If the child gets 87 points in the seventh grade math exam, it means that he has made some achievements, but there is still room for improvement. You can work with your child to analyze what he has done well and what needs to be strengthened, help him make a scientific study plan and improve his math scores. Here are some suggestions:

1, check for missing parts: find out the weak links in children's mathematical knowledge system and conduct targeted explanation exercises one by one until they are proficient.

2, consolidate the foundation: for the knowledge that has been mastered, it is necessary to consolidate it repeatedly, making it the basic kung fu of children.

3. Exercise thinking: Mathematics is not only a skill of memory and operation, but more importantly, it is to cultivate children's logical thinking and problem-solving ability. Children's thinking level can be improved through some thinking training games and math problems suitable for children.

4. Selection of tutoring materials: According to the actual situation of children, choose targeted and interesting math textbooks or tutoring books to help children improve their math scores in a relaxed and happy atmosphere.
