Preparation tools: prepare a piece of white paper or draft paper, pencils and markers specially used for drawing. You can draw a preliminary mind map with draft paper first, and then draw the final version with white paper.

Topic selection: determine the mathematical topics for drawing mind maps, such as geometry, algebra, fractions, etc. Choose appropriate graphics and symbols according to the theme to make the mind map more intuitive and clear.

Central concept: write the central concept or core question in the center of the mind map and highlight it with a circle or box. The central concept can be the key content or key concept of this chapter.

Branch extension: starting from the central concept, draw several main branches, representing important knowledge points or sub-concepts related to the central concept. Each branch and center concept can be connected by curves and straight lines.

Refine branches: further divide sub-branches on each main branch to express more specific related concepts or knowledge points. You can use different colors of pens or different shapes of graphics to distinguish different levels of branches.

Association line: Use arrows or straight lines to connect related branches and show their logical relationship or dependency. This helps to clarify the relationship and order between concepts.

Symbols and figures: use symbols, figures or special marks to express specific concepts or relationships in mathematics, making mind maps more readable and understandable. For example, triangles are used to represent theorems, plus signs are used to represent formulas, and so on.

Color application: using different colors to distinguish and emphasize can improve the visibility and aesthetics of mind maps. Try to choose bright and contrasting colors to make the mind map more eye-catching.

About mind mapping

1, structure: Mind maps usually start with a central theme or core concept, and then expand through branches and connectors to form a tree structure. The relationship between the central theme and branches can be hierarchical, classified, causal and so on.

2. Symbols and graphics: Mind maps use simple graphics and symbols to express different concepts and relationships. For example, circles or boxes represent topics or keywords, branches represent related concepts or sub-topics, and arrows represent connections and relationships.
