Sam, you do not have to install apps on each individual iPad. There are devices that allow you to sync the applications from one computer to up to 49 iPads simultaneously. There are iPad carts that secure the ipads, smaller ipad cabinets, sync-charge devices that are portable, and USB hubs used for mass syncing. Most of these solutions sync and charge a classroom set of iPads, making your job much easier. We have a few of these devices at our school and it's been such a time saver. I'd recommend checking out www.ipadcart.info if you're interested.
