A child's intelligence, like a seed, needs conditions to germinate and grow. This condition is massive reading and hands-on games.
If a child has never read a good book, or even a book with more than 654.38 words, but spends a lot of time on school textbooks and a lot of homework, then the child's talent and intelligence will starve to death early.
The focus of primary school is not on grades, but on reading. Ignoring reading in primary school is a great loss to children's future development
This kind of loss began to appear in junior high school. Many middle school teachers know a strange phenomenon: those children who get high marks only by investing all their time and energy in primary school, their grades drop rapidly after entering junior high school, and the more they learn, the more tired they are, the less they will learn; It is precisely those children who have average grades in primary school but are well-read and well-informed, with strong grades and great potential.
This situation is even more serious in high school. After entering the society, when a person's development needs work ability instead of report card, this differentiation is even more extreme.
