1, determine the central theme:

In the first step of drawing a mind map, you need to determine the central theme. In this case, the central theme can be "Digital World".

2. Add the main branch:

Starting with the central theme, you can start adding main branches. These should be first-class topics, which can include: reading and writing numbers, sequence of numbers, comparison of numbers, operation of numbers, etc.

3. Add a secondary branch:

Under each major branch, you can add secondary branches. These can include the classification of numbers, units of numbers, addition and subtraction of numbers, multiplication and division of numbers, etc.

4. Use graphics and colors:

Using graphics and colors can make your mind map more attractive. You can use different colors to represent different themes or branches, while graphics can be used to represent various mathematical concepts.

The importance of mathematical mind map;

1, improve learning efficiency:

Mind mapping uses images, colors, lines and keywords to form knowledge focus and knowledge network, and presents, labels and arranges mathematical knowledge in the form of images, which improves students' memory and understanding ability. Using mind map, students can understand the relationship between mathematical concepts and knowledge points more intuitively.

2, stimulate thinking and creation:

Mind mapping is a kind of thinking tool aimed at promoting thinking stimulation and thinking arrangement. Through the divergent and multidimensional characteristics of mind map, students can associate and innovate in the learning process, find and solve problems. At the same time, the graphical characteristics of mind map are also helpful to stimulate students' interest in learning and creative thinking.

3, improve the quality of thinking:

Mind mapping is a kind of brain instruction that can make people thinking visualization. By using mind map, students can better understand and master mathematical concepts and knowledge points, and improve the clarity and organization of thinking. In addition, the divergent characteristics of mind map are also helpful to cultivate students' divergent thinking and creative problem-solving ability.
