Picture Window Books came out with a series called "The Other Side of the Story" in 2011. There are 4 new versions of old classics.
Believe Me, Goldilocks Rocks!: The Story of The Three Bears as told by Baby Bear by Nancy Loewen, illustrated by Tatevik Avakyan has Baby Bear, aka Sam, finding Goldilocks and they become friends.
Trust me, Jack's Beanstalk Stinks!: The Story of Jack and the Beanstalk as told by the Giant by Eric Braun, illustrated by Cristian Bernardini finds the Giant quite upset being painted as the bad guy. He claims that humans are nutritious and sneaky.
Honestly, Red Riding Hood was Rotten!: The Story of Red Riding Hood as told by the Wolf by Trisha Speed Shaskan, illustrated by Gerald Guerlais is a delicious tale from the wolf's point of view and he was only trying to find something to eat, he hadn't eaten in weeks!
Seriously, Cinderella is So Annoying!: The Story of Cinderella as told by the Wicked Stepmother by Trisha Speed Shaskan, illustrated by Gerald Guerlais has Cinderella way to chatty and the stepmother not so wicked.
All the stories have cartoon-like pictures that were digitally created. Although there's not a great depth to the stories, the variant comparison is a favorite tool I use to get kids thinking about stories and rewriting and writing their own. The suggested age is right on, I'd use it with grade 1-3, maybe even 4th.
The books have a page titled Think About It in the back with recommendations to read a classic version of the fairytale and compare. They have a short glossary that names the narrative terms of character, narrator, point of view, and version. There are titles for further reading, with a kid safe internet site listed.
