It is beneficial for students to form a global perspective and construct a complete knowledge system. This paper takes the initial lesson of the “Pythagorean Theorem” chapter as an example, exploring from a holistic unit perspective how to conduct the teaching of the initial lesson of a chapter, and proposes the conclusion: focus on overall design, clarify the main thread of the class;skillfully use context to lead, highlight the student’s position, to provide certain references for the teaching of the initial lessons of junior high school mathematics chapters.展开更多
