My son is in a self-contained gifted program at our public school for 4th grade. They started with the 5th grade math book and he was placed into the 6th grade vocab book. We got his report card- all As! Reading, vocab, math, etc.
He is hearing impaired and the only hearing impaired child in the gifted program. He's the only kid in his class of 35 with an IEP.
They are working on AMC math problems in class for fun- they don't compete this year. He and only one other boy got 4 out of 5 right! Apparently nobody got 5 right.
