Good interest can make people have a positive cognitive tendency, so as to promote students to explore new knowledge, ability development, the formation of a good personality. Strong interests often make students have a strong desire for knowledge of unknown things. “Those who know better than the good, those who are better than the music ” This fully illustrates this truth. Therefore, in mathematics classroom teaching, only by arousing the interest of students can we effectively improve the teaching quality and change the shortcomings of “high efficiency and low energy” in traditional mathematics teaching. In mathematics classroom teaching, how to arouse the interest of students, need teachers
