First, understand the basic concepts of the new curriculum standard and use teaching methods flexibly. Second, grasp the overall goal of the new curriculum. Third, how to realize the new curriculum standards and complete the teaching tasks in teaching? First of all, follow the principle that effective teaching activities are the unity of students' learning and teachers' teaching, students are the main body of learning and teachers are the organizers, guides and collaborators of learning. In classroom teaching, we should stimulate students' interest in learning, arouse their enthusiasm, stimulate their mathematical thinking and encourage their creative thinking; Pay attention to cultivating students' good teaching and learning habits and let them master appropriate teaching and learning methods. Secondly, cultivate students to listen carefully, think boldly and actively, practice with hands, be brave in independent exploration, and cooperate and communicate happily. Students' learning is a vivid, active and personalized process. Students should have enough time and space to experience activities such as observation, experiment, guess, calculation, reasoning and verification. Finally, teachers' teaching should be based on students' cognitive development level and existing experience, face all students and pay attention to heuristic and personalized teaching. Teachers should play a leading role, properly handle the relationship between teaching and students' autonomous learning, guide students to think independently, actively explore and cooperate, so that students can understand and master basic mathematical knowledge and skills, experience the application of mathematical ideas and methods, and gain basic experience in mathematical activities.
