The basic starting point is to promote students' all-round, sustained and harmonious development. We should not only consider the characteristics of mathematics itself, but also follow students' psychological laws in learning mathematics, and emphasize that starting from students' existing life experience, students should experience the process of abstracting practical problems into mathematical models and explaining and applying them, so that students can gain an understanding of mathematics and make progress and development in thinking ability, emotional attitude and values.

Mathematics education is open to all students.

Everyone learns valuable mathematics; Everyone can get the necessary mathematics;

Different people get different development in mathematics.

The content of students' mathematics learning should be realistic, meaningful and challenging, which is conducive to students' active observation, experiment, guess, verification, reasoning and communication.
