First of all, we should strengthen the teaching of basic knowledge and the training of basic skills. The knowledge and skills mastered by students should not only be accurate and well consolidated, but also understand the vertical and horizontal relations between knowledge and grasp the relationship between form and practice. If there is such a defect in basic knowledge, when thinking diverges in all directions, it will always be blocked and stuck everywhere.

Secondly, we should help students master some thinking methods and mathematical methods to solve problems, such as correspondence, reduction, hypothesis, transformation, equivalent replacement and so on. , providing them with various methods to solve specific problems.

(3) Pay attention to language and cultivate students' divergent thinking.

Under the influence of traditional educational ideas, many students can easily answer the questions they see, but they are puzzled as long as they encounter some new problems or some original problems change slightly, which shows that their thinking lacks certain flexibility. Therefore, teachers can try to improve students' flexibility in language when teaching.
