1, be familiar with the syllabus and master the teaching objectives.

The syllabus is the basis of teaching and the guiding document for teachers to compile teaching materials. To learn textbooks, we must first learn the junior high school mathematics syllabus, be familiar with the teaching objectives and requirements of the syllabus for the textbooks we have learned, and find out the teaching principles that should be followed, so that when compiling textbooks, we can put forward clear and appropriate requirements in terms of knowledge, skills, training ability and ideological education. Only in this way can we accurately grasp the teaching objectives, avoid blindly improving the teaching objectives, increase the depth and breadth of teaching materials, or lower the teaching requirements at will.

2, an overview of teaching materials, clear chapter status.

Textbooks are one of the main basis for teachers to prepare lessons. Teachers should try to browse the whole textbook to grasp the intention of compiling it; Master the content arrangement and purpose of the exercises, and make clear the position and role of each chapter in the whole textbook, as well as the relationship between them. In-depth study of teaching materials can also know the basic knowledge and context; Master the scientific, systematic and ideological nature of teaching materials; Distinguish the key chapters of the textbook, the key points, difficulties and emphases of each chapter; Dig deep into the ideological content of teaching materials and the potential factors conducive to students' intellectual development, and achieve the unity of ideological content, scientificity, systematicness and adaptability, so as to cultivate students' ability and develop students' intelligence. This is an important guarantee to achieve good teaching results.

3. Grasp the key points and determine the teaching center.

For the analysis of the teaching materials in specific chapters, we should combine the requirements of the syllabus, make careful analysis and in-depth research, and grasp the knowledge points, so as to determine the teaching center of this chapter. When determining the key points, we should also conduct in-depth analysis from the whole to the part and from the surface to the inner layer.

4. Find the difficulties and make breakthrough measures.

Difficulty generally refers to the part of knowledge that is difficult for middle school students to understand and accept, and it is a "roadblock" in learning. Therefore, when learning textbooks, we should analyze the textbooks according to students' knowledge level and ability, find out the teaching difficulties, and then formulate practical measures to break through the difficulties. The general principle of solving difficulties should follow the law of cognition, so that students can rise from perceptual knowledge to rational knowledge, and it is easier to break through difficulties and take corresponding measures to solve them according to the reasons of difficulties.

Through the above analysis, we realize that studying textbooks seriously is an important part of improving teaching quality and classroom teaching efficiency. There is no end to learning textbooks. Only by continuous progress and absorption can we improve day by day.
