1, 2, 3, 5, 8…It’s Fibonacci Day! Here are Some Books to Help Celebrate.

Have you heard of the Fibonacci Sequence? It’s a number sequence that is based on adding the number that appears before it to get the next number in the sequence. 1, 2, 3, 5, 8, 13, 21…You probably already knew that. Did you know that there are  numerous examples of this sequence in nature? Today is Fibonacci Day and here are some kid-friendly books that honor the boy who discovered this sequence: Leonardo Fibonacci

BLOCKHEAD by Joseph D’Agnese

As a young boy in medieval Italy, Leonardo Fibonacci thought about numbers day and night. He was such a daydreamer that people called him a blockhead.

When Leonardo grew up and traveled the world, he was inspired by the numbers used in different countries. Then he realized that many things in nature, from the number of petals on a flower to the spiral of a nautilus shell, seem to follow a certain pattern. 

The boy who was once teased for being a blockhead had discovered what came to be known as the Fibonacci Sequence!
Blockhead is a 2011 Bank Street College — Best Children’s Book of the Year.

Blockhead has been translated into Japanese, Korean, Spanish and Catalan.  

 WILD FIBONACCI: Nature’s Secret Code Revealed: by Joy N Hulme illustrated by Carol Schwartz

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.

An ALSC Notable Children’s Book

A wonderful introduction to one of the most beautiful connections between mathematics and the natural world–the Fibonacci sequence–through a series of stunning nature photographs.

Discover the biggest mathematical mystery in nature—Fibonacci numbers! Named after a famous mathematician, the number pattern is simple and starts with: 1, 1, 2, 3, 5, 8, 13. Each number in the sequence comes from adding the two numbers before it. What’s the mystery? The pattern crops up in the most unexpected places. You’ll find it in the disk of a sunflower, the skin of a pineapple, and the spiral of a nautilus shell.

This book brings math alive, celebrates science, and will inspire kids to see nature through new eyes.

You and your kids can also celebrate the day by sorting coins, buttons, cheerios, macaroni, or other small objects into piles using the sequence. How far can you go?
