1 The actual needs of primary school mathematics education 1.1 The actual needs of primary school mathematics teaching: Students in primary school years of learning should have the following contents: understanding of numbers (such as integer, natural number, positive number, negative number, fraction, decimal) Knowledge of units and digits, knowledge of scores and fake points, knowledge of units of measurement and more. In the meantime, middle school students should also learn simple four arithmetic operations, calculation of graphics and space, calculation of statistics and possibility of data, and so on. These contents are easy to understand, adapt to and in line with the mental development of primary school students, but because of their scalability of knowledge points, strong permeability, and many complex
