1, combing the knowledge structure: systematically classify the knowledge structure according to the contents of each chapter in the textbook, first list the knowledge structure into a flow chart, and list the contents of each chapter and the corresponding knowledge points.

2. Refine each knowledge point: On the basis of the flow chart of knowledge structure, expand the contents of each chapter and the corresponding related knowledge points one by one to form a more detailed knowledge structure.

3. Explain with words and charts: In order to better explain the content of mind maps, you can add some words or related schematic diagrams to each knowledge point for targeted display.

4. Embody the logic and operability of mathematics: When making mind maps, we should pay attention to embody the logic and operability of mathematics, and use corresponding symbols and graphics to express the basic applications and methods in thinking.

5. Emphasize the key points and difficulties: For the heavier and more difficult knowledge points, you can use psychological memory methods, such as colors and geometric shapes, to help students better remember and understand.

6. Backup and proofreading: After the mind map is made, it should be backed up and proofread to prevent the wrong content from being distributed to other students' mind maps.

Finally, students can stick the mind map on their desks, consult it at any time, and use it as an important reference for lesson preparation, so as to summarize and reflect, so as to better improve their mathematical thinking and understanding ability.

Matters needing attention in drawing mind map

1. Sorting out key knowledge points: When making a mathematical mind map, we should first sort out the key knowledge points in the textbook and organize them according to the logical relationship of the knowledge points.

2. Plane arrangement content: In the mind map, the knowledge points at the same level should be arranged at the same level, and the font size and shape should not be different.

3. Graphical representation: various symbols and charts can be used to represent the relevant relationship of knowledge, such as arrows and brackets.

4. Pay attention to the standardization of format: while making mind maps, we need to pay attention to the standardization, size and color of fonts. Too small and crowded fonts will affect the reading effect of mind maps.

5. There should be correlation between related knowledge points: there should be correlation between adjacent knowledge points, and related lines can be established according to these correlations to make the mind map more intuitive and clear.

6. Clearly highlight the key points: some knowledge points with special notes or labels should be highlighted in the mind map to make it easier for students to find the key points and key knowledge.
