1. Cultivate children's interest in mathematics. Parents can tell stories and play games, so that children can feel the fun of mathematics, thus stimulating their interest in mathematics.

2. Help children to establish mathematical thinking. Parents can help their children to establish mathematical thinking and improve their logical thinking ability through some simple math games and exercises.

3. Encourage children to do more questions. Parents can encourage their children to do more Olympic math problems and improve their problem-solving ability through continuous practice.

4. Help children sum up experience. Parents can help their children sum up their experience in solving problems, let them learn from their mistakes and constantly improve their ability to solve problems.

5. Provide a good learning environment for children. Parents can provide their children with a quiet and comfortable learning environment so that they can concentrate on their studies.

6. Keep in touch with the teacher. Parents should keep in touch with their children's teachers, learn about their children's learning at school, and solve problems in time.

In short, parents should pay attention to cultivating their children's mathematical interest and thinking ability when tutoring their children's Olympic math problems in primary schools, and help them improve their problem-solving ability through continuous practice and summing up experience. At the same time, parents should also provide a good learning environment for their children, keep in touch with teachers and promote their children's growth.
