This book is about the caterpillar eating more and more food in order to become a beautiful butterfly. I would use this in my classroom by reading the book and talking about personal growth. I think we could do an activity that would involve them talking about what they want to be when they grow up and what they can do to get their. We might can even have a show and tell career day. I think this is for children in 1st grade and higher. The Lexile Level is AD460L.
