First of all, we spend half our time guiding students to review the contents of textbooks, focusing on the key points, difficulties, test sites and doubts in reviewing textbooks. The method is a combination of teacher guidance and students' independent review. In the review, students pay attention to checking and filling gaps, and teachers pay attention to solving doubts and doubts. In the review, we should pay attention to the problems existing in students' comprehensive exercises, and check students' knowledge mastery and ability to use knowledge in time. And do timely feedback, fill in the gaps in time, and minimize the missing points. Then spend a quarter of the time reviewing in stages, and review the unit content related to the content item by item. For example: review of numbers, review of geometry knowledge and so on. Combine different review contents. Identify different review points and difficulties, sort them out, and strengthen the systematicness of review. This is conducive to the systematization of knowledge and the grasp of its internal relations, which is convenient for integration. Do combing-training-expanding, orderly development, and really improve the review effect. The last quarter of the time is spent on comprehensive review, various questions and so on. In each comprehensive review, the ability of middle school students presents a spiral state.

2. Guide students to review skillfully.

Concepts, formulas, calculations and so on in mathematics learning are very boring. As the saying goes, "Practice makes perfect." A good review method is an important way to improve the review efficiency. Use all effective means to fully mobilize students' initiative, creative knowledge and skills in review. Teachers should do four things in guiding review: the first is to set the tone. Give a review "guide sheet" to let students review according to the "outline" and master basic knowledge and skills. The second is to give the law. Give specific guidance on review methods. Be good at grasping key organizations to review. The third is the tree target. Discuss the difficult problems in the review and examine the authenticity. The fourth is to set the sample. Give a positive answer to the result of the debate, clarify the vague understanding and establish a correct view.

3. Guide students to explore skills and rules to improve their abilities.

Ability test is the main aspect of modern mathematics test, such as practical ability and innovative ability. Therefore, in the review process, students should be instructed to do some calculation exercises and innovative exercises regularly. Know that students master the key conditions of solving problems and the mathematical relationship in application problems, and summarize the laws and methods; Guide students to remove obstacles; For some seemingly complicated questions, guide students to cut branches and leaves, find out the core part, understand the meaning of the question faster and more accurately, and thus effectively complete the required answers. In this process, remind students not to memorize, broaden their horizons, cultivate their practical ability and explore skills and rules.
