Wang Jinqiao, No.2 Middle School, Tongjiang City, Heilongjiang Province: The first stage: comprehensively review the basic knowledge and pay attention to the foundation. The purpose of strengthening the review of basic skills training at this stage is to enable students to fully grasp the basic knowledge of junior high school mathematics, improve their basic skills, be comprehensive, solid and systematic, and form a knowledge network. 1. Pay attention to textbooks and review them systematically. Let the students review their textbooks. You must delve into the textbook and never leave it behind. The examples, exercises and homework in the textbook should be understood and done accurately by students. We should concentrate on doing the examples and exercises of key contents well one by one, and pay attention to the induction and arrangement of problem-solving methods. Teachers' teaching at this stage can be reviewed according to the knowledge block, and the algebra part can be divided into five units: real number and algebra; Equation; Inequality; Function; Preliminary statistics, etc. ; The geometry part is divided into five units: the basic concept of geometry, intersecting lines and parallel lines; Triangle; Quadrilateral; Solve right triangle; Circle and so on. 2. Lay a good foundation and learn to think. In the review teaching of ninth grade mathematics, we must lay a solid foundation, and through systematic review, every student can meet the requirements of "understanding" and "mastering" junior high school mathematics knowledge; Apply basic knowledge skillfully, correctly and quickly. 3. Pay attention to the understanding of basic knowledge and the guidance of basic methods. Students are required to master the internal relationship between knowledge points, clarify the knowledge structure, form an overall understanding and comprehensively apply it. In addition to paying attention to the basic knowledge, the mathematics proposition of the senior high school entrance examination also attaches great importance to the examination of mathematical methods. When reviewing, we should deal with the connotation of each method, and we should master the types of questions it adapts to, including the steps of solving problems. The second stage: comprehensive application of knowledge, focusing on ability. In the second stage of reviewing the senior high school entrance examination, we should focus on building the knowledge structure and network of junior high school mathematics, grasp the mathematics content as a whole and improve our ability. 1. The ability of students to learn to solve problems by using mathematical knowledge comprehensively is one of the important purposes of learning mathematics. The purpose of review at this stage is to let students relate the knowledge of each chapter and apply it comprehensively, so as to draw inferences from others. The examples and exercises at this stage should be difficult, but the harder the better, so that students can accept them. This can not only stimulate students' desire to solve difficult problems, but also see their own strength from solving difficult problems and enhance their confidence in progress. The classified query of periodical articles is in the periodical library. If the first stage is the basis of the general review, and it is the key point, focusing on double-base training, then the second stage is the extension and improvement of the first stage review, focusing on cultivating students' mathematical ability. Teachers should carefully design the teaching methods of review class to improve the review efficiency. 2. The concept of cultivating students' ability should run through the whole review. The examination of ability in the mathematics test questions of senior high school entrance examination is characterized by the examination of calculation ability, spatial imagination ability, logical thinking ability and the ability to analyze and solve pure mathematical problems. These abilities require strengthening students' reading comprehension ability, exploration and innovation ability and mathematics application ability, as well as their thinking ability based on these abilities. Especially when mathematics is regarded as an inseparable part of culture and the cultivation of "people", the examination of students' non-intellectual factors such as emotion, perseverance and values will inevitably make the examination of mathematics questions in the senior high school entrance examination enter a new stage. The third stage: fully simulated senior high school entrance examination training, focusing on special events. 1, the ninth grade review should focus on cultivating students' mathematical ability in all aspects, mainly from the following aspects. (1) Change the expression form of the proposition and cultivate the profundity of students' thinking. Strengthening this kind of training can help students form a deep understanding of the nature of knowledge, thus cultivating their ability to examine questions. (2) Seek different methods of solving problems and ways of thinking, and cultivate the broadness of students' thinking. Different ways of thinking lead to different methods of solving problems, so training is conducive to breaking the mindset, developing students' ideas and optimizing problem-solving methods, thus cultivating students' divergent thinking ability. (3) Transform the position, shape and size of geometric figures, and cultivate the flexibility and agility of students' thinking. Guiding students to change the example exercises in class at different levels not only strengthens the connection between knowledge, but also stimulates students' interest in learning, thus consolidating knowledge and cultivating ability. (4) Change the conditions and conclusions of the topic and cultivate students' critical thinking. This kind of training can overcome students' habit of looking at problems statically and in isolation, promote students' re-understanding of mathematical thinking methods, and cultivate students' ability to study and explore problems. 2. Pay close attention to key contents and practice hot issues appropriately. 3. Basic knowledge of leak detection. After the first round of review of basic knowledge, students have a firmer grasp of mathematics knowledge and thinking methods in junior high school for three years. However, in the process of reviewing and training, students will always find that they have not mastered some knowledge and have no ideas to solve problems. Therefore, we should seize the time to understand the ideas and methods to solve these problems, and then find similar problems for students to do, and never give up easily before students really understand and can do them. 4. Pre-war training, mock senior high school entrance examination. After reviewing the basic knowledge and key contents, we should do some simulation questions to check the review effect, so that students can adjust their mentality and cheer up. Teachers should carefully analyze the test papers, find out the problems existing in students and solve them, and strengthen the practice in this respect. Mathematical knowledge lies in the accumulation of dribs and drabs. Students should learn to be calm when they encounter problems that they can't do in the exam, recall all kinds of methods they have learned, start with conditions, dig out hidden known conditions, or start with conclusions, find ways to solve problems, and strive for excellent results in the senior high school entrance examination.
