Parents spend more time with their children to study!
My baby is also in the second grade, and his math scores are still ok!
I don't have much time to study with him I bought the video courseware on Taobao. Every holiday, I ask him to follow the teacher to learn math and Chinese in advance for the next semester. Relatively speaking, when he enters a new course, he will be relatively relaxed. What the teacher said in class is combined with what he taught himself, so that he can better master what he has learned!
Instead of letting children watch TV and mobile phones, it is better to watch more video courseware, which is also helpful for learning!
I hope mine can help you!
