Can you get her to wrap it all? When teaching, it's often better to get them to draw the conclusion logically, and then have them explain by working an example with you.
I find that I learn as much or more by teaching than being taught. A good teacher, then, is one who gets the student to teach. Set the stage so the next step is obvious and have them make that leap.
I'm not an expert at it either, but that's what I've noticed from my favorite teachers.
