In order to achieve good teaching objectives, teachers' preparation work is very important, including: ① the determination and description of teaching objectives should have the content of mathematical culture infiltration; (2) Make clear the places where mathematics culture can be infiltrated in the current mathematics textbooks, so as to facilitate the processing and compilation of the textbooks; ③ The main teaching behavior of infiltration and selection of mathematical culture; ④ The formation of teaching plan, etc.

2. The infiltration strategy of mathematical culture in life.

Mathematics should strive to restore and reproduce the process of mathematics and let students experience the process of knowledge generation, formation and development, which is of great practical significance to consolidate students' mathematical culture. The infiltration of mathematical culture should also emphasize the teaching implementation strategy of combining mathematics with life, learning mathematics in life and activities, and feeling mathematical culture.
