Have you heard of Tumblebooks? Somehow I've stumbled across this name in a couple places, but I don't know exactly what it is, how it works, or if it makes pizzas. I'm pretty sure not the latter, but hey, a girl can hope.
Since it's summer and I'm on semi-vacation, I'm too lazy to investigate it thoroughly. So I turn to you. Do you know what this resource is or how one would use it in a classroom?
