Mathematics review in senior three can be roughly divided into three different stages, and each stage has its specific tasks and requirements. The first round of systematic consolidation, the second round of special cleaning, and the third round of comprehensive simulation ◎ The first round of systematic consolidation takes a lot of time for math review in senior three, and it is also the most laborious for teachers and students. The problem to be solved in this round of review is: 1. We should be familiar with every definition, theorem and formula in the textbook and understand its essence, change and application. 2. For the typical problems of teaching materials, we should not only master the solution, but also think about its deformation and expansion and pay attention to its application. 3. The formation of knowledge network, the practice of solving small conclusions, the prevention of some problem-solving loopholes and the summary of problem-solving thinking methods. At present, the systematic review is to stay away from textbooks, embrace a round of materials and have a "sea of questions" with a lot of exercise. I don't agree whether this way can achieve efficient learning. This is because most of the information is extensive and generally difficult. Moreover, some knowledge points deviate from the specific requirements of the college entrance examination and have been improved and deepened too much. In this way, for students with weak foundation, its harm is self-evident. Therefore, the author's suggestions are as follows: on the one hand, the materials should be reasonably selected according to the reality of the college entrance examination and the students' own foundation; On the other hand, the systematic review should firmly grasp the five textbooks of senior high school mathematics, take the textbooks as the blueprint, browse, scan, imitate, copy, think and learn from time to time, and adopt the learning mode of teaching materials and auxiliary materials, which will certainly achieve better learning results. Since the resumption of the college entrance examination, the college entrance examination has experienced 30 years of ups and downs, and the theory, mode, form and law of the examination have gradually formed. For the review of college entrance examination mathematics, on the basis of a round of systematic study, the use of thematic review can improve the pertinence and effectiveness of mathematics preparation. Here, I'd like to introduce a way of topic division "3-6 principle". 3 is the multiple-choice questions, fill-in-the-blank questions and problem-solving questions in the college entrance examination, and 6 is based on the six directions of problem-solving. This division method is very compatible with the advantages of division by topic and division by test center. In view of this method, we will have a special topic below. At this stage, candidates should combine topics to exercise their comprehensive ability and test-taking skills, regardless of the sequence of knowledge structure, and cooperate with the study of topics to improve their ability to solve mathematical problems by using "matching method, undetermined coefficient method, combination of numbers and shapes, classified discussion and substitution method". At the same time, according to the characteristics of multiple-choice questions and fill-in-the-blank questions, they should learn some special problem-solving skills and methods to improve their ability to control time in the college entrance examination. ◎ The third round of comprehensive simulation On the basis of the first two rounds of review, it is necessary and effective to do a certain amount of simulated college entrance examination questions in order to enhance the pertinence and test-taking function of mathematics preparation. The problem to be solved at this stage is: 1. Strengthen the comprehensiveness and intersection of knowledge and consolidate the selectivity and flexibility of methods. 2. Check the knowledge omissions and mistakes in review, and explore the law of solving problems. 3. Test the generation process of knowledge network. 4. Understand the tools of mathematical thinking method in solving some real college entrance examination questions and novel simulation questions. You know, math study in senior three is a hard job, just like climbing a mountain. It needs direction, endurance and perseverance, and it is an exercise of human will. You know, a good memory is not as good as a bad written memory. Only by doing all-round information interaction with hands, eyes, mouth, ears and brain can we get the best learning effect. What we have always advocated is: learn by doing, think from learning and realize from thinking. Grasping five books in high school mathematics textbooks, flipping through them, memorizing the basic knowledge and methods, learning for understanding, gradually forming their own habits and methods of learning mathematics, reading, doing and thinking about a mathematical problem, quickly obtaining ideas and ideas for solving a mathematical problem, and being good at capturing the sense, inspiration and epiphany of solving problems. "What is it, why, and what else?"
