In the first stage, it is the longest and most critical period for the senior high school entrance examination to highlight the foundation and lay a good job in the "eight-part battle" of the general review. We should focus on training from basic knowledge, basic methods and basic skills. Only by laying a good foundation can we skillfully use knowledge and increase "stamina" for the review in the latter two stages. In recent years, the proportion of basic questions in the senior high school entrance examination in various provinces and cities is very prominent. This is an inevitable requirement for deepening education reform and teaching reform. Therefore, the quality of basic review directly affects the results of the senior high school entrance examination. Pay attention to basic knowledge points such as definition, theorem and nature in review. At the same time, we should also pay attention to various basic methods and mathematical ideas to solve mathematical problems. The basic methods are: collocation method, method of substitution method, equal area method, undetermined coefficient method, elimination method and so on. The basic thinking methods are: combination of numbers and shapes, transformation, equation inequality, function, whole and classified discussion. In the review, pay attention to the essence of each mathematical method and the types of questions it applies, including the steps of solving problems. Mathematical thinking method is the soul of mathematics, which reveals the essence of mathematical concepts, principles and laws, and is a bridge to communicate basic mathematical knowledge and various abilities. Mastering methods and understanding ideas can further enhance students' ability to analyze and solve problems.

In the second stage, strengthen the ability and lay a good "tough battle". The second stage of review, also called longitudinal review, mainly focuses on the formation of problem-solving ideas, laws and skills, and interweaves with the knowledge points in the first stage to form a knowledge network. The goal is to let students see that there are solutions to problems and skills.
