I'm curious to hear how your meeting goes and can't really offer you much advice since we are in the same boat. Our boys are similar in age and we got our unofficial acceleration this year to 1st grade (for over 1/2 the day--due to strict age guidelines my son must remain an official K student for the first 2.5 hours of his day). I know that the first grade work will not be enough in math or reading and I hope our school, where there is no gifted mandates, can live up to their promise to differentiate.
I'm glad your son seems to be adjusting to the full day 1st grade. I think keeping him motivated is probably going to be the biggest challenge without some differentiation.
