Olympiad Mathematics is a way to train top students in mathematics. Students who study Olympic Mathematics must have a good mathematical foundation and interest in learning Olympic Mathematics, both of which are indispensable. Nowadays, many people have a misunderstanding about Olympic Mathematics. In fact, the role of Olympic Mathematics for students is not as good as basic learning. For the vast majority of students, it is necessary to lay a good foundation in school. Olympic mathematics is a special kind of education. In the teaching process, it is also found that quite a few children learn well after establishing their interests and make rapid progress in various subjects. It shows that once you get started, Olympic Mathematics is still helpful to improve other courses. Generally speaking, it is most appropriate to start learning Olympic Mathematics in the fourth grade. Because at this time, the child is entering a period of thinking mode transformation. At this time, it is best to train their thinking mode and problem-solving ideas. However, the fourth-grade Olympic math class is not difficult. If parents can help, the effect of parents' self-help is the best, because you know your children best. This is called teaching students in accordance with their aptitude. Another problem of parents' guidance is that many parents can't master the problem-solving skills and can't tell the problem-solving ideas; I know it in my heart, but the children don't understand or find it boring. If this happens, it's best for parents not to talk about the specific content in a hurry, but to cultivate their children's interest and adapt them to your teaching methods. Therefore, parents should decide whether to take the Olympic math class according to their children's specific conditions, and should not blindly follow the trend or strongly oppose it.
