The drawing method of thinking-guided composition in unit 123 of mathematics in the fourth grade of primary school can start with the knowledge points you want to draw in advance, and then draw with paper and pencil, or draw with computer software, that is, draw a shopping guide map with computer drawing software.

For example, the first unit is divided into the practical application of angle line, the measurement of angle is the second-level topic, and then the first-level topic is angle and line, and then the relevant knowledge of angle and line can be supplemented. Points will be classified by angle measurement, and then these knowledge points will be taken as three-level topics to make a diagram in the form of divergence.

Another diagram is that you can make a flowchart, take the top knowledge as the most general knowledge, and then refine it. So the above is the drawing method of thinking-guided composition in Unit 123 of the fourth grade mathematics in primary school.
