Cultivate students' sense of numbers: in teaching, students should be given enough time and opportunities to operate by themselves, establish the connection between the concept of numbers and the practical meaning they represent, understand the practical meaning of the concept of numbers, express numbers in various ways, grasp the relative size relationship of numbers in specific situations, abstract the quantitative relationship from practical problems, solve problems with what they have learned, and further learn various numbers and related operations. In the process of exploring and solving mathematical problems, and in the process of communicating with others, we can enhance our understanding of quantitative relations and their changing laws, and further develop our sense of numbers.

The role of number sense: Mathematical knowledge is everywhere, but how to link different disciplines can play an integrated role to some extent.
The expression of number sense as perception reveals the dual attributes of this concept: both feeling, such as perception, and enlightenment, such as understanding. Feeling is produced by external stimuli acting on the theme, and it is thought through the body rather than the brain. It contains primitive and empirical elements. Consciousness is the subject's own, and it is produced through brain thinking. Perception is through the body and brain, so both perception and thinking have components. Mainly in three aspects: the perception of logarithm and quantity; Perception of quantitative relations; Understanding of the estimation of operating results.
