This is not it at all, but it made me think of "Not a Box" which is fantastic and your students may also enjoy it. It's basically a rabbit who has a box to play with and people keep telling him that s/he's playing with a box when in the rabbit's mind, it's really a spaceship, car etc.
Generally, I would just go through here.
Specifically, here are some lists of my favs:
