The unit review of mathematics is an important link that must be carried out to do a good job in the review exam, especially the general review, which faces outstanding problems such as less time, more content and higher requirements. How to review well in a short time?

Review knowledge, bring discussion, and form a knowledge network.

The teacher first arranges a unit for the students to review. Let the students learn the teaching materials independently according to the specified requirements (understanding those basic concepts, mastering those theorems, and sorting out the problem-solving ideas of various types of questions), summarize the knowledge and extract the main points of knowledge. Instruct students to list the main points of knowledge in the form of a list to deepen their memory. Finally, instruct students not to read books, recall the main contents of each section of this unit, and read books if they can't remember them, so that students can really understand and master the basic concepts and theorems of this unit. Then sit at the same table or discuss in groups in class, and connect the knowledge of this unit with a main line to form a knowledge network.

2.* * * Explore and implement concepts and knowledge.

Set some questions about the mathematical concepts and knowledge in this unit for students to talk about. What do you know about monomials? Will you merge similar projects? How to merge and so on.

3. Let the students review the difficulties and problems in this chapter.

Teachers should make appropriate contacts to make students understand. What do you think is the focus of this chapter? Where is the difficulty? What problems should we pay attention to? Write it out first through personal thinking and make up for other students'.

4. Teachers and students discuss and summarize the problem-solving ideas, methods and skills of various types of questions in this unit; Pay attention to the learning methods and mathematical ideas that should be mastered in this chapter, so that students can experience the functions of various methods.

5. Teachers and students should jointly check and evaluate the review effect. According to the teaching requirements, students' homework in this chapter and the exercises that are easy to make mistakes at ordinary times are configured, and students at different levels are required to answer questions according to their characteristics. When setting questions, we should pay attention to proper improvement and contact with learning methods, and strengthen contact with real life as much as possible. Improve the types of questions and try to make students "jump".
