1. Confirm the central theme. Draw a rectangle in the middle of the blank space of the white paper. This rectangle is the central theme of our mind map. After drawing, fill in our topic: multiplication in table (1). Of course, you can also write the theme first and then draw a rectangle.
2. Construct a secondary theme. The content of multiplication in the table (1) can be divided into the following parts: a preliminary understanding of multiplication; 2~6 multiplication formula; Multiply, add, multiply and subtract; Solve problems; The four modules are arranged at a certain distance, because when filling in the content, the distance is too close, which will affect the output.
3. Improve the content of the brain map, classify it according to the secondary themes, write their corresponding knowledge points on white paper, and then use the connection lines to correspond to their respective secondary themes, so that the second-grade mathematical mind map is completed.
The above is the drawing method of mind map in the second volume of second grade mathematics.
