I tend to agree with you - kids need a lot of active time. The good news about his school is that they have short bursts of learning, matched with equal times of physical activity. So, they have it balanced. The girls aren’t crazy about this (they tend to cluster together and talk), but the boys love it. Plus, there’s a long daily recess and PE multiple times a week.
However, it has little impact on my son. He just wiggles and works really slow and sloppy until it’s break time - disrupting the class every chance he gets. This is frustrating because he knows he isn’t supposed to be disrespectful and he has been punished many many many times for it at home. Didn’t help at all. Or, he will start a worksheet and then look around, not finishing it. At home, I can get a little more work out of him - it’s calm and quiet, but not much. I “homeschooled” him this past summer to see how he’d do before kindergarten. The results were mixed at best. There is something else going on with my kid besides being a 5 year old boy. :)
Is he exceptionally smart? Could be he’s bored. Or perhaps his learning style isn’t a classroom style - some kids just learn better hands on. Or is he the kind of kid who is a super extrovert and just *needs* attention?
It’s good that you’ve got a nice private school that will work with you but if that’s still not helping, well, I don’t envy you... good thing for him he’s got a parent who cares enough to not just give up and look for an easy fix!
