Sounds like the first set of lessons are sets, takedowns, mark roundings anyway. You can get the foredeck and middle up to speed with both the runners tight on a reefed main safely, and then progress to doing it full rig. Crawl, walk, run.
A vote for the idea of just reefing the main...which you will only need to do if it's blowing hard enough that screw ups pose a risk to the mast. If it's blowing hard you don't want to be out there trying to teach the basics anyway. Besides, they will learn to put in and shake out reefs.
