1. What should parents do for their children at home (such as telling their children some idioms and stories).

Parents should pay attention to their words and deeds while educating their children and set an example for them.

3. Encourage children when their academic performance drops, and reward them appropriately when their academic performance is excellent (such as the little red flower prize extracurricular book as a reward).

4. Educate children scientifically, and try not to beat and scold children, which will do harm to young minds.

I hope these ideas are helpful to you. If you are satisfied, please give a point.
