According to the teaching content to be reviewed, teachers create situations that can arouse students' interest in learning and let students actively participate in the review class. Whether students' interest in learning is stimulated directly affects the learning effect of review class. Therefore, teachers should attach importance to the creation of situations, integrate the reviewed mathematical knowledge into problem situations, and stimulate students' urgent desire to review and explore. At this time, they should seize the opportunity to ask for review and achieve natural results.

Second, stimulate desire and recall knowledge.

Collect all the knowledge related to the subject by recalling and browsing the teaching materials. Because the subject itself contains different knowledge points, some knowledge will reappear in students' minds soon, while some knowledge may be forgotten. It is an important foundation for students to collect knowledge related to the subject and understand the meaning of each knowledge point through recollection and reproduction. When students can't fully recall, they can combine the teaching materials to search. When recalling and searching, we should make records in time, and then sort out the knowledge structure network according to the recorded knowledge points and problem-solving methods. Therefore, it is an important basis for students to collect knowledge related to the subject and understand the meaning of each knowledge point through the recall and reproduction of the teaching materials.
