This is the first tool that I actually had some experience with and didn't have to spend 3 hours on! I don't have an iphone or ipad, but my son has an itouch. I have played around with it quite a few times. Also, my phone is a Droid which also has a wide variety of apps that are educational and similar to the apps found on an itouch.

I have listed some apps below that I feel could be useful in the classroom. There are apps from NASA that could be used in science, Art apps that could be used to promote creativity, apps about the Constitution and Declaration of Independence that could be used in social studies, and a math app that deals with solving puzzles.

I think kids would enjoy using these in the classroom. A lot of kids already have experience with apps, but most of them are probably not even aware that there are educational apps available to them.

I found some apps that looked good, but were not necessarily free. There were apps that teach letters, sounds, and beginning reading and writing. It has been my experience that even the apps that are not free usually don't cost more than a couple of dollars.

Listed below are the free apps I found interesting....
