Thanks, aeh and Cookie. It definitely helps to hear what this might look like in practice. At home he will sometimes get on IXL and just go with it for a while on his own, including with topics he's had little to no instruction in, so he *might* be able to handle this independent approach in school. I'm just not sure he'd stay on task with all the distractions around him. Still, I really like this idea of curriculum compacting because it would address pace of acquisition as well as present level. A one-grade acceleration helps a bit, but I've volunteered in the classroom and the pace...it just kills me, ha ha. At least at this very early level of math, kiddo does not need repetition to grasp concepts like rounding, odd/even, etc. And there is SO MUCH repetition!

Are there any specific modifications we should ask for in other strength areas, like reading and writing?
