Last month, I saw that there was a summer 1 yuan class, so I reported it to my children. After more than a month's class, the children said they liked it very much, because the class was in the form of cartoons, games, animations and answering questions, and the children could understand the knowledge from the superficial to the deep. Needless to say, my children have begun to be interested in mathematics, and I'm not worried about how much my grades will rise temporarily. After all, it is only primary school, and cultivating children's interest in learning is the most important thing.
