My DS just turned 6 also and we are in the same boat.
He skipped kinder so is in 1st but is also doing at least 3rd grade math and phonics reading etc. I dk what to do.
I am worried about the emotional factor skipping. I gotta say my DS is not ahead emotionally. I am leaning towards the gifted 1st in public in Sept 2009. This will be a repeat of 1st though. When they see the work he is doing there is no way they can give him 1st grade work. I am hoping anyway. I will not make him do 1+2 and read cat in the hat.
