Ask the homeroom teacher to help you out. My school has two particular pizza and chicken places that we order from so we get good deals. 2 slices should be fine unless you're planning to do it during lunchtime. They'll appreciate it either way.
How big is the class? I've never done pizza with a class larger than six. A bag of mini chocolate bars works a lot better to reward a large class.
