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 down their corresponding knowledge points on white paper, and then use lines to correspond to their secondary themes. In this way, the mind map of Unit 5 of Mathematics in the second volume of Grade Two was completed.

Mind mapping, English is mind mapping, also called mind mapping, which is an effective graphic thinking tool to express divergent thinking? It is simple but effective and efficient, and it is a practical thinking tool.

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.
