1, the form and requirements of the first round of review: In recent years, a large proportion of questions in junior high school mathematics entrance examination have been arranged to examine "double basics". The whole volume covers a wide range of basic knowledge and has a low starting point. Many problems originate from textbooks, in which prototypes can be found, some of which are processed, combined, extended and expanded. In reviewing, we should stick to textbooks, lay a solid foundation and pay attention to the innovation in new textbooks. Systematically sort out the textbook knowledge, form a knowledge network, and at the same time carry out variant training on typical problems, so as to achieve the purpose of drawing inferences from others and improving the adaptability. In this stage of teaching, we have carried out special integration according to the spiraling characteristics of new textbooks. According to the number and formula, equation and inequality (group), function, statistics and probability, graphic understanding, triangle, quadrilateral, solving right triangle and circle, a systematic review is carried out. This stage is the basis and focus of the general review, and we should pay attention to both double-base training and circle training.
