1. The teaching goal is unclear. With the promulgation of the new curriculum standard, the teaching goal has been promoted to the core literacy goal on the basis of the three-dimensional goal, but most teachers still design their teaching on the basis of "double basics" and basic knowledge and skills, ignoring the cultivation of basic ideas and basic activity experience, not to mention the achievement of the core literacy goal.

2. The teaching content is mechanically copied.

The new curriculum standard puts forward that in order to improve mathematics teaching in primary schools, we must create real situations and guide students to think independently and explore independently. But in fact, in classroom teaching, it is still mechanically copied, which affects the quality of teaching.
