At present, it is in the period of curriculum reform. Various related attempts have been made by the relevant curriculum preparation organizations. There are several different versions of mathematics teaching materials. These versions all have a common characteristic in the treatment of mathematical concepts. They no longer emphasize the strict definition of the connotation of mathematical concepts. The emphasis is on describing concepts in living languages, recognizing concepts through images and intuitive illustrations, The extension describes the concept of understanding. This mathematical concept is not strictly defined, how to teach mathematics concepts, so that students can accurately understand and correctly understand the connotation and denotation of concepts in classroom teaching, pay special attention to this issue, I think the teaching of mathematical concepts Pay attention to the following five aspects:
