First, improve the interest in review. Usually teaching new lessons, fresh and interesting; When reviewing, you should repeat what you have learned, and some students will feel monotonous. In view of this situation, on the one hand, we should improve students' understanding of review ideologically and take the initiative to review; On the other hand, we should improve the enthusiasm of review with "innovation". It is not only to let students review their knowledge, but more importantly, to let students master, consolidate and make up for the problems that the new teaching can't solve. Students should be given more space to feel another kind of scenery different from the new teaching in the review class, and let them feel the charm of the review class. Second, pay attention to synthesis and mastery. The content of mathematics review can be divided into two parts: basic knowledge and problem-solving skills. We should pay attention to the comparison and application of basic concepts, basic formulas and basic laws, and strive to integrate the basic knowledge we have learned from part to whole, from micro to macro, and from concrete to abstract, so as to consciously cultivate students' analytical understanding ability, comprehensive generalization ability and abstract thinking ability. For reviewing definitions, theorems and formulas, we should find out the ins and outs, communicate with each other, master the derivation process and pay attention to the expression form. Induce memory methods, make clear the main idea, make the knowledge points of each chapter interrelated, form a complete knowledge system, and achieve the purpose of connecting points into lines, lines into surfaces, and surfaces into a whole. Attention: 1, grasp the key points and highlight the key points. Mathematical thoughts and methods are the essence of mathematics, and they are the link of all kinds of knowledge in mathematics. It is not easy to understand the key content in the textbook. Mathematical thinking methods enable students to master analytical methods, guide students to think from different angles, and then break through important and difficult points. 2. Comprehensive review, understanding and mastery. The so-called "synthesis" refers to the refining and processing of mathematical knowledge learned in different disciplines, different units, different grades and different times, from the surface to the inside, from the shallow to the deep, thus establishing vertical and horizontal links between knowledge. It is easy to remember and apply. After mastering the basic knowledge, we should also pay attention to discovering and excavating the problems that are not in the book and not mentioned by the teacher according to the knowledge we have learned. For example, understanding the various connotations of a concept, thinking about a problem from different angles, summarizing the law of solving problems with * * *, and discovering the thinking method of solving problems, so as to explore the methods of multiple solutions to a problem, changing the problem, and using multiple solutions to the problem.
