This paper examines the number shape union thought in Chinese traditional mathematics embodiment， beginning with the analysis of the development of geometry in ancient China the number shape union thought the definition and development of history，" number" and "the form" as a form of mathematical knowledge， inspiring a number form， several considerations and greatly enriched shape， two are not to be separated， relying on each Throughout the development of geometry in ancient China， the number shape union thought main value is embodied in two aspects: problem solving method and theory validation The number shape union thought is in problem solving and development， in the course of development， gradually found the number shape union general， using graphics to verify the theoretical correctness and is not rational and intuitive way， avoids mathematical concept symbols dry， easy to Next， the article illustrates the number shape union thought to the development of geometry in ancient China brought brilliant success， today， the number shape union thought was more commonly used， in mathematics teaching in middle school， the number shape union method becomes the teacher and the students to solve the problem of effect is good， practical
