The Dynamic Geometry Softwares (DGS) have brought much excitement into the computer-based teaching community, become more important in mathematics education in many curricula. As one of most remembered DGS, the Supper Smart Pad (SSP) can help many students to learn new knowledge effectively, to grasp knowledge easily. This paper discusses knowledge of dynamic geometry, introduces the free version of SSP in Chinese. It emphasizes on grasp new knowledge used and automatic reasoning in the SSP. It shows applications of the intelligent education software in mathematics teaching in the end. This paper also describes that the SSP is beneficial for instructions, especially for teaching students how to reason with the SSP.
