Students are the object of education and the master of learning. They are the main body of understanding and transforming the world. Teachers should focus on strengthening students' subjective awareness of learning, change from "learning from me" to "I want to learn" and invest in training as a master. In mathematics teaching, teachers should establish the teaching structure of autonomous learning activities, guide students correctly and skillfully, so that students can actively participate in the whole process of learning and get success and happiness in the process of learning. In teaching, I constantly stimulate students' autonomy, make them independent from the perspective of thinking, make students have clear goals and participate in depth, and students have ample opportunities to show their learning ability. Make the process of learning mathematics gradually become the activity process of students' self-control, self-regulation and self-control, and at the same time make independent exploration become a powerful fulcrum of students' personality autonomy. Let students fully realize the happiness of acquiring knowledge independently, enhance the initiative of learning and improve their interest in learning. And let students actively seek the best method in their usual exercises, so that their mathematical ability can be improved rapidly. At the same time, I am good at discovering and guiding students' thinking methods, so that students can understand and improve their understanding and get the best way of thinking.
