1. Theme: First, write down the theme in the center of the paper and enclose it with a big circle or box. Branch: Next, draw several branch lines from the big circle or box around the theme, and each branch line represents an aspect or sub-theme of the theme.
2. Keywords: On each branch line, write down the relevant keywords, which can be concepts, vocabulary, definitions or any information that needs to be memorized. Sub-branches: If a branch needs further decomposition, you can draw some sub-branches from this branch.
3. Relevance: Show the relevance between different topics by drawing some arcs or two-way arrows. Key points: For some very important knowledge points, you can emphasize them with pens or padding of different colors.
Learning content of four units of mathematics in the first volume of the third grade
1, the fourth unit of mathematics in the first volume of the third grade mainly involves the knowledge of multiplication and division. The theme of this unit is "multiplication", starting with the most basic multiplication operation, and gradually introducing more complex multiplication concepts.
2. First, students will learn how to perform basic multiplication. This includes multiplication of integers, decimals and fractions. Through examples and exercises, students will master the basic principle and operation method of multiplication.
Next, the students will learn the multiplication table, which is the basis of fast multiplication. The multiplication table contains the multiplication results from 1 to 10. Students need to remember these results in order to get answers quickly and accurately in future operations.
4. Then, students will learn how to do some simple multiplication estimation. Estimation is a method to get general answers quickly, which is very useful for solving practical problems. Students will learn how to estimate the range of results and how to adjust their answers to make them more accurate.
Finally, students will learn some more complicated multiplication concepts, such as factor, multiple and common multiple. These concepts are very important for understanding more advanced mathematical concepts and solving more complicated mathematical problems.
