After the summer vacation, the children will be in the fifth grade, and they are not very good at math. Is it necessary to go to a remedial class?
In fact, there is no need to make up lessons in the fifth grade. I suggest you observe whether he likes to make up lessons. If he doesn't make up lessons, it will aggravate his dislike of mathematics and even stop studying. If he is in the fourth grade, I suggest you let him make up lessons. It's too early now, and we can make up elementary school math for him.
