If I'm understanding right he finishes work while at school and then is allowed to read, but doesn't feel that gives him enough of a change of pace to feel restful? Are there limitations on what he's allowed to read? How about comics or books of jokes? Do other quiet book type things like books of crosswords/puzzles/mazes qualify as reading? How about an extra trip to the bathroom once or twice a day just to be able to take a walk?

Hard for any 3rd grader to sit patiently for as long as they are expected to, especially when they are through with their work. Free reading would be a reward for many kids but maybe not for him?
