1, determine the central theme: determine the central theme of Unit 6, namely "circumference and area of a circle". List knowledge points: list the knowledge points learned in this unit, such as "circumference of a circle", "area of a circle" and "sector".

2. Sort out the relationship: according to the relationship between knowledge points, connect them to form a preliminary mind map. Details: Every knowledge point is very detailed, for example, the circumference can be subdivided into definition, formula and application.

3. Beautify style: Beautify mind maps according to personal preferences and requirements, such as using different colors, fonts and line thicknesses. Save and export: save or export the prepared mind map for easy viewing and use at any time.

The Mind Mapping Function of Mathematics

Promote the integration and classification of thinking: mind map can integrate and classify various mathematical knowledge and concepts, and help students establish a complete mathematical knowledge system. Through mind mapping, students can better understand the connections and differences between mathematical concepts, and sort out and summarize various knowledge points of different categories.

Improve problem-solving ability: Mathematical mind map can help students better understand mathematical problems and find the essence and laws of problems. In the process of solving problems, mind mapping can help students break down problems into smaller parts, thus making it easier to get ideas for solving problems. At the same time, mind mapping can also help students better organize the problem-solving process and reduce the occurrence of mistakes.

Enhance the fun of learning: Compared with the traditional linear note-taking teaching method, the images and colors of mind map can stimulate children's interest and imagination, and can effectively help children improve their enthusiasm for learning and reduce stress.
