Have you seen Rory's Story Cubes? You can buy them on Amazon, and I've been hearing lots of good things from teachers who use them for writing centers.
As you can see, they are really inexpensive! With this set, you get nine dice, each with a different picture on each face. You roll the dice, then create a story with the pictures you see.
Teachers that have used these say that students LOVE them, and even reluctant writers choose Story Cubes for their free choice center. I think they'd work well as a library center for all ages!
You will need to model these for your students before you turn them loose. And, if you want students to create a written product, you can use these graphic organizers from Best Practices 4 Teaching's TPT store. It's a 17-page free download!
I'm going to order some Story Cubes from Amazon today and give them a try. I love open-ended activities that allow students to use their imagination. They spend enough time filling in the bubbles, right?
Have you tried Story Cubes in your library? Let us know how it goes!
