Prepare a piece of paper or use a mind mapping tool on an electronic device. Mind mapping can be based on a central theme, showing related concepts and ideas through branches and associations. In this example, the central theme can be written in unit 12 of the first volume of fourth grade mathematics.
Draw some key words or concepts related to Unit 1 and Unit 2 around the central theme, such as addition, subtraction, multiplication and division. These keywords should be placed around the central theme and connected with the central theme by a straight line. These keywords can be supplemented and expanded according to students' own understanding.
Branches extend from each keyword, indicating related sub-concepts or specific knowledge points. For example, there are branches extending from keyword addition, which can include carry addition and non-carry addition. Similarly, the corresponding branches are extended from other keywords to cover all the main concepts in Unit 1 and Unit 2.
On each branch, you can further draw sub-branches to represent more specific knowledge points or questions. For example, in the branch of keyword subtraction, sub-branches can be drawn to represent abdication subtraction, non-abdication subtraction and so on. In addition to the basic four operations, mind map can also add other related knowledge points and skills, such as equality, size comparison, number axis and so on. These can be shown as related but independent concepts of four operations.
The drawing of mind map is not only a linear process, but also can be adjusted and modified as needed. You can use colors, symbols and arrows to distinguish different types of concepts and mark related explanations or explanations.
Application of mind mapping
Mind mapping is not only applicable to mathematics, but also to the study and summary of other disciplines. Students can try to organize the knowledge of Chinese, English, science and other subjects with mind maps to help them better understand and remember what they have learned.
Mind mapping can also play a role in work and life. It can help to sort out ideas, organize information and improve work and study efficiency. By drawing a mind map, we can clearly see the relationship between concepts and better understand and apply what we have learned.
Drawing the mind map of the first and second units of mathematics in the first volume of the fourth grade can help students sort out and consolidate their knowledge, clarify their thinking and improve their learning effect. This is a simple and effective learning tool. By connecting knowledge points with keywords, students can build a knowledge framework and improve their ability to understand and master mathematics.
