You can draw according to the knowledge in unit 123. Before the reform edition, the first volume of Grade Four of Beijing Normal University had no unit 123, that is, knowing more numbers, lines, angles and multiplication, and then designing mind maps in the form of tables, which can be expressed by flowcharts or other graphics.

Then you can add the relevant knowledge in the unit, you can add the basic knowledge, you can also add the key knowledge of the unit. When drawing a mind map, the most important thing is to add the key knowledge, and the decoration can be less, as long as it is slightly modified.

The most important thing is to make the picture clear and let the students see it more clearly. Therefore, the above is a drawing method of Unit 4 123, Volume 1, North Fourth Edition, and the drawing process of a mind map.

Introduction to mind mapping:

English is a mind map, also known as mind map, and it is an effective graphic thinking tool to express divergent thinking. It is simple, 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.

Mind mapping makes full use of the functions of the left and right brain and the laws of memory, reading and thinking 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. Therefore, mind mapping has a powerful function of human thinking.

Mind mapping is a visual way of thinking. We know that radioactive thinking is the natural way of thinking of the human brain. Every kind of information that enters the brain, whether it is feelings, memories or ideas-including words, numbers, symbols, smells, food, lines, colors, images, rhythms, notes and so on. -It can be a thinking center, where thousands of joints radiate outward.

Each joint represents a connection with the central theme, and each connection can become another central theme, and then thousands of joint points radiate outward, showing a radioactive three-dimensional structure, and these joint connections can be regarded as your memory, just like neurons in the brain, and are your personal database.
