1, the role of mind mapping
In the first and second grades, many parents have developed a good habit of previewing and reviewing for their children. In the third grade, children can exercise their habits in another way, such as making mind maps, consolidating the knowledge points they learn every day and improving their memory.

The main knowledge of Unit 6 of Mathematics in Grade Three is the multiplication of two digits. As the center of mind map, you can draw a favorite graphic representation. The five contents of this unit are represented by branches, and each branch is subdivided into several important knowledge points. As a mind map, the main contents and steps are as follows:
We use the simplest language to determine the mathematical theme to be drawn, taking "angle measurement" as an example.
An angle is a graph composed of two rays drawn from a point, so it starts from the ray.
Draw line segments and straight lines with rays and compare their similarities and differences.
The angle of marking key knowledge points on the mind map.
3. Other drawing methods
Hand-drawing: We can make mind maps by hand-drawing. First, we need to take out a piece of white paper and some pens of different colors. Draw a picture in the middle of the paper, fill in the main contents of the whole picture with "Mathematics in Grade Three" as the central theme, and fill in the contents according to the central theme.
Computer software production: download, install and run with MindNow or use the online version to enter, and click "New" to select the appropriate map structure; Take the "mind map" structure as an example, double-click the central theme to change the content to "Grade Three Mathematics", and then fill in the content with this sub-theme.
Mind mapping uses the skills of paying equal attention to graphics and texts, showing the relationship between topics at all levels with hierarchical diagrams of mutual subordination and correlation, and establishing memory links between topic keywords, images and colors. It makes full use of the functions of the left and right brains to help people develop in a balanced way between science and art, logic and imagination, thus opening up the infinite potential of the human brain.
