RECENTLY NAMED a Mathical Honor Book!
This fun picture book is a fictionalized story of the real-life mathematician Leonardo of Pisa.
He journeyed to Northern Africa to work in his father’s business more than 800 years ago. He was surprised to learn that the citizens of his new home didn’t use Roman numerals. He traveled the world of the Mediterranean learning all he could about the strange new Hindu-Arabic numerals. Then he wrote books to teach western Europeans how to calculate with them.
The man we now call Fibonacci is largely responsible for converting Europe from I-II-III to 1-2-3. But he’s mostly remembered for a series of numbers known as the Fibonacci Sequence, which describes how many objects thrive and flourish in nature.
