I agree with Howler that it is hard to tell if you have a problem, but from your description of math class, it seems like she could have been learning more. I think there are probably a lot of free online math resources you could find, of your DD is interested. Maybe others can post there favorites here or you could do a search-- I think this has been discussed before.
For a verbal kid, I would recommend Life of Fred books. My DS9 loves them. They are written in the style of a novel with a funny storyline, and math concepts are addressed throughout. My DS never did the problems (end of chapter or end I book, I think?), but he seemed to absorb the math anyway.
