1. Optimize the teaching content and excavate the teaching materials reasonably. Research shows that when mathematics is closely combined with students' real life, mathematics is alive and full of vitality, and students' interest in learning and solving mathematical problems can be stimulated. Therefore, teachers should pay attention to students' experience and interest in teaching, endow them with rich realistic background of mathematics knowledge, and provide vivid and practical learning materials for students' mathematics learning. At the same time, teachers should dare to "break through" the shackles of existing textbooks, adapt textbooks according to students' reality, and optimize learning materials;

2. Close to students' life and create an interesting situation "Interest is the best teacher". Teachers should be close to the reality of students' life, actively create natural and vivid situations, improve their interest and light up the math classroom. Making use of students' nature of loving games and innovating learning methods not only make students happy and get good grades, but also exercise their cooperative inquiry ability.
