I think it's enough for the first-grade pupils to learn from the school teacher. There is no need to add extra burden to students. It is difficult to learn and think about content, and it is not easy for children to learn. This is not conducive to children's enthusiasm for learning, but also to the healthy development of students. This is my personal opinion. First-grade pupils have just entered school, so it is good for them to study easily and happily and build up their interest in learning.
