Infiltrate the mathematics culture into the comprehensive practical activities of primary school mathematics, the purpose is to enable students to use what they see and learn in their lives while communicating and cooperating and learning in the classroom, so that students should have a deep experience in the comprehensive practical activities. Mathematics culture has undergone thousands of years of precipitation, and the changes of the times have transformed into unique mathematical symbols and mathematical images. We need to understand and understand the cultural background of mathematics in mathematics in order to better understand mathematics. The value of the formation of unique mathematical ideas.

Key words: Mathematical culture, Synthesis and practice, Mathematical thinking
