Breaking News: In April 2015 Blockhead was named a Mathical Honor Book.
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. Be sure to check for those editions of this title, if appropriate for your classroom!
