KIRKUS REVIEW

“You can call me Blockhead, everyone else does.” So Leonardo Fibonacci declares in first-person voice in the opening of this picture-book biography. Who was he? Fascinated with numbers as a child, Leonardo grew from a daydreaming boy in medieval Italy to become one of the greatest European mathematicians of the Middle Ages. He found something to count everywhere, but his father wanted him to be a merchant and took him to North Africa to do his accounts. Leonardo learned fractions from the Egyptians, geometry in Greece and Hindu-Arabic numerals from India. He wrote a book that posed his mystifying, multiplying rabbit question. The lively text includes touches of humor; Emperor Frederick called him “one smart cookie.” O’Brien’s signature illustrations textured with thin lines re-create a medieval setting. The last page lists things to find in the pictures, like a three-leafed clover and spirals, as well as activities that reinforce his concepts. Few people will know this man’s name, but the book will be a boon to math teachers, homeschoolers and others piqued by the title. (Picture book/biography. 6-10)
