Book Description
1, 1, 2, 3, 5, 8, 13, 21, 34. . . Look carefully. Do you see the pattern? Each number above is the sum of the two numbers before it. Though most of us are unfamiliar with it, this numerical series, called the Fibonacci sequence, is part of a code that can be found everywhere in nature. Count the petals on a flower or the peas in a peapod. The numbers are all part of the Fibonacci sequence. In Wild Fibonacci, readers will discover this mysterious code in a special shape called an equiangular spiral. Why so special? It mysteriously appears in the natural world: a sundial shell curves to fit the spiral. So does a parrot’s beak. . . a hawk’s talon. . . a ram’s horn. . . even our own human teeth! Joy Hulme provides a clear and accessible introduction to the Fibonacci sequence and its presence in the animal world.

A good choice showing children the beauty in Mathematics, 2007-06-08
Wild Fibonacci is a beautifully illustrated book that introduces the reader the Fibonacci sequence and how it appears in nature. For those not familiar with it, the Fibonacci sequence is 1, 1, 2, 3, 5, 8, 13, 21, 34 and so on where the next number is found by adding the two before is (e.g. 2 + 3 = 5, 3 + 5 = 8).
Author Joy Hulme starts with a clear and simple explanation of the concepts, giving the most common examples of where the Fibonacci numbers appear in Nature. Then, with pictures and rhyming verse aimed at the younger audience, she cleverly integrates the formula of the sequence (e.g. 2+3=5) with pictures of animals who have body parts (tusk, tooth, talon, or tail) that curves according to the spiral associated with the sequence.
The book is an excellent choice for parents wanting to instill a love of Mathematics in children because it shows its relevance by linking it to Nature. The rhymes stumble occasionally, but make up for it by being chock full of information for the inquisitive mind. The major shortcoming of the book is that it tries too hard to fit animal's shapes to the curvature of the "equiangular spiral" formed Fibonacci squares (shown in the book). The sea shells shown have a spiral pattern but clearly do not follow the equiangular spiral, an error that will not be lost on a bright young reader.
Altogether, the book is a wonderful addition to a child's library and is highly recommended.
