The principle of mathematical sociality generally refers to the principle of systematic sociality. Systematic social principles belong to the ontological category of slow mathematics education goals. According to Qian Xuesen's system theory, a system is an organic whole with specific functions, which is composed of several elements connected in a certain structural way. Holistic attribute is the most basic feature of the system, holistic thinking is the basic unit of system movement, and holistic concept is the core idea of the system. As the core element of the slow education system in mathematics classroom, the teaching goal should have multiple overall functional characteristics of shaping social people, not only in cognitive skills and ideological experience, but also in positive emotions, noble beliefs and aesthetic attitudes.
