Learning a subject, we must grasp the essence of the subject, the core concept of “ordinary high school mathematics curriculum standards” that: teaching should emphasize the basic concepts and basic ideas of understanding and mastery, for some of the core concepts and basic ideas to run through Mathematics teaching has always been to help students gradually deepen understanding.1 Therefore, the concept of mathematics teaching in high school mathematics teaching occupies an extremely important foundation position, is to learn the basics, master the basic skills, the formation of basic ideas, the accumulation of basic activities experience Premise, but also to promote the development of student thinking an important teaching process.In the reality of high school mathematics concept teaching, some teachers ignore
