You could use phase 1 of http://www.t-nation.com/training/teaching-a-kid-to-lift
to get her into strength training and...http://www.t-nation.com/training/defranco-agile-8
to increase mobility before each exercise session. ROM will come with doing the exercises with proper form and depth.
You can superset squats/pull-ups (with bands to assist) and box squats/pushups/lunges as a phase 2 instead of the other stuff on the first link.
Goal is to set a PR each training session. For instance, if she did 4 regular push-ups and 11 kneeling push-ups one day in phase 1, then the next exercise session, push her to do 5 or more regular push-ups and finish off the set with kneeling push-ups. Phase 1 shouldn't take that long. It would mainly be used to get her into the mindset of exercise and familiarity with some of the forms. Phase 2 will help her conditioning with the continuous supersets and help more with her form.
Phase 3 would be to put a bar on her back and squat. Possibly put her on a Starting Strength program.
Finish each exercise session off with some abs and conditioning (sprints, prowler, farmers walks, medicine ball, etc.). Prescribe walking and the above mobility exercises on her off days at home.
