Give an example in a book every day from Monday to Friday. If you do it right, let him play. Don't force children to study all the time. The child will want to sit here after eating anyway, and then he will passively resist and not work. After a long time, you called him stupid, so he borrowed the donkey from the slope and let it go. I am stupid and I don't study. Let him go only if the question is right. Choose a small one on the first day, and then it will become more and more difficult, so that he will think that you keep your word. Your question is not that simple. You have to refuel before you have a chance to play games.
On the other hand, did children play too little when they were young? Children are learning the empirical truth extracted from life. Without life practice, it is not normal for children to have nothing in their minds. You have to take him to play. Globes, magnifying glasses, drilling holes and so on.
Which one was played before, and then the teacher said the same thing in class, and what you said appeared.
