How to review before the exam in mathematics?
First of all, we should take the mastery of basic concepts as the breakthrough of skills. In fact, the so-called problem-solving skills in mathematics test questions are not inscrutable things, they come from the most basic knowledge and concepts, and mastering them to a certain extent is an epiphany. Look for differences-because you have done many similar exercises, it is very dangerous to make mistakes in judging similar questions. Secondly, you should master the commonly used formulas and understand their ins and outs. This is very helpful for memorizing commonly used mathematical formulas. In addition, it is necessary to further understand the derivation process and explore some possible changes in the derivation process. This is better than doing a lot of exercises, and it can make you better master the application of formulas, which often has unexpected effects. Thirdly, we should grasp the trend of the senior high school entrance examination and practice the problem-solving norms diligently. Many students think that as long as they have answered the questions, they can get full marks. In fact, due to the deepening of the new curriculum reform, the senior high school entrance examination pays more and more attention to the standardization and integrity of the problem-solving process. As long as there is a process to solve the problem, the process is much more important than the final answer. Therefore, it is necessary to standardize the writing process and avoid the situation of "meeting but not being correct" and "being correct but not complete". Finally, we should grasp the mathematical thought and summarize the problem-solving methods. The mathematical thinking methods that often appear in the senior high school entrance examination are classified discussion method, area method, special value method, number-shape combination method and so on. We use the thought of transformation, equation, function and transformation to solve some comprehensive problems, memorize a corresponding typical test question in each method, and purposefully decompose the more comprehensive problems into several simple small questions, so as to draw inferences from others, simplify the complex and make a breakthrough step by step; In the cooperative study with classmates, we should combine relatively simple questions into more valuable comprehensive questions. The biggest feature of the senior high school entrance examination is shallow, wide, new and lively. Therefore, we should avoid complicated, difficult, biased and strange problems in review, otherwise it will waste time on the one hand and increase psychological burden on the other. It is suggested to study in different classes, and the math class in the senior high school entrance examination in Beijing New Oriental Youneng Middle School has been improved very well.
