Review some suggestions based on textbooks: 1, and attach importance to the consolidation and improvement of basic knowledge and methods. Although there have been many new questions in the senior high school entrance examination mathematics in recent years, the traditional basic questions still account for a large proportion of the scores. In the first stage of preparing for the senior high school entrance examination, we should take textbooks as the blueprint. In particular, the review of basic questions should be achieved through the review of typical examples and exercises. 2, pay attention to the use of knowledge and skills to analyze and solve problems. Actively participate in observation and experimental activities, and complete the conjecture and proof of knowledge through comparison, analysis, induction, analogy and abstraction. This can not only deepen the understanding of knowledge, but also learn creative strategies and methods. 3. Strengthen simulation exercises, and strengthen the mastery of knowledge and the accumulation of training in answering questions in terms of speed, rhythm and experience. , and training test ability. Some students usually get good grades, but they don't do well in the exam. This problem can be solved by strengthening training. Use the test paper with the same structure as the senior high school entrance examination paper for simulation training. When reviewing, we should pay attention to standardized training, answer questions in strict accordance with the requirements of the senior high school entrance examination, answer questions in a standard format, and correct bad habits in the process of answering questions. 4. Correctly treat the content deleted from the new outline. On the one hand, the revised outline omits the use of chord tangent angle theorem, intersecting chord theorem and line cutting theorem in relevant proofs; Accordingly, the plane geometry test questions turn to examine students' understanding and reasonable reasoning ability of geometric facts, which obviously reduces the difficulty of geometry test questions. On the other hand, it weakens the special investigation of quadratic equation knowledge in algebra, and only needs to solve simple quadratic equation with numerical coefficients. However, knowledge points can be reduced, thinking methods have not been reduced, and students should treat them correctly.
