I think I make it plenty clear I subscribe to Google and all their tools for education. In my school district we use Google Apps for Education, their mail, documents, and more geared to a school domain. We settled on Android for our tablet environment. We even began looking at Google’s Chromebook devices. So I have no problem whatsoever sharing more Google resources with you here.
It seems they really want to step up their Education offerings, including a new eBook, A New and Open World For Learning (https://docs.google.com/a/freetech4teachers.com/viewer?url=http://www.google.com/edu/pdf/Google_EDU_Report_FULL.pdf). In it you will find lots of data and graphics listing all the various Google resources you can use in your classroom. You can also find a great website (http://www.google.com/edu/teachers/educator-resources.html) where they show how you can use all their resources in the classroom. Good resources from Google!
