In order to let children start early, many parents hope that their children can read more books and do more arithmetic in kindergarten. In fact, they put pressure on their children too early, which may cause them to be tired of learning. In learning, children should focus on games, because for children aged 3-6, the main purpose of entering kindergarten is to gain cognitive, emotional, social and physical training, rather than what knowledge they have to learn. But now many parents attach great importance to kindergarten skills education, such as bilingualism, arithmetic and so on, but in fact this awareness is not correct. The function of kindergarten is to perform the tasks of conservation and education normally. What knowledge children aged 3-6 should learn should be based on the Kindergarten Education Outline and the Kindergarten Education Guidance Outline. For example, some parents will be surprised to hear about the arithmetic problem that everyone cares about, because the learning goal of kindergarten children in mathematics is to complete the addition and subtraction within 10. But now some kindergartens or training institutions teach addition and subtraction within 10 in small classes, and addition and subtraction within 100 in large classes. In fact, this is beyond the scope of children's study. They do it to cater to the psychology of some parents. . But even if the child can think of it, it often only forms a conditioned reflex, but if it is an application problem, the child will not understand it.
