1, determine the central theme.
According to the main contents of the first and second units of mathematics, determine the central theme. For example, the understanding of numbers and addition and subtraction can be the central theme. Then around these two central themes, the follow-up branches and contents are launched.
2. Branches and directories
According to the specific contents of the first and second units of mathematics, fill in the contents in branches. For example, under the theme of digital cognition, it can include integer cognition, fractional cognition and decimal cognition. Under the theme of addition and subtraction, it can include the basic concept of addition and subtraction and its application.
3. Mind mapping
After determining the central theme and branch content, I began to draw a mind map. You can draw by hand or by software. You can draw by hand with paper and colored pens. The thesis is divided into several parts, representing different themes and branches. Draw different figures or patterns on paper with colored pens to show the relationship between various topics and branches. For example, you can use a tree diagram to represent the hierarchical relationship between topics.
The importance of third grade mathematics;
1. Basic knowledge: Junior three mathematics involves a lot of basic mathematical knowledge, including addition, subtraction, multiplication and division, the calculation of fractions and graphs. This knowledge is not only necessary for daily life, but also the basis for further study of mathematics and other scientific disciplines.
2. Thinking ability: Mathematics in the third grade is not only to let students master mathematical knowledge, but more importantly, to cultivate students' mathematical thinking ability and problem-solving ability. This includes logical thinking, abstract thinking and spatial thinking. These thinking abilities are of great help to future study and life.
3. Learning methods: Junior three students have just started to contact more complex mathematical concepts and topics, and need to gradually master more effective learning methods. For example, how to solve application problems, how to analyze problems, how to use formulas and so on. These learning methods can not only help them master mathematics knowledge better, but also lay a foundation for their future study and work.
