Mathematics teaching activities must be based on students' cognitive development level and existing knowledge and experience. Teachers should stimulate students' enthusiasm for learning, provide them with opportunities to fully engage in mathematical activities, and help them truly understand and master basic mathematical knowledge and skills, mathematical ideas and methods in the process of independent exploration and cooperative communication, so as to gain rich experience in mathematical activities. Students are the masters of mathematics learning, and teachers are the organizers, guides and collaborators of mathematics learning. First of all, the new curriculum requires teachers to change from traditional knowledge givers to organizers of students' learning. The organizer is a teacher who wants to create an independent, exploratory and cooperative space for students. The meaning of organizer should be to organize students to discover, discover, collect and use learning resources. Establish a humane, harmonious, democratic and equal teacher-student relationship, so that students can be inspired and encouraged in an atmosphere of equality, respect, trust, understanding and tolerance; Organize students to create and maintain a positive psychological atmosphere in the classroom and learning process. Second, teachers are the leaders of learning activities. Modern teaching theory holds that the essential attribute of education is the dialectical unity of teachers' value guidance and students' self-construction. Teachers should be students' guides. The significance of learning guidance lies in guiding students to design appropriate learning activities, further exploring their predecessors' experience, and guiding students to realize the super-level play of curriculum resources value. Teachers should stimulate students' enthusiasm for learning, provide students with opportunities to fully participate in teaching activities, and help them truly understand and master basic knowledge and skills in the process of independent exploration and cooperative communication. The characteristics of guiding learning are containing without revealing, pointing without knowing, opening without reaching, and introducing without sending. The content of guidance includes not only methods and ideas, but also the value of being a man. Guidance can be manifested as enlightenment. When a student gets lost, the teacher will not tell him the direction easily, but guide him to identify the direction. Guidance can be expressed as an incentive. When students are afraid of climbing mountains, the teacher does not drag them to climb together, but lights up his inner spiritual strength and encourages him to keep climbing. Third, teachers are partners in students' learning activities. Teaching process is a process in which teachers and students create students. Teachers and students are both components of the curriculum, and they participate in teaching on an equal footing with students and become partners in students' learning activities. Share your feelings and knowledge with students, seek truth together, and dare to admit your mistakes and mistakes. The new curriculum requires teachers to change from "teacher-centered", condescending and performance-oriented instructors to collaborators in constructive learning. Therefore, teachers should break the old concept of "teacher-centered", guide students to express freely and explore independently in a democratic and equal learning atmosphere, and let teachers walk out of the shelf of "dignity as teachers" and move from condescending authority to equal chief.
