? With the deepening of teaching, many problems have been found.

? Mathematics is a very rigorous subject. In teaching, our teachers often pay too much attention to teaching logic and knowledge, which leads to depressed classroom atmosphere, boring students and low teaching effect. However, it is very difficult to have a good math class and make students listen interesting and learn easily. It is very important for teachers to guide at the beginning of class. If the beginning of the class is well introduced, it can highly stimulate students' knowledge and interest in learning, achieve twice the result with half the effort, and make the whole class very active.

Our mathematics comes from life and is used in colorful life. Maybe different teachers introduce mathematics in different ways, such as being good at questioning, being fond of induction, and being used to going straight to the point ... It can be said that "different people have different opinions, but learning mathematics will eventually return to life to solve some practical problems in life, so the closer we are to our real life in teaching, the easier it will be for students to accept and understand, and the better our teaching effect will of course be. Solving practical problems is no longer led by teachers, students follow teachers, but pay attention to students' words and regard themselves as one of the students. In this way, we can adjust the process of problem-solving teaching at any time according to students' autonomous learning, design and organize follow-up teaching activities, effectively promote the reform and innovation of mathematics problem-solving teaching, improve the quality of primary school students' problem-solving, and give full play to its theoretical value and application value.
