In the book Two Eggs, Please it tells of multiple characters ordering the same two eggs in multiple different ways. I think this book is a wonderful book to read to your class about diversity. After reading the book I would bring in two different eggs and let the students watch as they are cracked. Just as the two eggs looked vastly different on the inside they were all the same. I would use this book in a K-2nd grade classroom to help students understand that just because certain people look different from you it doesn't mean they actually are. Just as the egg was capable of being served in many different ways we are also capable of doing many different things.
