Not a school, but some activity ideas. I found a swing/hamock that attaches to a door frame at a Disablity conference once, it was wonderful, my kids wore it out. If you have an unfinsined basement, you can use regular swings and hamocks on the big bike hangers screwed into the joysts. A mini trampoline is another good large motor device that we found helpful.
Good luck,
M.
