This is a very simple picture book that shows two different perspectives of one thing. One side is arguing that there is a duck and the other side is saying it is a rabbit. The book continues through describing different reasons that the picture is either a duck or a rabbit.
This book introduces the different perspectives that people have. There are several other pictures that could be different things depending on your own perspective. I would show the class different examples and have them debate on what they think it is. Class discussion would be the main part of this activity.
