So I think the teacher must give a reasonable explanation to this problem. If the teacher is wrong, the teacher should admit that if the teacher has his own ideas, he can also talk about them together, so that children can't have wrong ideas, which is not very good for their knowledge growth.
It is also appropriate for teachers to discuss their own ideas. Admittedly, one of the respondents said it better. "Sitting" in the elevator, the movements of people sitting in the elevator are actually static, relative to the elevator, and the elevator itself is moving. However, this seems a bit far-fetched. The math problem in the third grade of primary school looks a bit like talking about words, and the third grade of primary school has not learned a relatively static one. .......
