Your poor daughter! Can you consider homeschooling her for awhile? Mine were at Montessori until the end of grade 2 and SK, respectively. They were often bored, even in that environment. What pushed me to homeschool was watching my older stepson, also bright-to-gifted (but untested) slip through the cracks in school to the point where he stopped attending and earned about 1 credit per semester in highschool (we didn't have custody and weren't informed of these things as they happened). He just tuned out entirely and wasn't prepared to "play the game".
Not trying to scare you, but if her innate love of learning is squashed already in K, and she's running into conflicts with the system already, you may end up with an even bigger problem on your hands some day.
It's going to be at least 3 years before they start teaching the math she already knows, and by then she'll be further ahead still. It sounds like your present school is not very clued-in to gifted issues.
Wish there was an easy answer...
