You don’t need to know a thing about the technical details of creating animations, nor do you need to be at all artistic, to make some pretty amazing animated cartoons. Check out these two free animation sites: Xtranormal.com and GoAnimate.com
You can also find some free or inexpensive animation apps for the iPad, iPhone, and other smart phones. Many of these apps include children among their target market, which means that they’re pretty easy to use, although of course you’ll still need to read the instructions.
You can see sample student animations under the Animations category.
