There are four chapters in the first volume of seventh grade mathematics published by People's Education Press, which is the basic knowledge of algebra and geometry in junior high school mathematics. It is very important to learn the mathematics knowledge of these four chapters well for the subsequent junior high school mathematics knowledge learning.
The first chapter is rational numbers, including five sections: 1. 1 positive and negative numbers, 1.2 rational numbers, 1.3 rational numbers addition and subtraction, 1.4 rational numbers multiplication and division, 1.5 rational numbers. The mind map in this chapter can be set like this.
The second chapter is algebra addition and subtraction, including two sections: 2. 1 algebra and 2.2 algebra addition and subtraction. The mind map in this chapter can be set like this.
The third chapter is the linear equation of one yuan, including four sections: 3. 1 from formula to equation, 3.2 solving the linear equation of one yuan (I)-merging similar terms and shift terms, 3.3 solving the linear equation of one yuan (II)-removing brackets and denominator, and 3.4 solving practical problems and linear equation of one yuan. The mind map in this chapter can be set like this.
The fourth chapter is a preliminary geometric figure, including three sections: 4. 1 geometric figure, 4.2 straight line, ray, line segment and 4.3 angle. The mind map in this chapter can be set like this.
The focus of this chapter is to guide children to transition from formula to equation, and to ask children to correctly understand the concepts of "equation" and "solution of equation" and understand the basic properties of equation, so as to use the basic properties of equation to solve equation;
It is mainly to master some basic concepts and understand the three main characteristics of linear equations (marked by the small icon "pink telescope"). The difficulty, or the key point, lies in the equation "finding the equivalence relation" (marked with the small icon "green eyes").
The research results of brain science show that using mind map to learn is one of the recognized efficient learning methods. Teacher Zhang Pengsheng, an expert in mind mapping research in China, has compiled more than 30 monographs and series on mind mapping, among which The Complete Works of Mind Mapping in Junior High School Mathematics, which is based on junior high school mathematics textbooks published by People's Education Press, is very helpful for junior high school students to learn mathematics well.
