1, determine the theme of mind map. In this example, the themes are space vectors and solid geometry.

2. Choose the right paper and color. Choose a piece of A4 or A3 paper, and the color can be determined according to personal preference.

3. Write the theme in the center of the paper. In this example, the space vector and solid geometry can be written in the middle.

4. Add the main branch. Add some main branches around the topic, which can represent the main concepts or sub-topics of space vector and solid geometry. Such as space vector, solid geometry, application, etc.

5. Add a secondary branch. Under each main branch, add some secondary branches, which can represent more specific concepts, formulas or application examples. For example, you can add secondary branches under the space vector, such as the concept of vector, the operation of vector and the coordinate representation of vector.

6. Add details. Under each secondary branch, you can continue to add more detailed branches, such as the definition of vector, the module length of vector, unit vector and other detailed branches under the concept of vector.

7. Use graphics or pictures to explain concepts. Adding graphics or pictures to mind maps can better explain concepts and help memory. For example, you can add a line segment under the modulus length of the vector to indicate the length of the vector.

8. Use colors and codes to distinguish different themes and levels. Different colors can be used to represent different themes or sub-themes, and different fonts or sizes can be used to represent different levels.

9, check and improve the mind map. After completing the mind map, check whether it contains all important concepts and details, and make sure its logical structure and hierarchy are clear.

Mathematical space vector and drawing skills of solid geometry mind map;

1. Hierarchical structure: Mind mapping should adopt a hierarchical structure to ensure that it starts from the central theme and develops layer by layer, covering all relevant concepts and knowledge points. For each level, you can add different levels of branches to represent different levels of concepts and formulas.

2. Symbolization: In mind map, symbols and marks can be used to represent different mathematical concepts and objects. For example, the vector symbol → can be used to represent the vector, and brackets can be used to represent the coordinate system on which the vector depends.

3. Graphics: Graphics are an important means to make mind maps more intuitive and vivid. Graphics can be used to represent the relationships and processes between mathematical concepts. For example, arrows are used to represent the direction of vectors, and line lengths are used to represent the module length of vectors.
