Emphasizing the development of students divergent thinking, so that students move to the classroom back to the students, has become the guiding ideology of new textbooks. By creating good mathematics activities to guide students to better construct and improve their mathematical quality in their own and positive mathematics activities, it is a good teaching method. First, to help students produce interest and desire to learn
