This book is one of the most interesting books I have ever come across. The illustrations are very cleverly drawn to where you could see two different things (a duck or a rabbit) depending the way you look at it or the angle you are look at it from. The whole book, the author argues whether or not what he sees is a duck or a rabbit. I would say the intended audience for this book is ANYONE! I enjoyed reading this as a college student. It is thought provoking and shows how diverse everyone's thought are. An activity I would do for this book to show students that not everyone thinks the same would be to give each student a blank piece of paper with just a box drawn in the middle. Each student would then have to show their creativity by extending the box into something more than just a box (maybe a robot, or a piano, or anything else they could think of). The results would be amazing and show students that just because people don't think alike, it does not mean they are wrong.
