Wow! That school is saving a lot of money :P

I'd follow bread baker's advice above and get them into groups and then smaller groups. By level would be best but that might just be a nightmare to try to assess and utilize. I guess it depends on how many hours this course runs. If it's long, it might be worth it.

One thought is to get 10-12 strong students to help you for extra credit of some sort. If you can work with them for 30 min. once a week before the lessons on what will be taught, how activities will be done, etc. Then you can have them monitor 2-3 groups each to get things going. You're going to need some Captains, General. This is a big regiment.

I teach large groups and the sad part is you're not going to be able to your best for them with those numbers and mixed levels. You'll have to keep everything very simple to start. Simple language, simple goals and once they're used to your style, you can begin to build in complexity.

I hope that helps a little. Good luck!
