The construction mode of mind map is to determine a central theme, lead out sub-themes, and then divide the sub-themes into levels. Let's take a knowledge point of primary school mathematics as an example and draw a mind map. Use the simplest language to determine the mathematical theme to be drawn. Let's take the measurement of angle as an example. An angle is a figure composed of two rays drawn from a point. So let's learn about rays first.

Draw line segments and straight lines with rays and compare their similarities and differences. Let's first mark the key words on the mind map about the important knowledge points of angle. In this mind map, we know that the definition of light comes from angle, and we can draw the relationship line between angle and light, which is convenient for us to connect knowledge points in series.

The importance of mind mapping

First of all, we all know that the beginning of the third grade of primary school is a watershed in primary school mathematics learning. From the third grade, students should not only pay more attention to mathematics learning and problem-solving methods, but also improve their mathematical thinking and thinking ability. The application of mathematical mind map can make children have more associations between knowledge points and open up thinking space. Let children's understanding of knowledge rise to a higher level.

Secondly, the use of mathematical mind map can help students to show some abstract mathematical problems in a more intuitive image, and it is not so difficult to understand.

I have also mastered the skills of division calculation from the law, which makes the calculation more convenient, helps students get rid of abstract concepts, and enhances everyone's self-help analysis ability and independent thinking ability. This is indeed one of the necessary contents to improve knowledge and skills in the process of mathematics transition in grade three.

Third, these intellectual mind maps make the important and difficult points of each chapter more prominent. In the process of mathematics learning, I should not only keep in mind the basic concepts, methods and skills, but also analyze and summarize the key and difficult contents in each chapter and allocate the learning time reasonably. Only by breaking through the difficult parts can you master the learning skills to solve more practical problems.

Finally, and more importantly, the learning mode of knowledge mind map can stimulate students' interest in learning mathematics. Compared with the previous learning form that lists the knowledge points one by one, this kind of knowledge mind map takes a lot of time to remember. If expressed in this form, it can attract students' attention.
