There are so many great books out there for teaching Point of View and perspective. When I talk to my students about point of view, I always read to them numerous picture books to show them that a creative story can come from changing around the point of view of a familiar story, or writing a story from an unusual perspective.
I always read to my students, The True Story of the Three Little Pigs by Jon Scieszka. This is a story of the three little pigs from the point of view of the big bad wolf. They love this story!
I then have my students read the original version of Little Red Riding Hood. In groups of four they pick a character (the mom, little red riding hood, grandma or the wolf) out of a hat. They then have the re-write the story from the character’s (that they chose) perspective.
To share, I have break into groups and have all the grandma’s share, all the little red-riding hoods share, together. They enjoy hearing how other people wrote their story form the same character’s point of view.
Other good picture books I use for point of view and perspective:
The Fourth Little Pig by Teresa Celsi
Dear Mrs. LaRue: Letters from Obedience School by Mark Teague
The Great Gracie Chase: Stop That Dog by Cynthia Rylant
The Great Kapok Tree by Lynne Cherry
Two Bad Ants by Chris Van Allsburg
Wolf Who Cried Boy by Bob Hartman.

This is a great book list for POV — thanks!
