The introduction of new courses is an important part of classroom teaching, a course must be accompanied by a wonderful new class into.

This article talks about the introduction of several new courses in high school mathematics teaching. First, the warm new knowledge, review Old knowledge system is the characteristics of mathematics, students need to build the mathematical system with the existing cognitive system of students. Therefore, before teaching new knowledge, teachers lead students to briefly review the old knowledge, and then use it as a basis for asking new questions. This is not only for students
