Mathematical culture is an important part of human culture. It is a cultural system with mathematical science system as the core and mathematical thought, concept, spirit, knowledge, method, technology, theory and mathematical development history as the main contents. With the development of mathematics, we constantly enrich our own content. This paper expounds the significance of infiltrating mathematical culture into middle school mathematics teaching, analyzes some problems existing in middle school mathematics teaching at present and their reasons, and puts forward four ways of infiltrating mathematical culture into middle school mathematics teaching. Create a good learning environment; Design a novel teaching process; Form a supervision and feedback mechanism.
