Mathematics is the basic class, due to the mathematical concept of abstract, learn more boring. Electrified teaching is in line with children’s thinking characteristics and rules of understanding, is conducive to mobilizing students ’enthusiasm for learning, is conducive to students’ understanding and mastery of mathematical knowledge, a variety of senses to participate in activities, but also help to promote the development of student thinking. The following aspects of mathematics classroom teaching how to play the advantages of audio-visual media, improve teaching efficiency, talk about some knowledge and practices. First, before class, strengthen training. Provincial compulsory education primary school mathematics textbooks, with a mouth recording tape. Using this listening media before class, each lesson can not only change the traditional teaching method of reading and listening to students, but also attract students’ attention and improve listening efficiency.
