Oh, the lovely iPad! It sits on my desk during the school day and kids come up and take it to use during recess time. I've even had kids meet me at the door in the morning just to be the first in line to use it. Sharing one iPad with 670 students will prove to be challenging, but I'm glad it's a huge success already.
Currently, the two most popular apps are I Spy Spooky House (the kids kick my behind in this one!) and Issac Newton's Gravity. At this point, no one has used it as a reader, but I think this is because they have such a limited amount of time.
