When you are in class, you know all the knowledge points like the back of your hand. Only when you teach can you be comfortable. In this way, students will admire you, like your class and listen carefully in class. Therefore, after class, we should carefully study teaching materials and methods, analyze students' learning basis and individual differences, and make clear what is difficult for students to understand, what is difficult to remember, what is easy to be ignored and what is easy to be confused, so as to be aware of it. Often consult some extracurricular materials related to teaching, enrich the classroom content and stimulate students' interest in learning mathematics. In classroom teaching, it is necessary to allocate time correctly, make rational use of every teaching link of review, new lessons and consolidation, make appropriate details, combine work and rest, and combine teaching with practice to optimize the classroom teaching structure.
