I highly recommend that you check out this resource as it is a nice listing of educational apps!  Direct Link: https://sites.google.com/site/learningcontinuity/with-ipod-touches  The official tagline for their site is:

If you use iPod Touches in your classroom and students have access to either an iPod Touch or an iPhone, here are some "Apps" that we have on the AUHSD iPod Touches that can help with continuity of learning. iTunes required to access the links.
