Teachers will also distribute homework in class. If you find similar problems in several papers, ask the children the reasons, give a few similar questions and see where the problems lie. Finding out the weak points in learning is the advantage of brushing the questions, but just brushing the questions is not enough. Find the problem.
In fact, the mathematics content of the second and third grades is not complicated, and it is easy to find out if children do not master the knowledge points. Only a small part of children's wrong questions are not mastered, and most of them are bad habits, including reading the questions carefully, standardizing writing, writing one question first and then writing another, and doing tests. The paper seems to be careless, but in fact, these good habits are not formed. These problems cannot be solved by brushing the questions. Someone needs to find it in time and gently point it out to the child so that he can realize how the mistake came from.
Brush the questions in the third grade and look at the target. If I think it's too early to cope with the school exam, it's enough to study math textbooks carefully and do well the questions issued by the school. If you expand your mathematical thinking, this kind of brushing is actually frustrating, successful and a lot of fun. Have a try with your parents.
