the relevant exercises in the textbook, such as the questions in "exercise 4". The students could first observe and identify the lines independently, and then the teacher or the teacher could show the correct answer to check. For some questions that required students to observe the combination of cuboids and cubes, let the students think about the shapes seen from the front, top, and left respectively. 4. ** Class summary ** - Guide the students to review what they have learned in this lesson, such as observing the same object from different positions may see different shapes, observing different objects from the same position may see the same or different shapes, as well as the correct observation methods. ##5. Reflection on Teaching 1. ** Success ** - The visual teaching effect was better. By letting the students put together the geometric objects and observe them, the abstract knowledge could be turned into an intuitive image, which would help the students establish their concept of space. For example, students could better understand the differences in shapes seen from different directions when they used cubes to assemble geometric objects and observed them. - Group learning played a positive role. When observing, comparing, and exploring different objects from the same angle, group cooperation gave students more opportunities to exchange ideas and cultivate students 'sense of cooperation and expression. 2. ** Inadequacies ** - Some students still had difficulty in abstracting a two-dimensional figure from the observed shape, which might be caused by the difference in spatial imagination. In the future teaching, he could add some targeted exercises, such as letting the students use small cubes to piece together three-dimensional figures according to the given figures observed from three directions, so as to gradually improve the students 'spatial imagination. - The control of teaching time still needed to be further optimized. Sometimes, during the group exploration session, the students 'discussion was too enthusiastic, resulting in a slightly tight time for the subsequent consolidation exercises. It was necessary to better guide the students to complete the task within the specified time. 3. ** Modification measures ** - For students with weaker spatial imagination, more physical models or multi-media animations could be provided to help them better understand the conversion process from three-dimensional to two-dimensional and from two-dimensional to three-dimensional. - During the teaching process, the time of each teaching segment should be arranged more reasonably, and the possible situations of each segment should be pre-set in advance to ensure the smooth progress of the teaching process. At the same time, when the students worked together in groups, they had to patrol and guide them in a timely manner to improve the efficiency of group cooperation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Reflection on Teaching Unit 7 of Mathematics of Grade 5 of Hebei Education Press
1. Teaching should start from life experience, such as using campus activities ("buying kites","changing glass", etc.) as the background, which can help stimulate the students 'childlike interest and encourage them to use the relationship between "yuan, angle" and "meter, decimeter" to smoothly communicate the relationship between decimal multiplication and integral multiplication, making students feel close. 2. The teaching of the significance of decimals and multiplication should be weakened, and the teaching of calculation should be emphasized. Through the creation of life situations, such as calculating the total price of mathematics books (0.52 yuan per book, four books per person), the students could make it clear that the meaning of multiplying decimals by whole numbers was the same as the meaning of multiplying whole numbers. They were both simple operations to find the sum of several identical addenda. 3. The conversion method should be used to teach the multiplication of decimals. For example, in the teaching of 0.72×5, the students should be guided to convert it into a known multiplication formula, let the students experience the conversion process, and learn to use the conversion thought to explore new knowledge. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

How to permeate moral education in primary school mathematics teaching
The primary school mathematics teaching can be carried out in the following aspects: ** I. Penetration in classroom teaching ** 1. ** Excavate the elements of moral education in teaching materials ** - Teachers could dig deep into the moral education content such as mathematical historical materials contained in the textbooks. For example, he introduced the great achievements of mathematics in ancient China. For example, the working people of China could accurately calculate the land area as early as 2,000 years ago. China was the first country to propose the concept of decimals and apply it. Zu Chongzhi was the first person in the world to calculate the value of pi to 7 decimals. Through the explanation of these contents, the students would be able to recognize the great contributions our country had made to mathematics. From there, they would be able to cultivate a sense of patriots and national pride. They would also be able to learn mathematics with a rigorous and realistic attitude, taking the ancient mathematicians as examples and establishing a correct worldview and values. 2. ** Combining knowledge points for moral education ** - When explaining specific knowledge points, moral education should be permeated at the right time. For example, when learning "Pi", he introduced Zu Chongzhi's contribution, which was more than 1000 years earlier than that of the West. He also introduced the outstanding contributions and typical deeds of Chen Jingrun, Hua Luogeng, and other mathematicians in the teaching. He played a role model to promote the learning of subject knowledge, sublimate the students 'patriotic enthusiasm, cultivate the students' self-reliance and tenacious will quality, and encourage them to study hard and serve the motherland. 3. ** Construct a special teaching situation for moral education ** - The concept of moral education was integrated into the teaching situation. For example, when teaching score-related courses, the scores were personified to create a situation, such as arranging seats for 1/2, 3/4, 6/8, and 7/7 (there were only three seats), so that the students could think about the way and reason for arranging seats. After the students were ranked according to their scores, the teachers could infiltrate the moral education concepts of civilized queuing, respecting the old and loving the young, and being polite to others, so that the students could cultivate a good character of civilization and courtesy while mastering mathematics knowledge. ** 2. Penetration of Gratitude Education ** 1. ** The combination of numbers and shapes, gratitude to nature ** - When teaching the area of the rectangular park, the students would discuss the benefits of flowers and trees to life and how to protect the environment, so as to be grateful to nature. 2. ** Create a question to thank your parents ** - For example, in the "shopping" teaching design, through the children's skit performance of buying clothes for their parents, the consumption process was calculated, and the students expressed their gratitude to their parents in the calculation and answer. 3. ** Homework arrangement, gratitude continued ** - He arranged special math homework such as "Draw a picture for Mom" to consolidate his knowledge while permeating gratitude education. ** 3. Infiltrating moral education through mathematics activities ** 1. ** Moral Education in Group Cooperation ** - In group learning, the students 'collective consciousness was strengthened through the successful experience of obtaining group honors. In the process of research learning, teachers guide students to participate in research deeply, guide students to be sincere in teamwork, express accurately, treat different opinions and ideas correctly, learn to communicate and cooperate, refuse negative performance, speak bravely, and express boldly. Teachers give encouragement and praise at the right time, so that the moral cultivation of people can be infiltrated and developed in the mathematics classroom. ** 4. Infiltrating moral education into reality ** - The teacher would integrate life examples into the teaching. For example, when teaching division related knowledge, he would use the case of buying things (such as 20 catties of rice in supermarket A for 50 yuan, 30 catties of rice in supermarket B for 70 yuan, comparing which store is more cost-effective) to let the students use the division knowledge to draw a conclusion, and then guide the students to cultivate the good quality of diligence and thrift. After teaching the third-year "statistics" knowledge, the students would be allowed to practice statistics in real life, excavate the elements in life, and infiltrate moral education thoughts to train the students 'practical application of knowledge. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The Integration and Development of Mathematics Teaching and Labor Education in Primary Schools
The primary school stage was the key period for students to start their labor consciousness. In primary school mathematics teaching, the integration and development of the two were reflected in the following aspects: ** 1. Digging up mathematics materials ** 1. ** Virtue is earned through hard work ** - The primary school mathematics textbooks contained a wealth of mathematical history information. For example, Fang Tianzhang of Nine Chapters on Arithmetic discussed the area algorithm of plane figures and summarized the mathematical achievements of that time. Zu Chongzhi found that pi was between 3.1415926 and 3.1415927. Teachers guided students to understand that these mathematical cultural achievements were the crystallization of the wisdom and sweat of mathematicians. They promoted the progress of human civilization and inspired students to explore and create. - There were many labor education materials in the teaching materials. When learning "The Generation of Numbers", the teacher explained the counting needs of human production labor due to the need to divide things and record things. When learning "The Generation of Scores", the teacher explained that people could not get an integral result when measuring, dividing or calculating in labor, so as to create scores. Digging into this mathematical culture could not only broaden the students 'mathematical horizons, but also allow them to perceive labor and create mathematical culture, cultivating the correct labor and values. ** 2. Carry out practical activities in and out of class ** 1. ** To work hard to think ** - ** In-class practical activities **: Labor education and mathematics teaching both emphasize students 'hands-on operation and cooperative communication skills. Through labor practice and cooperation between students to solve mathematical problems, students would realize the importance of hands-on practice and thinking. - ** Extra-cursory practical activities **: For example, the subject integration homework design activity of Jiangjunqiao Primary School. The theme of the junior students was "Interesting Tangram", which integrated mathematics, labor, and art subjects. The students recognized the geometric figures in the process of making the Tangram and learned to use scissors and other labor tools. The theme of the middle grade students was "Diary of Garlic Sprout Growth", which planted garlic (bean sprouts) and observed the growth situation. The height was recorded by using statistics charts and tables to integrate labor and mathematics. The senior students used "Exploring the Secrets of Paper" as the theme to understand the process of making paper, collect different papers, and use their labor experience to make mathematical three-dimensional drawings with paper. They explored the quality of paper and effectively integrated mathematical and labor literacy. This kind of practical activity allowed students to understand mathematics knowledge, feel the charm of mathematics, solve problems, and grow. At the same time, they improved their hands-on ability and increased their interest in mathematics. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
