Because every school requires students to buy these two exercise books at the beginning of each year, it is quite useful to do more at ordinary times. So parents don't have to worry about which homework will be better, but do it according to the teacher's requirements. If time permits, they can do more, which is always beneficial. You must cooperate with the teacher.

Now teachers in many schools are asking this book to be done. Personally, I think the teacher's recommendation should be good. Anyway, you usually have to do some homework, so just follow the teacher's instructions to buy it. Teachers who don't understand can explain together, which is very good. Parents don't have to worry about their children's homework, as long as they are willing to do it, it will be useful.
