1. Determine the central theme: open a mindmanager (such as XMind, MindNode, etc.). ) and enter the seventh unit of mathematics in the center. This topic is the backbone of your mind map and represents the main content you want to discuss.

2. Add subtitle: around the trunk, add some subtitles related to the trunk. These sub-topics can be concepts, formulas or problem-solving methods that you think are important. For example, understanding numbers, addition and subtraction, length and weight are all possible topics.

3. Further refine sub-topics: For each sub-topic, you can continue to add more detailed content. For example, under the theme of number understanding, you can refine it into integer understanding, fraction understanding, decimal point understanding and so on.

4. Use colors and pictures: In order to make mind maps more attractive, you can use different colors to mark different topics or sub-topics. You can also add some pictures or icons to better explain and remember some concepts or formulas.

5. Self-reflection and revision: After completing the preliminary mind map, take some time to check and reflect. See if there is anything missing, or if there is anything that needs further explanation or refinement. Then make the necessary changes.

The purpose of making the mind map of unit 7 of mathematics in the first volume of the third grade;

The purpose of making the mind map of Unit 7 in the first volume of Grade Three Mathematics is to help students better understand and master the knowledge points of this unit.

Mind mapping can summarize and sort out the knowledge points of this unit through graphics and words, and help students clearly understand the connections and differences between various knowledge points. In this way, students can better master the knowledge system of the unit and improve the learning effect.

Mind mapping can also help students better understand and remember these knowledge points by highlighting the key points and difficulties of the unit through colors, shapes and pictures. At the same time, mind mapping can also link the knowledge points of this unit with real life, and help students to better apply what they have learned and solve practical problems.

The purpose of making the mind map of Unit 7 of Mathematics in the first volume of Grade Three is to cultivate students' thinking ability and learning methods. Mind mapping is a kind of thinking tool, which can help students organize and express their ideas better in the learning process and improve learning efficiency. At the same time, by using mind mapping, students can better master learning methods and skills and lay a solid foundation for their future study and life.
