Learning mathematical concepts is very important for students to develop their core mathematics competency. Atpresent,there are many misunderstandings in the teaching of mathematical concepts. This paper starts with the importance of coremathematics competencies and mathematical concepts and analyzes the reasons for the problems arising from the present teachingof mathematical concepts. From the introduction, the establishment and the consolidation and application of mathematical con-cepts, this paper analyzes and demonstrates the actual cases, guides the students to return to the origin of mathematics,and findsthe essential features, connotation and extension of mathematical concepts, which can enlighten the classroom teaching.
