Abstract: University clubs are a requirement for innovation in talent cultivation models and the reform of the“student-centered”teaching philosophy based on the OBE. The construction of clubs is of great significance, as it further subdivides the two classrooms advocated by traditional classroom teaching into three classrooms and becomes a key link connecting the three classrooms. After three years of club teaching practice, students have achieved a lot in participating in various competitions, fully demonstrating that innovative teaching in mathematics clubs is a good model for cultivating students' mathematical knowledge and skills.

Key words: Club, “Student-centered”, OBE teaching philosophy, Three classrooms, “Three comprehensive education”, Competition
