In the eyes of many primary school students, mathematics is a boring course. Compared with other subjects, mathematics is more logical and abstract, which causes many primary school students to have a headache when it comes to mathematics. Students are tired of math and don't like it. Of course, there are reasons for the characteristics of mathematics itself, but there are also reasons for classroom teaching [1]. A good math class is to let students remember those theorems and concepts, and then teach them to do exercises. Therefore, many math teachers only carefully prepare the new contents to be learned in each class when preparing lessons, but pay little attention to how to teach these new contents to students quickly and accurately. This has led many math teachers to follow the book and control the classroom by themselves, making the students in the classroom sleepy. It seems that the classroom has nothing to do with yourself. After a class, the teacher is full of sweat and satisfied, because the teacher feels that he has taught all the contents to the students, and even some key contents will be repeated several times. The teacher thinks that with such efforts, students' love for mathematics will surely be gained. But what about the facts? Pupils are used to the daily classroom mode and listen to the math teacher's nagging every day. The classroom atmosphere is like a mirror-a calm lake without any ripples. Pupils are not interested in learning at all, and they are bored and have a headache with mathematics.
