Generally speaking, it is most appropriate to start learning olympiad in grade three. The "beginning" mentioned here refers to choosing the specialized course of Olympic Mathematics and starting systematic study. Because at this time, students have a preliminary understanding of mathematics through two years of school study, and have a certain foundation in the understanding and calculation methods of numbers; In addition, 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, at present, social education institutions have begun to offer Olympic mathematics courses in the first and second grades. Looking through the teaching materials and contents carefully is not so much an Olympic math as a simple thinking training. Is such thinking training necessary? The answer is yes. Mathematical thinking training is like doing thinking gymnastics for children. Practicing basic skills from an early age is bound to be helpful for learning Olympic Mathematics in the future. Therefore, the generalized Olympic mathematics learning can actually start from Grade One and Grade Two. Advice to parents: Don't deliberately give children extra math meals in grades one and two. Focus on cultivating children's good math habits, such as the speed of calculation and the correct rate of calculation. But you can play more math games and tell math stories while playing with children. (There are many interesting math games in bookstores or online) However, I think the best way is to organize several children to play together, and parents can take turns to take charge of the organization, which is the most meaningful for children. I don't think we should put too much pressure on the children in grade three to start the formal Olympic Games. Some colleagues think it is best not to go to class, because children in this grade are noisy and not suitable for large class teaching. But I personally think that if parents have done a good job of cultivating their children's interest in mathematics in the first and second grades, at this time, they might as well try it in the big class and let the children go their own way. At this time, the course is not difficult. If the child is really interested in mathematics, he can naturally eliminate the bad factors in the big class and get the answers he wants to know. At this time, parents don't need too much counseling, but they must do a good job of "monitoring". Not only should they be responsible for the children's transportation, but don't ask anything else. At the very least, ask what you learned today and let the children talk about what the teacher said. If you can repeat it all, it will be a great talent. Of course, it's good to be able to speak half, after all, it's just contact. Most children can speak a little, or even not, which is normal. If he can find out similar problems, it means that he has mastered them. There are still some children who can't say or do, and parents should think about where the problem lies. Maybe the teacher's teaching method is not suitable for your child. You can try it yourself. If parents are really busy, they can hire a tutor or sign up for a small class in Olympic Mathematics. Another possibility is that children don't like Olympiad at all. In this case, they either give up (after all, Olympiad is not a compulsory course, nor is it the only way to become a talent) or slowly grind it in another way. As the saying goes, a pestle can be ground into a needle, so what can't be changed? But remember, we are not talking about "hard grinding" here, but "soft grinding". After all, your child is not an iron pillar, he is a small flower, and he is growing. What he needs is sunshine, warmth and water. The good way for parents is sunshine, love is warmth and patience is water. The so-called "soft grinding and hard foam" requires parents to make a lot of efforts and adopt appropriate methods. We will talk about how to "soft grind" the olympiad later. . . Time relationship, so much for the time being, welcome to discuss it together.
