Book number 12 is The Very Hungry Caterpillar. I LOVE THIS BOOK!!! It has always been a favorite because I love the colors and simple art work. The story is cute as well- but the art work gets me every time. I found this in one of my classrooms that I work in and quickly read it- it's a short simple book that every child really should read! I never would have guessed it was considered a math book!!! I give it ***** (5) Stars
