1. First of all, the central theme is "Mathematics". Then starting from the central theme, we can draw two main branches, one is "number understanding" and the other is "calculation".
2. Under the branch of "Understanding Numbers", subtopics can be added, such as "Meaning of Numbers", "Reading Numbers", "Writing Numbers" and "Comparing Numbers". Under each sub-topic, you can further add more detailed content. For example, under the digital reading method, you can add the reading method of 1- 10 and the reading method of 10 or above.
3. Under the "Calculation" branch, you can add sub-topics, such as "addition", "subtraction" and "mixed operation of addition and subtraction". Under each sub-topic, more details can be added. For example, under "addition", "1- 10 addition" and "two-digit addition" can be added.
4. In addition, you can add some additional branches, such as "measurement" and "clock". Under the "Measurement" branch, you can add subtopics, such as "Length Measurement" and "Weight Measurement". Under the "Clock" branch, you can add sub-topics, such as "Understanding Time" and "Reading and Writing Time".
The drawing steps of the mind map center map are as follows:
1, in the middle of a piece of A4 paper, draw a rectangle with appropriate size. The size of this rectangle depends on the size of your mind map, which accounts for about one ninth of the paper size. Write down your theme or central idea in this rectangle, and make sure that the theme or central idea stands out so that people who see it can see it at a glance.
2. Around the center map, you can add some graphics or patterns, which can further emphasize your theme or central idea and make your mind map look more attractive. Finally, add colors to your central map. You can choose multiple colors, because this will increase the attractiveness and readability of your mind map.
