1, determine the central theme:
The theme of this mind map is "Understanding the Times".
2. List the minor themes:
The secondary theme should be the refinement or expansion of the central theme, such as "how many times is one number another", "how to solve how many times is one number another" and "the meaning of multiple". These topics should closely follow the central theme and guide students to think and explore deeply.
3. Expand the node:
According to the secondary theme, more nodes can be further expanded. For example, the node "the meaning of multiplication" can be expanded into child nodes such as "how many other numbers there are in one number, that is, how many times one number is another" and "the practical use of multiplication".
The Actual Usage sub-node can be expanded into such sub-nodes as Salary Multiply and Shopping Discount. Each node should be a sub-topic of the secondary theme or related mathematical concepts, and can guide students to deeply understand and master each theme.
4. Add related lines:
Add an association line between each node to indicate the connection and relationship between them. For example, two nodes "Salary Multiply" and "Shopping Discount" can be connected by an association line, indicating that they are all children of the node "Meaning of Multiply".
At the same time, the connection and difference between them can be marked on each connecting line, so as to better guide students to master the internal connection between mathematical concepts.
Step 5 perfect the details:
Finally, the details of mind mapping can be further improved. For example, add more explanations and descriptions on each node, such as definitions, attributes, formulas, etc. Or add some examples and examples to the mind map to better understand and remember mathematical concepts and themes.
In addition, different colors or symbols can be used to mark important or difficult contents, so as to better help students master key knowledge points.
