With the rapid development of science and technology in today's world, the information age has entered our life and campus. The development of modern information technology has a great influence on the value, goal, content and learning method of education and teaching. A basic idea of mathematics curriculum after curriculum reform is that the development of modern information technology has had a great influence on the value, goal, content and the way of learning and teaching of mathematics education. The design and implementation of mathematics courses should attach importance to the application of modern information technology, such as calculators and computers. Taking modern information technology as a powerful tool for students to learn mathematics and solve problems, we are committed to changing students' learning methods so that students are willing and have more energy to invest in realistic and exploratory mathematics activities. The integration of modern information technology and primary school mathematics curriculum can realize the reform of teachers' teaching methods, students' learning methods and teaching content presentation methods, and make information technology a tool for teachers to strengthen the pertinence, vividness and effectiveness of teaching, and for students to know, explore and solve problems, thus improving students' learning level and efficiency and improving the quality of primary school mathematics teaching.

I. Understanding of information technology and integration

The broad understanding of information technology is: the technology to complete the functions of information acquisition, transmission, processing, regeneration and use. From the perspective of education, information technology can be regarded as a part of educational environment or educational means, which can be used to improve education and teaching and promote the reform and development of education.

Integration refers to the process of constructing and programming some related parts or factors into a new unified whole. As a result, all the elements of the system are coordinated and infiltrated, and the system gives full play to its role. The understanding of integration can be said to be a hundred schools of thought contend today, and each has its own theory. Professor He Kekang of Beijing Normal University described it as: by effectively integrating information technology into the teaching process of various disciplines, creating a new teaching environment and realizing the teaching and learning mode characterized by "autonomy, inquiry and cooperation" can not only give play to the leading role of teachers, but also reflect the main position of students, thus giving full play to students' initiative, enthusiasm and creativity, making fundamental changes in the traditional teacher-centered classroom teaching structure and truly cultivating students' innovative spirit and creativity.

Second, the integration of information technology and primary school mathematics has created a new milestone in primary school mathematics teaching.

Classroom teaching is a complex dynamic system composed of many factors, and it is the main channel to improve teaching quality, promote students' development and implement quality education. Under the new situation, the development of modern information technology has a great influence on the value, goal, content and teaching and learning methods of classroom teaching, and is also profoundly affecting and changing the classroom teaching of primary school mathematics. The integration of information technology and primary school mathematics teaching is guided by information technology, system theory and educational teaching technology theory, and based on the law of primary school mathematics teaching, so as to realize the information teaching idea of integrating all elements of information technology system with teaching and learning system, analyze, study and solve problems in subject teaching with a holistic, connected, developing and changing viewpoint, overcome contradictions that were difficult to solve in the past, and truly realize the integration of teaching objectives, democratization of teaching process and diversification of teaching methods and technologies. Its purpose is to learn and use information technology effectively in primary school mathematics teaching, to promote the changes in the presentation of teaching content, students' learning methods, teachers' teaching methods and the interaction between teachers and students, to create a diversified learning environment for students, to make information technology truly become a tool for students to understand, explore and solve mathematical problems, and to cultivate students' information literacy and ability to explore and solve problems independently by using information technology.

The development of primary school mathematics teaching in the new period is facing new opportunities and challenges. The application of novel and advanced educational technology can provide a broad display platform for the new growth point of primary school mathematics teaching. Therefore, studying the integration of modern information technology and primary school mathematics teaching is conducive to changing educational concepts, reforming classroom teaching, updating teaching methods and means, and promoting the overall reform of educational concepts and teaching mechanisms, which has profound practical significance. The core of integration is to integrate modern educational technology into primary school mathematics teaching. In teaching practice, we can use technical means to obtain text, images, sounds, animations, videos, even 3D virtual reality and other information to make courseware, which can enrich teaching capacity, enrich teaching content and make teaching methods more diverse and flexible. Effective integration and application is more conducive to creating a new world of primary school mathematics teaching and bringing a new revolution to primary school mathematics teaching, which is another new milestone in primary school mathematics teaching.

Third, find the breakthrough point of information technology and primary school mathematics teaching, and the classroom will shine brilliantly.

Integrated teaching of information technology combines traditional teaching methods (teachers' teaching language, blackboard writing, teaching wall charts, text illustrations, experimental instruments, model specimens, etc.). Cooperate with audio-visual teaching means (slides, projection sound, video, computer, etc.). ) according to the actual teaching materials, so as to serve the overall teaching objectives and achieve the best teaching effect. The organic combination of primary school mathematics and information technology is first considered from the essential characteristics of primary school mathematics teaching and its teaching form. Primary school mathematics teaching attaches importance to classroom goal consciousness, organizational control consciousness, emotional consciousness, feedback and error correction consciousness, evaluation consciousness and students' participation consciousness, and highlights students' teaching activities. This kind of teaching obviously requires large capacity, fast pace and circular feedback in teaching, and attaches importance to bilateral activities between teachers and students. The application of modern information technology in primary school mathematics teaching can really give play to the leading role of teachers in classroom teaching, realize the optimization of teaching process, make students get the best learning effect, and break the traditional teaching habits and routines in which teachers dominate the whole teaching process and put students in a passive position.
