First, determine the central theme.
At the center of the mind map, write down the theme or title of Unit 4. Such as the understanding of numbers or the operation of numbers. This theme will be the center of your whole mind map, and everything else will revolve around this theme.
Second, add the main branch.
According to the theme of Unit 4, take the main content in the textbook as a branch of mind map. For example, the theme is the understanding of numbers, and we can take the understanding of integers, fractions and decimals as the main branch. These branches will be the secondary titles of your mind map and an important summary of the whole unit.
Third, add details.
Under each main branch, list relevant knowledge points and important concepts. For example, under the understanding of integer, we can list what is integer, the classification of integer and other details. These contents are further explanations and explanations of various branches, and they are also an important part of your learning mathematics knowledge.
Drawing method of mind map:
1, flow chart method
Flowchart method is a drawing method which uses arrows and boxes to represent the process sequence. In the mathematical mind map, we can connect each knowledge point with arrows and boxes according to its position in the textbook to form a flow chart. This method can help us better understand the logical order of mathematical knowledge. For example, in the unit of digital cognition, we can connect the cognitive processes of integers, fractions and decimals with arrows and boxes in the order in which they appear to form a flow chart.
2. Concept map method
Concept map method is a drawing method which represents concepts through nodes and the relationship between concepts through connecting lines. In the mathematical mind map, we can regard each concept as a node and connect their relationships with lines. This method can help us better understand the concepts and relationships of mathematical knowledge. For example, in understanding the unit of numbers, we can take the concepts of integers, fractions and decimals as nodes and connect their relationships with lines to form a concept map.
3, table method
Tabular method is a drawing method that arranges mathematical knowledge points into tables. In the mathematical mind map, we can organize each knowledge point into a table, including the name, definition, examples, exercises and so on. This method can help us better sort out and understand the knowledge points of mathematics. For example, to understand the number unit, we can organize the knowledge points of integers, fractions and decimals into tables, including their definitions, examples and exercises.
