The new curriculum concept emphasizes that students are the masters of learning, and teachers are the organizers, guides and collaborators of students' learning, so students are the main body of learning. Learning activity is a process that students actively construct on the basis of existing knowledge and experience. The role of teachers should also be changed from a single lecturer to a new organizer, guide and collaborator, so that students can truly become masters of mathematics learning in teaching activities, and teachers should be changed from classroom controllers to classroom participants.

Second, constantly optimize the teaching methods suitable for students.

In the past, because of the bondage of exam-oriented education, students studied hard and teachers taught hard. In the end, students only solved the problem in the same way, but their ability to make and apply knowledge is quite low, not to mention their creativity. Examination-oriented education has seriously hindered the development of students' personality. In the usual teaching activities, teachers should learn to properly guide students to make some simple geometric figures with hard paper, wood strips, iron wires and other materials. It can stimulate students' interest in learning, improve students' practical ability, cultivate students' thinking ability and spatial concept, and help to improve students' mathematical quality in an all-round way. The arrangement of teaching materials is lively, illustrated, logical and simple, which will make boring mathematics knowledge lively, easy to accept, intuitive and inspiring. As long as we pay attention to creating suitable scenes in the teaching process, abstract problems will be visualized and inspired.

Third, carefully design the teaching process.

Classroom teaching behavior is an interactive process between teachers' teaching and students' learning, which requires two slaps. The new curriculum reform advocates students to adopt independent, cooperative and inquiry learning methods, which are organized and guided by teachers. To improve the efficiency of classroom teaching, teachers should pay attention to improving the effectiveness of classroom guidance. Therefore, teachers should carefully consider and design every link of classroom teaching.
