Instructional design is a pre-class plan for classroom teaching.It is a more complicated intellectual activity and an integral part of the teaching system.One of the important contents of it is to design in line with “purpose” and “ Regularity ”of teaching, that is, on the one hand to make all aspects of the classroom teaching structure are closely around the core of a class of knowledge, to demonstrate the occurrence and development of knowledge process; on the other hand to analyze the psychological characteristics of students According to the characteristics of junior middle school mathematics knowledge and the characteristics of junior middle school mathematics teaching, the structure of junior high school mathematics classroom teaching is generally divided into three parts: construction activities, mathematical concepts
