I´ve just heard about Mixbook in the Langwitches blog. I imagine you can create wonderful books with students using images from the web or even downloading images from your computer. You can write stories collaboratively, publish them, get the embed code or URL and even have the option of buying a printed copy of the book you have created.
write stories with your students.
write funny stories which students have to continue using their creativity.
have students create dialogues with drawings they have done...
Have a look at this mixbook created by Third Grade students starting poems with " Roses are red, Violets are blue ..."
