The GT coordinator also ended up doing pullouts with my DS, but that was their idea after I offered to pay for online math.
Which one were you going to pay for? This is something I am happy to put on the table for them.
We tried out EPGY for awhile. It was actually quite boring for my DS, but he was able to do it on his own. (After the GT coordinator saw it in action, she decided it was too dry for a kindergartner and created a compacted curriculum with the school's 2nd grade math and she basically tutored him. That was awesome.) There is a homeschooler's group from this site so the EPGY is not so expensive. But there are other programs that would probably work too - Aleks, e.g. I think even Khan now has an individualized program that is free.
Another thing we did: donated higher level books to the classroom (our DS didn't like to stand out by bringing his own books in, so I just sneakily gave them to the teacher).
I will try to think of other things we did when I have more time...
