My daughter gets sick of hearing that math is "hard for girls" -- ugh. Before she moved into the gt classroom, DD10 would ask if she was doing something wrong because math was easy for her. We've had lots discussions about gender stereotypes and that maybe math was hard for the teacher to learn.
In the gt class, I've been hearing for years that DD could be going faster in math but they only accelerate one year. We tried EPGY but DD hated it -- not visual enough for her. Math is easy for her but hasn't excited her. The Investigations curriculum that she had for the past four years was repetitious and dull. This year her school changed curriculum and it has made a huge difference -- I think that it is called Connected Math. DD is excited about math for the first time. She actually comes home and talks passionately about things that she figured out in class that day.
Would they let your DD join the gt class? It might be worth observing and seeing if it truly is more conceptual and better fit. It sounds like she needs to get away from the currently math teacher.
