The practice of the combination of number and form in the teaching of junior high school mathematics exercises

摘要

the combination of number and shape is an important mathematical thought. It plays an important role in making abstract knowledge and mathematical theory concrete and vivid. It is an effective idea for students to learn mathematics well. With the implementation of the new curriculum reform，the idea of combining mathematics is more and more widely used in junior high school mathematics. Many teachers can infiltrate this concept according to specific teaching needs. This paper mainly discusses the practice of the combination of number and form in junior high school mathematics teaching，and discusses the integration method of the thought of the combination of number and form in teaching from the perspective of development，so as to improve the effectiveness and effect of teaching，promote the better application of the combination of number and form in teaching，and give better play to the growth role of students.
