Enthusiastic netizens' primary school mathematics classroom teaching is the teaching of mathematics activities and the process of interaction and common development between teachers and students. Mathematics classroom teaching in primary schools should be closely linked with students' real life. Starting from students' life experience and existing knowledge, we should create vivid and interesting situations to guide students to carry out activities such as observation, calculation, guessing, reasoning and communication, so that students can master basic mathematical knowledge and skills through mathematical activities, learn to observe things and think about problems initially, and stimulate their interest in mathematics. Students are the main body of mathematics teaching, and teachers are the organizers, guides and collaborators of students' mathematics activities. Teachers should correctly understand the individual differences of students and teach students in accordance with their aptitude, so that each student can be fully developed on the original basis; To pay attention to students' learning process, we should not only pay attention to the development of students' general abilities such as observation, analysis, self-study, expression, operation and cooperation with others, but also pay attention to the development of mathematical abilities such as calculation, spatial concept, statistics and problem solving, and more importantly, pay attention to the healthy and harmonious development of students' emotions, attitudes and values. We should not only pay attention to the results of classroom teaching, but also pay attention to the process of classroom teaching. Mathematics classroom teaching in primary schools is a process in which teachers re-create the teaching content according to the concept and basic requirements of mathematics curriculum standards, on the basis of fully grasping the knowledge system, knowledge structure and writing intention of teaching materials, and according to the specific situation of students. Mathematics classroom teaching in primary schools is a comprehensive reflection of mathematics teachers' teaching skills, teaching ability, professional level, cultural accomplishment, educational viewpoint, teachers' morality and ideological quality.
