Mathematics is a highly logical and systematic subject, which requires students to think deeply and organize their knowledge effectively. Zailiu

In the mathematics study of the first volume of the grade, we will come into contact with many core concepts and key skills, such as concepts, algebraic expressions, formulas and so on.

Process, fractional operation, simple calculation, application problems, geometry, graphics, preliminary knowledge of location, etc.

The concept of 1. Numbers

The concept of number is basic knowledge, including integers and fractions, in the first volume of mathematics study in grade six. Integers include positive integers, 0 and negative integers.

Integers, and addition, subtraction, multiplication and division of positive and negative integers. Comparing the size is a way to judge the size of a number, which can be judged according to the size of the number.

Small to judge its absolute value.

2. Algebraic expressions and equations

Algebraic expressions and equations are important concepts in mathematics. Algebra is a formula composed of operation symbols and letters, while equation is a kind of.

A solution to the problem. By establishing the equation relationship between the unknown quantity and the known quantity in the problem, the unknown quantity can be solved by the numerical value of the known quantity.

The value of a number. Learning to use equations to solve practical problems is one of the important goals of sixth grade mathematics.

3. Fractional operation

Fraction addition, subtraction, multiplication and division is one of the important contents of sixth grade mathematics. Students will learn the concept of fractions, addition and subtraction of fractions,

Basic skills such as multiplication and division of scores also involve knowledge points such as the comparative size of scores. Fractional application problems are also being studied.

One of the difficulties in learning is to correctly use the addition, subtraction, multiplication and division of scores to solve problems by analyzing the quantitative relationship in the questions.

4. Simple calculation

Simple calculation is one of the important skills in sixth grade mathematics, which can help students solve problems quickly and accurately. Through simple use

This calculation method can avoid lengthy calculation process, reduce calculation error and improve calculation efficiency.

Students will learn basic simple calculation methods, such as associative law and distributive law, and some common simple calculation skills, such as

Extract common factors, simplify scores, etc.
