Small square commonly known as small squares (small cubes are also called small square, this article does not study), is commonly used learning tools, teaching aids. Supiao version of the primary school mathematics textbooks in the low, middle and upper grades are arranged fight, put small box activities, different levels, the purpose is also different. “Class standard ” revision is promulgated, the value of small box is particularly noticeable. What kind of teaching value? Teaching how to use small square? What are the new development value? This article try to explore one by one. First, the textbook layout and teaching essentials analysis SuYiao version of primary school mathematics textbooks were arranged in six volumes of books 10 times fight, put small square activities, of which there are three cases presented in the form of specific location and content are as follows:
