【Abstract】"Do you know" is a plate of Jiangsu textbooks, It is closely related with teaching content, it is an integral part of the teaching materials,and it is  an effective carrier of Mathematics cultural heritage. However, in practical work, many teachers have not recognized this part of the textbooks, only requires students to read it for himself, or even simply indifferent. This article attempts from Su Jiaoban elementary school math textbooks to analyze the content introducing、Layout and the use situation of "Do you know" section, moreover, investigate and understand common problems of the teaching of this plate, Thus explore and promote the effect of teaching strategies and methods about the "Do you know" section,give full play to its educational value, Let "Do you know" section become a bright spot in the mathematics classroom teaching and extracurricular activities.
