As I was going through Twitter, I came across a cool site called Storybots. I have heard about it in the past, but never really had the time to explore it. Storybots is an easy to use websites for teachers and parents to use with their elementary aged students. It gives you an opportunity to make your own videos starring "you" and the Storybots. Simply upload a picture of yourself and provide a name and a parent / teacher's email address and you are off and running. This would be a great tool for students to use to summarize a book that they read.
If you are not so interested in creating your own videos because your kids aren't old enough or you don't have enough computers, there are always the other resources on the site. There is an ABC Video series that teaches students about each letter of the alphabet. There is a Behavior Game that kids can play to learn proper behaviors and have better manners. If you are an elementary teacher, you may even want to check out the free Activity Sheets for students to use to color and learn at the same time. Finally, there is a section where you can create your own book!
After checking it out with my 3 year old son, he highly recommends it! Check out this video he liked on the letter "A":
