1, first of all, we should face up to the problem and actively seek solutions. If children's math scores in the third grade have been hovering below 90 points, then parents really need to pay attention. After all, the difficulty of mathematics learning for junior three children is still relatively small. If the third grade is below 90 for a long time and measures are not taken in time, the decline in grades will be more serious after the fourth grade.

2. Secondly, suit the right medicine, and the effect is more obvious. Mathematics in grade three is actually not difficult. Relatively speaking, the knowledge points are relatively simple and not too complicated. If the child's grade is always 86, then parents should first observe the reasons for the problems in the child's grade.

Finally, get rid of bad study habits. Some children, especially those who are active and jump out, are impatient. If their study habits are not particularly good, their grades will be difficult to stabilize.
