Mathematics is closely related to the life of primary school students. Therefore, mathematics teachers should improve the core quality of primary school students with the help of experiential teaching. It is necessary to start from the actual life of primary school students, so as to guide primary school students to actively and deeply think about mathematics problems. First of all, teachers should be based on the perspective of primary school students, comprehensive consideration of primary school students' understanding ability, learning ability and other comprehensive problems, and then related to the actual life to carry out mathematics education. Secondly, when teachers create life-oriented teaching situation for students, they should pay attention to promote students' divergent thinking, which not only strengthens their understanding and knowledge of mathematics teaching knowledge, but also helps to cultivate and improve the students' ability to apply mathematics knowledge. For example, when learning "statistics", teachers can create a life-like teaching situation for students. With the "class students' interests and hobbies" as the theme, the teacher sets several options for the students, and encourages the students to make choices. After that, the students are guided to conduct statistics on the number of students with different interests and hobbies according to the actual situation.
