You can buy copybooks to teach him to practice (you can remember the stroke order and phonetic order). Don't force math problems, but relax, such as practicing calculation problems more and adding some small rewards to make children motivated. If he can't, teach them patiently, don't rush and don't scold them. Also, today's children should pay attention to their eyes, don't be nearsighted, and look at the distance once an hour and a half. In fact, I have no experience myself. I hope parents can think about whether my opinion is feasible before taking it. )
