1, the relationship between exercise and physical changes: introduce the effects of exercise on various parts of the body, such as cardiopulmonary function, muscle strength, body fat rate, etc. Show the benefits of exercise to the body through simple mathematical examples, such as statistics or percentages.

2. Mathematical model of body change: Introduce how to describe body change with mathematical model. For example, use charts or tables to show the changing trend of height, weight, body mass index and other indicators. This will enable students to understand the extensive application of mathematics in life.

3. Examples of sports and physical changes: through specific sports examples, such as long-distance running, swimming, basketball, etc. Show how exercise affects physical changes. At the same time, some stories of celebrities or athletes can be introduced to increase the interest of handwritten newspapers.

4. Suggestions on health and physical changes: Introduce some suggestions on how to keep healthy, such as reasonable diet, regular work and rest, moderate exercise, etc. Some quantitative suggestions can be given in combination with mathematical concepts, such as average value, percentage and so on.

5. Future trends of sports and physical changes: Discuss the future trends of sports and physical changes. For example, with the development of science and technology, there may be more convenient exercise modes or smarter fitness equipment. Let students use their imagination and think about the possibility of the future.

The making skills of mathematical handwritten newspaper on physical education and physical changes in the fourth grade;

1, determine the theme and content: first determine the theme and content of the handwritten newspaper, such as sports and physical changes. Then, you can collect relevant materials and information from books, internet and other channels.

2. typesetting and typesetting: after collecting enough information, start planning typesetting. Layout can be divided into several parts, such as title, text, illustrations, etc. When typesetting, we should pay attention to the font, size and color of the text, and also pay attention to the position and size of the picture.

3. Highlight the key points: In the process of typesetting, we should highlight the key contents. You can bold or enlarge important titles or paragraphs, or use different colors or fonts to emphasize them.

4. Use charts: When introducing mathematical concepts or statistical data, you can use charts to illustrate. A chart can be a simple histogram or pie chart, or a complex line chart or scatter chart. Using charts can make data more intuitive and easier to understand.

5. Combination of graphics and text: In handwritten newspaper, you can combine pictures and words to explain concepts or describe stories. Pictures can be photos or illustrations related to the theme, or charts or schematic diagrams used to explain mathematical concepts.
