This book would be good for looking at the perception of situations or for looking at the creative minds of others. After we read the book, I would give them a piece of paper and they will draw a duck or a rabbit and we will vote on which animal we thought it was. Perception in a child's eye is important because they see things that we don't. I would want to foster their creativity and allow them to express themselves in whatever way they want. The reading grade for this book I think is Kindergarten and up. You can use this in any grade to show differences and perception. The Lexile Level is AD20L.
