And I should add that he's also been complaining that his school doesn't have enough math in it that interests him. "They don't do the things I like to do."
Actually his 1st grade teacher is at least willing to give him harder math worksheets after he finishes his work, and lets him have free time when he's done, which is much better than the forced participation in K level math groups, which were way below his level.
He's disappointed he didn't get to skip 1st grade math, but he needs to suck it up and move on. I don't think he's being fair in his complaints about school, but I don't know how to get his perspective back to a more positive one.
