A more effective set of "books" is the logic dog textbook. My baby started playing when he was two years old, and the effect was good. It is for children to learn while playing. If there is something suitable for older children, you can go to the bookstore and ask. That set of books pays more attention to the early development of children's logical thinking, practical ability and creativity. In the course of my son's study, I always let him read the topic first and understand it before doing it, which invisibly increases his ability to understand the text. You can teach him new words by the way, which increases his literacy ... As for emotional books, the most effective thing is stories. You can weave some stories to guide your child according to his current specific situation, and even let him pick up the end of the story, which is a particularly good exercise for him (imagination and writing ability). In short, I personally think that as long as you are a mother's multi-purpose snack, everything can be used as a tool to educate children. Just what do you think of preschool education when the child is five years old? I hope everyone will not go into the misunderstanding of preschool education. At this time, parents have begun to instill the first and second grade courses into their children in advance, which is a very annoying thing! The result must be not worth the loss.
