Ancient children's multi-university arithmetic

Ancient children could learn arithmetic at the age of 8.

According to Bao Bo, ancient people left home at the age of eight to study small arts and perform small tasks. It means that ancient children will go to primary school at the age of eight to learn literacy, arithmetic and some manners to treat people.

Bao Bo, a book by the great Dai Li, continued: Go to college with a bunch of hair, learn great art, and complete great festivals. The meaning of this sentence is that children will go to college when they are adults. The content of study is shooting and fighting. This kind of fighting does not mean driving a carriage (driver's license), but he can still shoot at the target with a bow and arrow in a galloping chariot, which is much more difficult than driving. The ceremony of the temple fair means entering the level of national governance.

Arithmetic education

Modern elementary mathematics education can be said to have started after the promulgation of Guimao academic system (1903), the abolition of imperial examinations and the establishment of primary and secondary schools in the late Qing Dynasty. At that time, there were arithmetic classes in primary schools and mathematics classes in middle schools (including arithmetic, algebra, geometry, trigonometry and bookkeeping).

In the early years of the Republic of China (1912 ~1913), the academic system of "not letting children learn from ugliness" was announced, and the middle school was changed from five years to four years, and bookkeeping was no longer taught in mathematics courses. The longest implementation is the Ren Xu school system announced by 1922, which changes primary and secondary schools to six years, with two grades in junior high school, four years in junior high school, two years in senior high school and three years in junior high school.

Junior high school mathematics teaches arithmetic, algebra and plane geometry, while senior high school mathematics teaches plane triangle, senior high school geometry, senior high school algebra and plane analytic geometry (senior high school is divided into arts and sciences, and some science subjects add solid analytic geometry and preliminary calculus). This academic system has basically been used 1949.

After the founding of People's Republic of China (PRC), the primary and secondary education was reformed, and the educational system was changed to six years in primary school, three years in junior high school and three years in senior high school, and the arithmetic course was gradually abolished in junior high school. In 1950s, the teaching of plane analytic geometry was stopped in high school mathematics, and then the basic knowledge of calculus, probability theory and computer was restored and increased.
