Mathematics is a kind of thinking, description, characterization, explanation, understanding and application of the real world. Its purpose is to discover some mathematical laws contained in the real world and serve the progress of society and the development of mankind. Mathematics is a very beautiful field, because the main part of mathematics is created and constituted by the human mind. Mathematics is closely related to the development of science and technology, humanities and economy. "Mathematics comes from life and is applied to life." There is a lot of mathematical information in the world around us, and mathematics is also widely used in the real world.

Interest and confidence in learning mathematics are very important issues for students. Teachers should combine students' life with mathematics learning, let familiar and close life enter students' vision and mathematics classroom, make mathematics teaching materials concrete, visual and intuitive, let students feel and discover the role and significance of mathematics, learn to observe the objective world around them with mathematical eyes, and enhance the consciousness of mathematics function.

Mathematics is closely related to the real world. Applying mathematical knowledge to practice can not only develop students' thinking quality, but also make students feel that "mathematics is interesting", "mathematics is reasonable" and "mathematics is useful" in the process of learning and application, thus enhancing primary school students' self-confidence in learning mathematics, allowing primary school students to learn to feel the rationality of mathematics with their own life experience, and realizing the harmonious synchronization of mathematics learning and life experience.
