We've completed two stories and posted them to the class blog. You can read them here. I'm sure we'll pop up a few more over the next week or so.
If I did it again with them I'd probably work a little slower, perhaps a bit more scaffolding before launching them into writing their own stories. I'd also tidy up the planning we used. With that in mind I've created a Google Presentation to use with children the next time I try this out..
