I'm speaking from experience. The kids I've worked with who struggle here protest loudly any attempt to "return to basics" because they have done that every year from 4th to 10th grade without success and by that age see it as infantilizing. As to why any individual struggled in the first place is different for every kid. But scar tissue around the subject builds year after year until it's painful for them to return to the subject.
