So far, I haven\'t bought a single app for the iPad cart...not because I don\'t want to, but because we haven\'t set it up to buy multiple apps and put on all the iPads. That being said, the kids seems fairly happy with the free versions of the things we have done and I have been able to teach across the curriculum with the free apps. The downside is the amount of time it takes to find things that will work.
I\'ve recently placed a link on the iPads that goes to my google site so the kids can go straight to websites on some days.
Free apps work so far!
