I teach in a county where kids are allowed to have cell phones. They aren't suppossed to turn them on, but they do. I want to scramble the signal at least in my room. Any cheap way to do this?
I know a HAM radio would work, but is there anything cheaper?

Nope... no way of doing that :( Its a part from your cell phone operator and not you... (maybe if you make your room plastered with lots of glass over cement over glass over steel then the network frequency wont be able to enter the room lol)
