We are using it as bonus work after MM, but my daughter loves math. I don't think I'd use it as a standalone curriculum unless my kid were really, really flexible and able to jump from one format to another easily.

Is it possible her old "bra" is from Justice? My daughter has a few of their bra-lette things (like a half cami made of microfiber/cotton blend), for modesty under thin shirts not support of any kind, and they run crazy small and shrink. I think she wore a "30" in those when she was a size 8/10. I wouldn't stop driving her. I would talk to her and tell her how much you love her and are hurt by her attitude. You said she has a tough family situation. It's hard to be a young teen even with the best family support. Is she just being a little chilly to you or out and out rude/ugly? I'd probably still give her another (multiple!) chance(s) absent her being abusive to you and try to show her some unconditional love.
