I don't think the problem is that she doesn't want to be challenged. The problem is that she wants to play as much as the other kids. She probably finds it unfair that the rest of the class gets to do what she considers playing and she has to do something else. Would it be possible to ask the 1st grade teacher to let her to participate in the centers and give her 2nd grade math only if the rest of the class does a seat work?

As for the grade skip she would probably be more than fine.
