1, we should clearly understand the knowledge structure presented in the math textbook. As a primary school math teacher, you should have a clear understanding of all the math knowledge in primary schools for at least six years, and what level students in each grade should reach. (If you can understand junior high school mathematics knowledge, of course, it will be better. Only in this way can teachers look at their own teaching from a developmental perspective and lay a solid foundation for students' further study. Moreover, only with a deep understanding of the subject knowledge system taught can we put ourselves in the eyes of students, make self-study truly meet the actual needs of students and promote their effective development.

2, to widely read primary school mathematics education and teaching books. Reading is an important way to improve people's literacy. As primary school mathematics teachers under the new situation, we should collect and read more books and periodicals about primary school mathematics education and teaching. Such as Curriculum Theory, Primary Mathematics Teaching Theory, Primary Education Theory, Primary Mathematics Education and Primary Mathematics Teachers will be of great help. Maybe we will feel that some professional knowledge is too far away for us to understand or understand. In fact, if you read too much, you will naturally understand. Therefore, teachers should also actively explore the unknown knowledge.

3. Study some "teaching cases". Case is a kind of theory and practice, and it is a research method to cultivate researchers' ability of case reflection and teamwork. Universality is more important than particularity, and it is manifested through particularity. This case is both typical and specific. Through the analysis of some cases, teachers' teaching ability can be improved. In this regard, helping young teachers is particularly effective. Therefore, teachers should attach importance to teaching cases and study them.

4. Actively participate in training activities in various subjects. Pre-service education has given us an important foundation for education and teaching, but we should continue to learn, especially to participate in training and learning. Some training activities for training institutions or disciplines. Such as new curriculum training, school-based training, network training, teaching material training, etc. Our primary school math teachers should take an active part. Improve our professional level.
