The recoil on an AR is really not that bad, even from standing up. However, I think you should have her sit down and shoot with the rifle resting on something, to avoid the shock of the recoil. I say take everything you have with you. Show her how to use one properly, then let her shoot 50 rounds out of it, then move onto the next, and so forth. I think she will really start to enjoy it after she starts getting good at it! My GF always ask when She can kick my a** at shooting again!
