Under the development trend of educational informatization, how to change mathematics teaching in primary schools?
China's economy and society are developing rapidly, and social life is changing with each passing day. Today, information technology has penetrated into all fields, and mathematics education is also facing severe challenges in the information age. Traditional classroom teaching has gradually exposed many weaknesses, such as the principle of teaching students in accordance with their aptitude is difficult to implement under the premise of class collective teaching activities, and the expression based on language narration makes it difficult to transmit and receive some teaching information. The integration of information technology and mathematics education will be an important topic and even a basic principle of mathematics education in the new century. With the connection of Internet information, we should give full play to the advantages of information-based teaching, provide a colorful educational environment and powerful learning tools for students' learning and development, and enrich their horizons. Based on my experience in front-line teaching in recent years, this paper talks about the role of educational informatization in primary school mathematics classroom.

First, educational informatization can stimulate students' interest in learning.

Psychological research shows: "Children have their own personalities, and their activities are dominated by their needs and interests. All effective activities must be based on certain interests. " Therefore, interest is the best teacher for students. Information technology has the characteristics of comprehensive processing of text, graphics, sound, images and animation. And powerful interaction. A series of computer-aided teaching courseware and CD-ROMs in various disciplines can fully create a vivid and vivid teaching environment, and provide vivid expression tools for the smooth implementation of teachers' teaching. Only by letting children like the classroom from the heart can they be considered as good education. For example, in concept teaching, computers can create inspiring teaching situations, design mathematical experimental environments for students to do mathematics, stimulate students' interest, build new teaching models, increase information and improve teaching efficiency. For example, People's Education Edition 20 12, the first volume of Grade One, P9, introduces short stories with multimedia courseware when learning. As a teacher, if we just read books by the book, it will not only waste the time of teachers and students,
