Having been there and done that, I'd suggest that you have her choose a style of photography that she knows she will be involved in. For example, a Mom will be taking photos of her kids, so teaching her shutter speeds, aperture, DOF and such, within that context, should make it easier to learn, retain and practice the lessons. Give her a solid foundation in her chosen style and then later on, apply that knowledge to other styles such as landscapes, formal portraits, wildlife, street, etc. Jumping around from one style to another can be quite confusing and frustrating to someone just starting out.
Also, knowing her learning style beforehand will make things much easier on both of you. I learn best by reading first and then putting it into practice. She may do better listening, and/or watching, or... If she is a reader help her find a few great books or websites, if she is a viewer lead her to the best youtube.com videos. Thankfully photography is something for which there is an abundance of free, or nearly free, learning opportunities on the internet. She'll need something to refer to when you're not around, so pick a few sites for her to rely on.
Is she conversant in English ? Will language be a barrier for her ?
