Sense of number refers to the number and quantity, the relationship between the number and calculation of estimates and other aspects of sentiment. It is the core concept that must be followed in mathematics teaching, mainly in the curriculum of “synthesis and practice” and “number and algebra”. Through the analysis and exploration of the number sense training in primary school mathematics, the author puts forward the strategies and suggestions for effectively raising the number sense of primary school students.
