I just fell in love with this thing called Storybird. It is an interactive digital storybook website. Basically, you write your own book online using text and images. You can flip through the final product, share it with friends, and read the Storybirds of others (because they are sometimes really cool).
The website itself is really safe. Storybird emphasizes "niceness" and they will terminate the accounts of people who use the site for political or religious expression, explicit content, or ideas that wouldn't be appropriate brought up around eight-year-olds. Although this is limiting in some ways, this is a really good idea for the classroom.
As a lesson, this assignment can fit all ranges of students. Very simple Storybirds can be created comfortably by struggling students and more advanced students can create Storybirds like the one under the link posted below. This can easily be a lesson that is differentiated, fun, and educational, should you choose to use. I invite you to read the Storybird below. I thought it was profound and poetic, and I'm sure that this can be incorporated in the classroom regularly.
