I'm going to ask the obvious question here-- what is the intended/stated PURPOSE of this work?
Fair enough.
DS goes to a play-based camp all day, and a couple days a week has other sports activities after camp. His behaviors deteriorates tremendously after too much free plays. That's my main reason for doing school work during the summer.
What bothers me is that he is indeed interested in the materials but argues and fights about doing it.
I will try giving him more controls about when and what to do.
