1, addition and subtraction: I began to learn the basic knowledge of addition and subtraction in grade one, such as the composition of numbers, addition and subtraction operations and so on. With the growth of grade, students will learn more complicated addition and subtraction operations, such as addition and subtraction of multiple digits, addition and subtraction of decimals and fractions. The connection of these knowledge points helps students to master the operation rules and methods of addition and subtraction step by step.
2. Multiplication and division: Multiplication and division is one of the important contents of primary school mathematics. Grade two students began to learn the basic knowledge of multiplication and division, such as multiplication formula and multiplication and division operation. With the growth of grade, students will learn more complex multiplication and division operations, such as multiplication and division of multiple digits, multiplication and division of decimals and fractions.
3. Graphics and geometry: Graphics and geometry are one of the important contents of primary school mathematics. In the third grade, I began to learn the knowledge of graphics and the basic knowledge of geometry, such as rectangle, square and circle. With the growth of grade, students will learn more complex graphics and geometry knowledge, such as cuboids, cylinders, cones and so on.
4. Statistics and probability: Statistics and probability are one of the important contents of primary school mathematics. In the fourth grade, I began to learn the basic knowledge of statistics, how to collect, sort out, analyze and describe data. With the growth of grade, students will learn more complicated statistical knowledge, such as how to study random phenomena and predict the possibility of events.
The relationship between primary school mathematics knowledge points refers to the relationship and influence of mathematical concepts, skills and methods between different grades and different knowledge points. These connections can help primary school students better understand and master mathematical knowledge and form a complete mathematical system.
In short, the relationship between primary school mathematics knowledge points is a complete system, and each knowledge point is interrelated with other knowledge points. Pupils can gradually build a complete mathematical system and improve their mathematical literacy and ability by constantly learning and mastering new knowledge points.
Methods of learning mathematics
1. Understand the basic concepts and formulas: from the shallow to the deep, understanding the basic concepts and formulas of mathematics is the basis of learning mathematics.
2. Exercise topic: Do more examples and problem sets, understand the ideas and methods of solving problems, and master basic problem-solving skills.
3. Establish contact: apply mathematics to practical problems, such as physics, chemistry and engineering. , enhance the understanding and application ability of mathematics.
4. Communicate and discuss with others: use community or network resources to communicate and discuss math problems with others, learn from each other and deepen understanding.
5. Use teaching materials, reference materials and software: deepen the understanding of mathematics knowledge and improve learning efficiency.
6. Keep practicing and reviewing: improve math skills and enhance the ability to understand and apply math.
