The Discoveries and Thoughts of Mathematics Practice in Primary Schools
The following are some findings and thoughts about elementary school mathematics practice: ** 1. Teaching materials and knowledge imparting ** 1. ** Three-Dimensional Image Awareness ** - In books like Elementary Mathematics Practice, by explaining the characteristics of cuboids and cubes to primary school students, it could deepen their understanding of three-dimensional graphics. This kind of theoretical explanation was the basic part of mathematics practice. For example, students could learn about the number and nature of the faces, edges, and vertexes of cuboids and cubes. 2. ** Teaching Material Version Knowledge Essence ** - For example, in the second volume of the seventh grade's mathematics, Practice and Exploration II (East China Normal University edition), it focused on teaching materials and knowledge. Taking the problem of finding the area of a small rectangular floor tile with eight identical small rectangular floor tiles combined into a large rectangular pattern as an example, this reflected the further cultivation of mathematical ability on the basis of primary school mathematics practice. By setting unknown numbers, finding equivalent relations, solving equations, and other steps, it was helpful to improve students 'logical thinking and problem solving ability. ** 2. Teaching methods and activities ** 1. ** Game Teaching ** - In the teaching of Elementary Mathematics Practice, the teacher and the students played games face-to-face to deepen the students 'understanding of the difference between cuboids and cubes. This kind of game teaching method made abstract mathematical knowledge concrete, allowing students to learn in a relaxed and happy atmosphere, increasing students 'participation and interest in learning. 2. ** Comprehensive Practice Activity ** - In the mathematics practice activities of Huiwang Central Primary School in Baqiao District, different grades carried out various forms of activities. - Through the practice of observing objects, first-year students were allowed to personally experience that "when observing objects from different positions, the shapes they see may be different." This helped to cultivate students 'spatial concepts and observation skills. - The second year students made the direction board, which not only trained their hands-on ability but also deepened their understanding of the "plane direction". - The third grade's paper-cutting activity was to cut out axis-symmetrical figures, accumulate perceptual knowledge of axis-symmetrical figures, and improve hands-on practical ability. - The fourth-graders made a "moving" digital sequence table. Whether it was in the form of a drawing or making a counter, it would allow the students to have a deeper understanding of digital concepts. - The fifth grade integrated mathematics knowledge into the map, and the sixth grade used mind maps to organize mathematics knowledge. These activities combined mathematics knowledge with practical application or knowledge sorting from different angles to improve students 'comprehensive mathematics accomplishment. ** 3. Connection between Mathematics and Life ** 1. ** National Day Themed Practice Activity ** - In Baqiao District Huiwang Central Primary School's National Day themed mathematics comprehensive practice activity, all grades combined mathematics and patriotic topics. For example, the first graders looked for numbers in their daily lives, the second graders looked for the mystery of numbers in the national flag, the third graders used the data from the Long March to make tabloids, the fourth graders used paintings to express digital China, the fifth graders used mathematical eyes to look at maps, and the sixth graders used "numbers" to describe the changes in China. These activities fully demonstrated the close connection between mathematics and life. It allowed students to discover mathematics in their daily life and use mathematical knowledge to interpret the phenomena in their daily lives, improving their ability to apply mathematics. 2. ** Practice on Understanding RMB ** - In the extra-cursory practice of understanding RMB in the first grade, students were familiar with the mathematical knowledge related to RMB through the conversion, calculation and application exercises of RMB. For example, one 100 yuan note could be exchanged for 100 1 yuan notes, 20 5 yuan notes, 10 10 yuan notes, etc. This was also the embodiment of the close integration of mathematics and life practice, so that students understood the practicality of mathematics in daily life.

Thoughts on the New Mathematics Assessment in Primary Schools
" Thoughts on the New Mathematics Assessment for Primary Schools " The evaluation and suggestions in the new primary school mathematics curriculum standard brought many aspects worth thinking about. I. Guiding nature of evaluation The new curriculum standard emphasized the role of evaluation in educating people. This meant that the evaluation was no longer just about the student's knowledge mastery, but more about the guidance of the student's all-round development. Traditional evaluations often focused on results, such as students 'test scores. But now, the evaluation had to run through the entire process of students 'learning, from the acquisition of knowledge and skills, to the application of processes and methods, to the cultivation of emotional attitudes and values. This would help to change the phenomenon of purely pursuing scores in teaching and encourage teachers to focus on cultivating students 'multi-dimensional qualities in the teaching process, such as cultivating students' positive learning attitude, interest in mathematics, and the spirit of exploration. II. The Pluralism of Evaluation 1. multiple subjects The main body of evaluation changed from being singular to being diverse and interacting. In the past, the evaluation was mainly carried out by teachers. Now, it was necessary to guide students to evaluate themselves and treat others correctly and objectively. This change helped to cultivate students 'self-reflection ability and critical thinking. When students participated in self-evaluation, they could understand their own learning process and results more deeply, identify their own strengths and weaknesses, and make targeted improvements. At the same time, the mutual evaluation between students could also promote mutual learning and learning, and enhance communication and cooperation between students. 2. Diverse content The evaluation not only focused on knowledge and skills, but also covered the student's progress in the learning process. It involved knowledge, skills, emotions, values, and many other fields. This required teachers to observe the students in the teaching process, such as paying attention to the students 'performance in group cooperative learning, such as whether they actively participated in discussions, whether they respected the opinions of others, and so on. It was not just about whether their answers to mathematical knowledge were correct. This kind of multi-content evaluation could reflect the student's learning status and overall quality more comprehensively. Third, the motivation and development of evaluation 1. incentive function The development evaluation focused on the comprehensive evaluation of the students after a stage, and its incentive function was more prominent. By discovering the students 'progress in the learning process in time and giving recognition, it could stimulate the students' motivation to learn. For example, for students who had unique insights in mathematical thinking but were slightly weaker in computational ability, if the teacher could recognize the brilliance of their thinking in the evaluation, it would encourage them to continue to maintain innovative thinking and encourage them to work hard to improve their computational ability. 2. development function The purpose of the evaluation was to help students formulate improvement plans and promote better development. This made the evaluation an important driving force in the student's learning process. Teachers could provide students with personal learning suggestions based on the evaluation results, guide students to constantly adjust their learning strategies, and gradually achieve all-round development. This kind of evaluation for the purpose of development broke the traditional method of simply categorizing and tagging students, allowing each student to continuously improve on their own foundation. In summary, the new curriculum standard primary school mathematics evaluation proposal brought a new perspective and concept for teaching evaluation, prompting teachers to update the evaluation concept and adopt a more scientific, comprehensive, and diverse evaluation method, so as to better promote the comprehensive development of students. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

For example, when explaining teaching content, classroom interaction, assignment and evaluation, they must consider the needs of all students. 2. ** Establishing a democratic and equal emotional atmosphere ** - Teachers had to ensure that they had good feelings and emotions, because this had a direct impact on the establishment of the emotional atmosphere in the classroom. Through a democratic and equal atmosphere, students 'interest in learning mathematics was stimulated, and their creativity and imagination were encouraged to improve their enthusiasm and initiative in learning. To be specific, teachers should ensure democratic teaching in their teaching, encourage all students to actively participate in classroom teaching, and encourage students to express their views and understanding. 3. ** Use a scientific and reasonable evaluation mechanism ** - The assessment was mainly based on encouragement, and the students 'learning was evaluated in a timely manner to maintain the students' learning enthusiasm and self-esteem. This kind of evaluation method could adjust and optimize the students 'cognitive behavior and produce positive emotional results. ** 2. Teaching methods ** 1. ** Teaching Method ** - Teachers use verbal language to describe situations, narrate facts, explain concepts, prove principles, and clarify laws. This was a common teaching method that could systematically impart knowledge to students. 2. ** Conversation (Answer)** - Through the conversation between teachers and students, they could spread and learn knowledge. The teacher guides the students to use their existing experience and knowledge to answer the questions raised by the teacher, so that the students can obtain new knowledge or consolidate or check the knowledge they have learned. 3. ** Demonstrating Method ** - The teacher showed the real object or the model of the real object to the students for observation, or through demonstration experiments, with the help of modern teaching methods, so that the students could obtain new knowledge. 4. ** Class Discussion Method ** - (The reference materials are not detailed, but it is generally to organize students to discuss a certain mathematical problem or knowledge point to promote students 'in-depth understanding of knowledge and cultivate students' thinking ability and cooperation and communication skills.) 5. ** Hands-on operation method ** - (The specific operation was not mentioned in detail, but it can be speculated that students can learn mathematical knowledge through hands-on practice, such as making mathematical models, which helps to improve students 'hands-on ability and intuitive understanding of mathematical knowledge.) 6. ** Teaching methods related to migration guidance ** - Teachers should analyze the knowledge structure of the teaching materials and the connection between the old and new knowledge, guide the students to work hard on the connection points of the old and new knowledge, let the students go from the known to the unknown, from the shallow to the deep, and make the new lesson not new and difficult. 7. ** Prospective guidance related teaching methods ** - The teacher described the prospects of the problem, guided the students 'interest, and made the students clear the direction of their thinking. Then, the students were asked to study the ways and methods to achieve this prospect. 8. ** Demonstrating teaching methods ** - According to the students 'cognitive level, guide the students to develop to a higher level in terms of knowledge and ability. After listening to the lecture, not only can the students solve doubts, but they can also be inspired in observation, analysis, and thinking. ** 3. Connecting with life ** - In order to bring mathematics to life, one had to consider the abstract and theoretical characteristics of mathematics itself, and increase students 'interest in mathematics through certain strategies. This was also a part of the research and practice of teaching methods. Although the reference materials did not elaborate on specific teaching methods, it hinted that teaching should pay attention to the connection between mathematics and life, so that abstract mathematical knowledge could be more intuitive and easy to understand. ** 4. Penetration of mathematical thinking methods ** - Some books summarized the teaching methods of primary school mathematics from the perspective of mathematical thinking, and there were related teaching cases. Teachers could combine mathematical knowledge and mathematical ideas, transfer them to examples and exercises in textbooks, and then apply them to consolidating exercises. They could even transfer them to secondary school mathematics learning. Thus, they could permeate mathematical ideas into their teaching for a long time, teach students how to learn, how to think, and improve their mathematical attainment. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

They needed to deepen their understanding through practical operations and life experiences. ** 4. Practice content and process ** 1. ** One day of my time to produce tabloids ** - After the students learned the 24-hour Timekeeping Method, they produced a time tabloid with the theme of "My Day". They recorded the corresponding time of each activity from waking up to sleeping, and used a paintbrush to describe the colorful life of the day. For example, waking up at 7:00 am, attending classes from 8:00 am to 12:00 am, having lunch at 12:30 am, and so on. - In this process, the students needed to accurately use the 24-hour timing method to indicate the time, and reasonably arrange the activities of different time periods in the tabloids. This not only consolidated their knowledge of timing, but also allowed them to become observers of life and think about how to arrange their time reasonably. 2. ** Food shelf life survey ** - The students turned into little food investigators and conducted safety investigations on the food at home. He checked the production date and shelf life of the food, and then judged whether the food had expired. For example, by calculating that the production date plus the shelf life had not reached the date of the day, so it did not expire. - This activity involved simple date calculations, allowing students to combine mathematics knowledge with food safety issues in their family lives and experience the importance of mathematics in real life. 3. ** The mystery of the calendar ** - The students made a birthday calendar, and in the process, they discovered small patterns and secrets about time. For example, some students realized that the first day of each month was not necessarily a Monday, and the calendar records began from Sunday. - They also delved into the calendar to observe which months had the same "days of the week". They made bold guesses and verified their ideas through mathematical calculations. This would help students understand the relationship between year, month, and day and improve their mathematical thinking ability. ** 5. Practice results and gains ** 1. ** Knowledge and Skills ** - The students were more familiar with the 24-hour timekeeping method and could accurately switch between the ordinary timekeeping method and the 24-hour timekeeping method. - He had a deeper understanding of the concept of year, month, and day, including the number of days in the big month, small month, ordinary year, and leap year, as well as the relationship between the days of different months and the week. - He learned simple date calculation, such as calculating the shelf life of food and determining the order between two dates. 2. ** Ability and Quality ** - Through the production of time tabloids and a calendar, the students 'hands-on ability was trained, and they were able to display their mathematical thinking results in the form of charts. - In the process of investigating the shelf life of food and exploring the rules of the calendar, the students 'observation, analysis, and problem solving skills were improved. They learned to discover mathematical problems in their lives and use what they learned to solve them. - The entire practical activity stimulated the students 'interest in mathematics learning. It made them feel that mathematics was not just boring numbers and formulas, but a subject that was closely related to life and full of fun. 3. ** Emotional attitude ** - The students strengthened their concept of time in the process of practice, understood the preciousness of time, and developed a good habit of cherishing time. For example, through the creation of the "My Day" tabloid, they realized the importance of managing their time properly. - When students successfully discovered the pattern in the calendar or correctly judged whether the food had expired, they would gain a sense of accomplishment, which would enhance their self-confidence and increase their enthusiasm for mathematics learning. ** 6. Practice summary and reflection ** 1. ** Success ** - The content of the practical activities was closely related to the reality of life, starting from the familiar life scenes of the students, such as the daily life schedule, family food, etc. This greatly increased the participation and enthusiasm of the students. - Various forms of practice, such as producing tabloids, conducting investigations, and exploring laws, met the needs of students with different learning styles, allowing each student to find their own interest and space to develop in practice. - Through practical activities, the students 'mastery and application of mathematical knowledge were effectively improved, and the expected teaching goal was achieved. 2. ** Inadequacies and improvement measures ** - In practical activities, some students might encounter difficulties in exploring more complicated tasks such as the calendar due to their weak foundation or poor thinking ability. In the future, he could provide more guidance and individual tutoring for these students. For example, he could design layered tasks so that each student could gain something within their own ability. - Although practical activities focused on students 'independent exploration, there were relatively few opportunities for group cooperation. In the future activities, some tasks that required group cooperation could be added, such as making the annual calendar in groups, so that students could learn from each other and improve their teamwork and communication skills. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Thoughts on the practice of garbage classification for primary school students
After participating in the garbage sorting practice, primary school students might have the following thoughts: ** I. Deepen your understanding of garbage classification ** 1. ** A detailed understanding of the classification ** - In the past, they might only know the simple classification of recycled and non-recycled. After practice, they found that garbage classification could be divided into many types. For example, some recycled garbage could be recycled into new resources, which not only protected the environment but also saved resources. Some garbage that was harmful to the environment would cause secondary pollution if placed randomly, and it was difficult to remove harmful components even if it was processed collectively. 2. ** The gap between theory and practice ** - Although he had learned about garbage sorting a long time ago, he had never applied it in practice before. He realized that knowing but not doing it was very harmful. As the hope of the future of the motherland, if he did not practice it himself, it would be difficult to ask others to adhere to the concept of garbage classification. ** 2. Increase your sense of responsibility ** 1. ** Awakening to self-action ** - He realized that he couldn't let the garbage sorting practice remain as a formality. He had to sort the garbage properly when he dealt with it and pick up the garbage on campus in time. 2. ** Affect others 'sense of mission ** - Realizing that he had the responsibility to influence the people around him to call for more people to carry out garbage sorting, he had to cultivate the habit and sense of responsibility of garbage sorting, and when he did not sort the garbage, he should feel guilty. Only in this way could he be considered to have successfully promoted garbage sorting. ** 3. Observation and Reflection on the Social Level ** 1. ** Thoughts on Cleaning Work ** - When they saw the cleaners mix the sorted garbage into the garbage truck, they would think about how to provide the cleaners with the concept of effective garbage sorting, such as setting up a partition in the garbage truck and marking it, otherwise the previous sorting work would become meaningless. 2. ** The expectation of society as a whole ** - He hoped to implement garbage sorting on everyone and realize that environmental protection was not a matter of one person or a small group of people, but a matter of everyone's joint efforts. Only by everyone's participation could a good garbage sorting effect be achieved and the environment become better. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

How to permeate educational thoughts into science teaching in primary schools
The infiltration of ideology education in primary school science teaching can be started from the following aspects: 1. ** Cultivating scientific attitude through exploratory experiments **: - Teachers could arrange exploratory experiment assignments, such as setting different experimental conditions during the lesson of Seed Germination, such as exposing the seeds to waterless air, in an environment with suitable temperature and humidity, in water without contact with air, in a humid low temperature environment with air, etc. - Students were encouraged to create their own experimental conditions, boldly guess the external conditions needed for seed development, and then verify it independently. They would make records every day to cultivate the students 'scientific spirit of being brave in exploration, fearless of setbacks, and daring to be innovative, as well as their scientific attitude of seeking truth from facts. 2. ** Cultivating social responsibility through life-oriented teaching methods **: - Link science curriculum knowledge with real life, such as integrating green environmental protection concepts into teaching. - To guide students to form a sense of social responsibility such as caring for nature, cherishing life, cherishing resources, and caring for the environment. To help students understand the relationship between science and technology and society, and to lay the foundation for a healthy lifestyle. 3. ** Based on the phenomenon of life to trigger thinking **: - With the phenomena in life as the carrier, it guides students to construct their own ideas to solve problems when they face interesting phenomena and problems, and cultivates students 'thinking ability. 4. ** Cultivate scientific spirit and strengthen critical thinking ability **: - In scientific experiments, students were encouraged to take the initiative to make guesses, think independently and explore, and stimulate curiosity and the spirit of exploration. 5. ** Pay attention to students 'emotional experience and strengthen their ethical awareness **: - Guide students to reflect on and feel the ethical, moral, and social issues in the process of scientific inquiry, and enhance their sense of social responsibility and spirit of responsibility. For example, in the "candy power generation" experiment, students were allowed to understand the principle of power generation and discuss the recycling of candy waste to cultivate environmental awareness; In the "scientific purification of water" study, students independently designed and manufactured water purifiers with ethical awareness such as "clean water cannot be wasted"; Through the investigation and research of new products of science and technology, the impact of science and technology on life and the values and risks behind it were discussed to awaken students 'thinking about aesthetics and responsibility. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What does the ability to transform thoughts in primary school mathematics mean?
In primary school mathematics, the ability to transform thoughts referred to the ability to turn a mathematical problem into a solvable problem when it could not be solved directly. This ability was reflected in many aspects: 1. ** Problem Form Conversion **: Transform an unsolvable problem into a manageable problem. For example, when solving the volume of an irregular stone, because its shape was irregular and could not be directly calculated by the volume formula of the three-dimensional figure, it could be transformed into a volume problem of a known shape (such as a cuboid) to solve. For example, if an irregular stone was immersed in a rectangular water tank, the volume of the irregular stone would be converted into the volume of the rising water by observing the height of the water surface. 2. ** Complicated Problem Reduction **: Transform a complicated problem into a simple problem. For example, in the mathematics teaching of senior primary school students, when deducing the area of a quadrilateral, the students would transform the area calculation of the quadrilateral that they had not learned into the area calculation of the rectangular area that they had learned; when deducing the area of a triangle, they would transform it into a quadrilateral; when deducing the area formula of a circle, they would transform it into a rectangular; when deducing the volume formula of a cone, they would transform it into a cylinder, and so on. 3. ** Familiarizing unfamiliar questions **: Transform unfamiliar questions into familiar ones. For example, in the calculation of multiplying two or three digits by one digit, the whole ten or hundred digits multiplied by one digit would be converted into table multiplication, and then the corresponding number of zeros would be added to the end of the product. This was to solve the problem by transforming the unknown and unfamiliar multiplication into the known and familiar table multiplication. 4. ** Conversion between different operations **: Conversion between operations can be performed as needed during the calculation process. For example, when dividing, one could convert a fraction division into an integral division. When calculating multiplication, one could convert a certain formula into a form that could be solved by the distribution law of multiplication. Or when comparing the size of two formulas, one could directly obtain the size relationship through reasonable conversion to avoid complicated calculations. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
