Use this activity with the book, The One and Only Ivan by Katharine Applegate. Resource links included. Students will compare and contrast nonfiction stories to the story, The One and Only Ivan. Students are then directed to write a postcard to one of the other REAL characters as Ivan, the fictional character in the book. Great for teaching perspective, postcard writing, comparing and contrasting different view points, and comparing and contrasting fiction and nonfiction pieces of literature that are related.
