Why does the sum of mathematics credits in the first grade of primary school work? Why?
The main purpose of getting credit for mathematics in grade one is to lay the foundation for the ten-point method to be learned later, and its ultimate goal is to improve the operation speed of oral calculation.

Primary school mathematics is to teach children a series of knowledge about number, four operations, the calculation formula of figure and length, unit conversion and so on through textbooks, which lays a good mathematical foundation for junior high school and daily life calculation.

Therefore, learning while doing and learning while playing will make children learn more actively. From the perspective of educational objectives, while imparting knowledge, we should pay more attention to cultivating students' comprehensive abilities such as observation, analysis and application.
