At present, the child is only in the first grade, so there is no need to choose too many teaching materials. Now the number of senior one students is decreasing, and written assignments are not allowed according to regulations. But to tell the truth, the children in Grade One are too young to know how to study. Even if you listen carefully at school, it is easy to forget if you don't practice, so this requires the guidance of parents to let children practice at home and consolidate what they have learned at school.
These papers you mentioned are similar in nature, and they are all related to class hours, which is convenient for children to consolidate. A few years ago, I used more than 53. Last year, more students used Xueba and Sunshine. Both will do. The basic problems are similar in all aspects. I like to use sunshine students.
I hope my answer can help you adopt it, thank you?
