For us, it's more of a problem of focus and of DS7 rebelling against parents. He had some math he didn't finish at school, and I could see from the parts he did at school that he understood it and could do it. But then when he brought it home, he just didn't want to be sitting there with me telling him to stop playing with his pencil, etc., and just do it. And while he's goofing off, he'll write down the wrong answer, even though he just said the correct one out loud. I'm sure this is age-appropriate behavior, and I'll make him correct it, but I view the concentration issue as a long-term project. It's certainly trying to watch him spend 30 minutes doing 10 minutes worth of homework.
