In my teacher training, when we talked about IEPs the point was brought over and over about dicrepancies between ability and achievement. That is one way people go about including giftedness in the IEPs. Her reading is probably as high as it "should" be, but perhaps in math she needs something else to bring her up to speed. Since her perceptual and verbal are close together, maybe that is a consideration.
Nevertheless, some people have successfully included gifted parts in the IEPs. Maybe you could try at your next meeting. I would advice you to read more on this (maybe Hoagiesgifted has some specific resources on that?) and try to get something. It is more likely to be done if they have specific suggestions.
However, as Dottie says, it is much harder for kids working above grade level.
Good luck!
