1, determine the main knowledge points: first, determine the main mathematical knowledge points and concepts in primary school, such as numbers and calculations, geometric shapes, fractions and decimals, charts and data.

2. Develop the hierarchical structure: arrange the main knowledge points according to the hierarchical structure. Put the basic concepts at the bottom and gradually expand to more advanced concepts and applications.

3. Establish contact and association: establish contact and association between various knowledge points. Find out the dependence between concepts, such as the progressive relationship between the concepts before and after, and the connection between related knowledge points.

4. Add details and examples: Add details and examples under each knowledge point to deepen the understanding of concepts. It can include specific calculation methods, problem-solving steps, common mistakes and solutions.

5. Mark the key points and concepts: Mark the key points and concepts in the network diagram for students to quickly identify and understand.

6. Review and improve: review and improve the completed network diagram to ensure the consistency and accuracy of knowledge points. You can check the teaching materials or curriculum standards to ensure that there are no omissions or mistakes.

You can use various tools to make a mathematical network diagram, such as mindmanager, online drawing tools or hand-drawing, so that you can choose the appropriate way to make it. The ultimate goal is to organize the knowledge points of primary school mathematics into a clear, orderly and easy-to-understand network diagram to help students better master the basic knowledge of mathematics.

Matters needing attention in making mathematical network diagram

1. Clear and concise: Make sure the structure of the network diagram is clear and easy to read, and avoid too complicated or crowded layout. Every knowledge point or concept should be clearly identifiable and described with concise language and symbols.

2. Normality and accuracy: use correct symbols, symbols and terms to ensure accurate expression. Compared with teaching materials or curriculum standards, maintain unity and consistency.

3. Hierarchical structure, distinct hierarchy: organize knowledge points into hierarchical structure in progressive order, so that students can clearly see the connection and dependence between knowledge points.

4. Contact and association: ensure that each knowledge point is directly connected and associated with other related concepts and knowledge points. Use arrows, lines and other forms to express the relationship between knowledge points.

5. Add details and examples: Add necessary details and examples under each knowledge point to enrich understanding and application. These details can be specific calculation steps, formulas, examples, etc.

6. Use graphics and colors: If possible, consider using graphics, charts or colors to enhance the visualization of the network diagram. This can help students better understand and remember knowledge points.

7. Review and feedback: After the production is completed, review and accept feedback from others. Ensure the accuracy, completeness and readability of the network diagram.

8. Update and maintenance: With the change and progress of teaching content, update and maintain the mathematical network diagram regularly to reflect the latest teaching requirements and knowledge system.
