The LaRue series by Mark Teague is great for teaching children about point of view. The humorous stories are told in a series of letters from Ike, the dog, to his owner Mrs. LaRue. If the children miss the clues in the text that let us infer that Ike isn't really telling the truth, the picture clues are excellent. The illustrator used both black and white in the divided page format to show us what is true (in color) and what is false (in black and white).
Notice the use of black and white to explain Ike's point of view.
