Virtual reality technology (referred to as VR technology) as a new generation of information technology has brought new opportunities for the development of the education industry. The three basic features (immersion, interaction, and conception) of VR technology complement the boring, abstract and logical aspects of mathematics teaching and learning. The combination of VR technology and mathematics teaching can make abstract and complicated mathematical formulas, models, algorithms, graphics intuitive and concrete, which is convenient for students to understand and accept, thus enhancing students' interest in mathematics. At present, there are many successful cases combining VR technology with teaching. The combination of VR technology and automobile professional education can make up for the shortage of teaching funds, and combining VR technology with medicine can improve the cure rate of patients, etc. However, the application of VR technology in mathematics teaching has rarely been reported. This paper will start with the combination of VR technology and mathematics teaching, aiming at improving students' interest and efficiency in learning mathematics, and improving the research gap of the combination of VR technology and mathematics teaching.
