1. Prepare a blank drawing paper and a colored pencil.

2. In the center of the drawing paper, draw a big square to represent the theme of "area".

4. According to this theme, expand the branches of thinking and fill in the contents.

Characteristics of mind mapping

Mind mapping is an effective tool because of its rigorous logic and deep memory, which can help us sort out and understand information and improve the memory effect. Through the guidance of logic, we can sort out scattered information, form a logical and orderly picture, and deepen our understanding of information.

At the same time, the mind map is also organized, which can be expanded in chronological order according to the theme, helping us to form a clear branch and knowledge system. Through mind mapping, we can organize a lot of information and form a memory framework, which is easier to understand and remember.

Mind mapping is expressed in the form of branches, each branch revolves around the central theme, and the expansion and divergence of branches echo each other. This divergent way of thinking allows us to look at problems from a broader perspective and avoid the shackles of fixed thinking. Through divergent thinking, we can think about the problem from multiple angles and find a more comprehensive solution.
