The educational significance of mathematical activities lies in that students gain perceptual knowledge, emotional experience, mathematical consciousness, mathematical ability and mathematical literacy with individual characteristics by personally experiencing the process of mathematical activities. The formation of students' wisdom depends not only on mastering rich knowledge, but also on practice and gaining experience in practice. Mathematical thought is not only formed in exploration and deduction, but also accumulated in mathematical activities.
The "four bases" are an organic whole, which are interrelated and promote each other. Basic knowledge and skills are the main carriers of mathematics teaching, which need to spend more classroom time; Mathematical thinking is the essence of mathematics teaching and the main line of classroom teaching; Mathematics activity is an indispensable teaching form. While paying attention to basic knowledge and skills in teaching, we should also pay attention to the cultivation of students' basic mathematical thoughts, and pay attention to students' participation in basic mathematical activities and understanding of basic activity experience. This kind of teaching has a positive and long-term impact on students' physical and mental development.
