Cases talk about the concept of teaching in the junior high school mathematics classroom implementation Contains a large number of mathematical concepts in the middle school mathematics concept is the basic element in the system of mathematical knowledge, the teaching of mathematical concepts and thinking ability of the students to the concept of culture are closely linked. Textbooks under the new curriculum standards, have changed their old textbooks strict knowledge structure and rigorous system of mathematical concepts, a description of the concept of general no longer special attention to the form of its expression, and pay attention to new curriculum standards emphasize “concerned with the concept of the actual background of the formation process of mechanical memory to help students overcome learning way. “author teaching mathematical concepts have done some Chuqian exploration, now and share with everyone.
