1, basic operation: This part mainly talks about the basic concepts and applications of addition and subtraction. The main operation methods, such as addition and subtraction, can be listed in the main branch. For each operation method, its application and examples can be further expanded, such as 1+ 1=? Or 8-3=? Wait a minute.
2. Measurement and comparison: This part mainly includes the measurement and comparison of object length. You can list the basic concepts and methods of measurement in the main branch, such as measurement and comparison. Then we can further expand the examples and applications of each concept, such as how to measure the length of an object with a ruler or compare the lengths of two objects.
3. Simple geometry: This part mainly talks about the basic knowledge of geometric figures. You can list the main geometric figures on the main branch, such as circles, squares, triangles, etc. For each geometric figure, its characteristics and applications can be further expanded, such as the characteristics of circles, the definitions of squares and triangles, etc.
Drawing Skills of Mind Map in Unit 4 of Mathematics in Senior One;
1. Determine the central theme: You need to determine the central theme before starting to draw a mind map. This central theme should be the most important concept or knowledge point in this unit, such as basic operation, measurement comparison or simple geometry. Put the central theme at the center of the mind map, and then expand other related knowledge points around it.
2. Use colors and images: Using colors and images can make mind maps more vivid and interesting and attract students' attention. Different colors can be used to distinguish different knowledge points, such as red for addition and blue for subtraction. At the same time, images can be used to express abstract concepts, such as measuring with a ruler.
3. Use keywords and phrases: When drawing a mind map, use keywords and phrases to express the core content of each knowledge point. Keywords and phrases should be concise and clear, which can accurately summarize the meaning and content of each knowledge point. By using keywords and phrases, students can better remember and understand the content of each knowledge point.
