Swirl by Swirl: Spirals in Nature, by Joyce Sidman, illustrated by Beth Krommes, Houghton Mifflin Books for Children, 2011.
A nice find at the library! I love picture books that bring forth mathematics concepts to children in beautiful ways. This is a very nice picture book for young readers that explore the concept of spirals present in the natural world. Wonderfully illustrated, and written in simple, poetic language. On the two last pages the author offers more information on the subject and explains the basic mathematics behind each one. This will be very useful for an elementary school child who will be attracted by the book and want to know a little more.
