The external stimuli provided by information technology are comprehensive stimuli of various senses. They can not only see (visual), hear (auditory), but also manipulate with hand (sense of touch), which is more stimulative than single Listen to the teacher to explain much stronger. At the same time, the richness, interactivity, vividness, vividness, controllability and participation of information technology greatly enhance this sensory stimulation, which is very conducive to the acquisition and maintenance of knowledge. First, the intangible is tangible. Junior high school mathematics rational knowledge is too heavy, the traditional teaching only one-sided emphasis on logical thinking training, lack of adequate graphics support, lack of exploration for students
