It will really improve, at least on some topics.
Level 4, hobbies, shopping, weekend activities
The fifth floor, entertainment, celebrations and festivals.
Level 6, travel, money, learning another language
Still more suitable for some topics in life. But,

Of course, interest is the best teacher. As long as children are interested, they will take the initiative to learn.
At least it is easier than boring grammar. As long as the teacher guides it properly, it is still good.
(Grade 7 or above is not completely suitable for children's exams.
Because many topics are too social and adult, children have no life experience at all.
Therefore, before the sixth and seventh grades, various topics are still helpful for learning English. )
