Drawing mathematical mind map is a good learning method, which can help students sort out and deepen their understanding of mathematical knowledge. These methods are as follows:

1, determine the theme of your mathematical knowledge, such as "figure and area" and "fractional operation".

2. Write the central theme on paper, such as "Overview of Mathematics Knowledge in the Second Volume of Grade Six".

3. According to the theme, draw branches of the theme, such as "figure and area" and "fractional operation".

4. Under each topic branch, draw secondary branches and list specific knowledge points or topics, such as "rectangle", "square" and "circle" under "figure and area".

5. Under the second-level branch, draw the third-level branch and list more detailed knowledge points or problem-solving methods. For example, under "rectangle", you can list "formula for calculating the perimeter of rectangle" and "formula for calculating the area of rectangle".

6. Connect all branches and sub-branches with wires to show the relationship between them, and rearrange and adjust the branch positions according to the logical relationship.

Drawing mathematical mind map can help students understand and master the structure of mathematical knowledge more clearly and deepen their understanding of the relationship between knowledge points.
