Parents don't have to worry too much about their children's learning decline, because their attention stability, concentration, persistence and self-control are weak in the second grade. To help children understand the development of their attention and willpower, the learning ability of grade two has developed to some extent, but the learning strategy and learning monitoring ability are relatively low. This is where parents need further help and improvement. Cultivating their independent thinking ability, good study habits and improving learning efficiency will play a great role in their future study.
You can take advantage of your child's opportunity to do homework or study homework, give him some rewards, such as toys, or go out to play to motivate him to work hard, but you can't give him more extravagant items.
I hope it helps you.
