GuitarGirl,
I play piano and all three of my children have taken piano lessons and they had a beginning teacher who used those books - and those books can be *painfully* slow! I would ask what Ivy suggested - and if your teacher isn't willing, maybe it's time to try to find a new teacher. I'm also not sure how old you are, but if you're still at home with your parents, have you talked to them about this?
Another idea might be to look at books at a music store and see if you can find something that looks like you could play with practice, pick a piece from it, practice it at home until you're fairly good at it, then play it for your teacher to show her you're really serious about feeling you can do "more".
Best wishes,
