In the process of children's development, children are more likely to learn some knowledge and experience or form behaviors during these periods. If we miss this period, it will be difficult or even impossible to make up for it later.
0-7 years old is a critical period for children's brain development. Children's intelligence includes eight kinds: linguistic intelligence, logical or mathematical intelligence, musical intelligence, spatial or visual intelligence, sports or physical intelligence, interpersonal intelligence, internal intelligence or introspection intelligence, and natural observation intelligence.
There are individual differences in children's intelligence, so we should teach them in accordance with their aptitude.
