This book would be great to use with younger grades such as kindergarten and first grade. The Lexile level of this book is AD20L. It features two people who discuss whether or not the animal is a duck or a rabbit. This would be great to open a lesson on differences. While reading the book, students could make predictions about whether the animal is a duck or a rabbit. After the book has been read, students could use an activity sheet to draw the rest of the duck or rabbit in their habitat. The teacher could then talk to students about how many people can see the same thing differently, but that each opinion is still important and valuable.
