Carelessness is not just learning, but learning first. Carelessness is actually the reason why the mastery of the problem is not sufficient, that is to say, what he has mastered is unreliable. Maybe if you ask him a theorem, he will give you such an answer, and he will not be sure himself, especially if you add a question to his answer? When he was studying, he was even more uncertain and not solid. When he studies in the future, you just ask him to ask himself more reasons. Don't take everything for granted. In fact, you can imagine that your child is actually very smart, and the smarter the child, the easier it is. Because he has a strong understanding ability, he doesn't pay attention to review and deepening after learning. You should help him ask a few more reasons, and it will be solved. It's actually very simple to tell me something about you.

Here are the health problems. If a child is not careful, it is called "blood is not raised" in Chinese medicine. What does this mean? You are a child, I think it should be a word that is not too high, and the word is definitely not high among peers. At this time, his hematopoiesis will be less than that of his peers, because his bones are small and his bone marrow will be less. However, when people think, what do they rely on? Blood provides energy to maintain brain supply. I suggest you switch to teaching. Pay attention to children's health. Your child, I estimate, can do things easily in three minutes. Because his brain has less blood supply than his peers, he will suffer physically and mentally, but he is also doing the same thing with his peers. This is definitely inefficient. Pay attention to his health. It is useful to supplement calcium or something. I hope it helps you.
