Check out this fantastic free site where kids can write stories, draw a picture, or make a movie. Kids can collaborate with others on their projects, and provide each other with feedback. It will be so fun to play with the drawing function on the SmartBoard as the kids illustrate their own stories. It is a great way to introduce the read-write web to students. 

If you are concerned about using a social site with your children or students please check out my thoughts (and hopefully the comments of others … someday) about why we need to provide children with opportunities to post to the internet in my entry entitled Using the Read-Write web with Children.
