Since the advent of the 21st century, the continuous development of the Internet has had a great impact on the thinking, study and life of the students in school. It also poses some challenges to the traditional educational mode of work. At the same time, computer functions are more and more, to meet people’s more needs. Practice has proved that the use of computers in primary school mathematics professors can significantly improve the efficiency of primary school mathematics classroom, and can be active classroom atmosphere, giving students a relaxed and stress free student atmosphere, so teachers can use CAI to make the elementary school mathematics classroom full of happiness.
