With the advent of the information age, information technology has been widely used in mathematics classroom teaching. How to use PowerPoint (hereinafter referred to as PPT) effectively in mathematics teaching has received more and more attention. At present, there has been much research on it in China, however there is no complete overview and organized literature in this regard. This paper sorts out and summarizes the previous relevant studies and draws the following conclusions: (1) Previous studies on the usage of PPT in mathematics teaching mainly focus on three aspects: the value of PPT, the use of PPT and the use skills of PPT. (2) Previous research methods were single, and suggestions were mainly made through literature research, and the research conclusions were concentrated. The research on the value of PPT has not been deeply discussed and analyzed, so it lacks completeness. Most of the studies only focus on students, and there is no excessive and in-depth discussion on teachers' ability requirements. In addition, the research on the use skills of PPT has not been further implemented and verified, so the feasibility of the conclusion cannot be guaranteed. (3) There are still some gaps in the research on this topic. Most studies focus on the compulsory education stage, and there are few studies on the senior high school stage; Previous studies rarely discussed the disadvantages and shortcomings of PPT, and then did not discuss the problems that teachers should pay attention to avoid when using PPT; There are no relevant surveys and studies on students' attitudes towards PPT.
