Ask the students "four views and four degrees": to see if they have skillfully answered the common questions in the college entrance examination in recent years, whether they have accurately grasped the "degree" of the examination requirements-the three progressive levels of "understanding, understanding and mastering" in the examination instructions, and clearly defined "what to test" and "how to test"; Second, see if you keep up with the teacher's ideas, take notes properly in class, and grasp the "degree" of listening, remembering and practicing; Thirdly, it depends on whether the series of knowledge and the pertinence of practice are strong, whether the vague knowledge can be made clear, the missing parts can be made up, the messy methods can be sorted out, and the isolated knowledge can be linked to form a systematic and organized knowledge framework, thus controlling the "degree" of the difficulty of the test questions; Fourth, see whether the practice or test is suitable for the college entrance examination, which content should be slightly raised and which content should not be lowered, and the primary and secondary levels are appropriate. Emphasize the flexible application of basic knowledge and the mastery of common mathematical thinking methods, and pay attention to the "degree" of timely feedback. When the first round of college entrance examination review is coming to an end and the second round of review is about to begin, time is tight and the task is heavy, which often takes about 40 days. How to review in an orderly way? According to my recent study and many years' practice, I would like to talk about the following views for the reference of my peers.

First, build a knowledge network, design college entrance examination questions, pay attention to the integration of mathematical knowledge and the internal relationship of knowledge, and pay special attention to the design of questions at the intersection of knowledge networks. Knowledge points are still isolated in our ideology. The process of two rounds of review is a process of deepening the basic knowledge and methods of mathematics. It is necessary to know and understand the essential relationship of mathematical knowledge, so as to classify, summarize and synthesize it and form a systematic, orderly and clear knowledge structure system. In this way, when solving problems, we can extract relevant knowledge points according to the information provided by the topic, organically combine them, and explore the ideas and methods of solving problems.

1. Seven main pieces of knowledge

(1) function and derivative (and its application); (2) Inequality (solution, proof and application) will not be put forward separately, but often appears in the form of tools, such as finding the range and comparing the size. ); (3) Sequence (and its application); (4) trigonometric functions (images, properties and transformations); (5) Straight lines and planes and simple geometry (calculation of three angles and seven distances in space (the distance between points and planes and straight lines in different planes are common tests), area and volume); (6) Straight lines and conic curves; (7) Probability statistics (expectation, variance and normal distribution estimation in science).

2. Master four mathematical thinking methods.

The rational thinking method of mastering mathematical knowledge is clearly embodied in the four major mathematical thinking methods. The four mathematical thinking methods are: ① the thought of function and equation; (2) the idea of combining number with type; ③ The idea of classified discussion; (4) the idea of reduction or transformation permeates the problem to think and comment.

3. Pay attention to the guidance of learning the law-grasp the four three.

① We should fully understand three aspects in content: theory, method and thinking;

② Three words should be grasped in solving problems: number, shape and shape;

(3) Reading, examination and expression should realize the free conversion of three mathematics languages (written language, symbolic language and graphic language);

④ Three lines should be mastered in learning: knowledge (structure) is a bright line (to be clear); Method (ability) is a hidden line (to be understood and refined); Thinking (practice) is the main thread (thinking ability is the core of mathematical ability, creative thinking ability is the most powerful driving force for innovation, and it is the touchstone to test the development of a person's brain potential. )
