Description
The Life of Fibonacci is a children’s picture book about the famous mathematician from Pisa, Italy, who discovered the Fibonacci Sequence, which governs how so many objects in nature grow and flourish. The book is set in Italy and the world of the Mediterranean during the Middle Ages.
Blockhead is the kind of book parents and grandparents would buy for children who adore math, history and nature. The book can also be used by teachers who want students to study math concepts such as number patterns, Roman numerals, and place value.
This book helps a child begin to ask such questions as: Why does a starfish have five arms? Why do lilies have three petals? Why is there a spiral buried in the face of a sunflower?
The answers to all these questions are found in the Fibonacci Sequence.
Our book is designed for repeated readings. Children are prompted to search for Fibonacci objects hidden in the illustrations. The book unites what kids learn in school with their wondrous experience of the natural world around them.
Charming and accessible…
— The New York Times Book Review
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.
— Kirkus Reviews, starred review
Math lover or not, readers should succumb to the charms of this highly entertaining biography of medieval mathematician Leonardo Fibonacci.
— Publishers Weekly
D’Agnese’s introduction to medieval Europe’s greatest mathematician offers both a coherent biographical account— spun, with some invented details, from very sketchy historical records— and the clearest explanation to date for younger readers of the numerical sequence that is found throughout nature and still bears his name.
— Booklist
This lighthearted introduction to Fibonacci’s ideas will inspire young math lovers and perhaps point them toward more scholarly explorations.
— School Library Journal
[An] engaging, kid-friendly look at Fibonacci and his eponymous numerical sequence… The book has some clever tongue-in-cheek humor, and D’Agnese does readers a favor by clearly explaining Fibonacci’s breeding rabbits scenario… Throughout the book, O’Brien’s illustrations are textured with swirls and spirals— a whimsical homage to the man who discovered, as he believed, ‘the numbers Mother Nature uses to order the universe.’
— Horn Book
Young listeners should get the gist of Fibonacci’s work, and they can test their skills at identifying numbers in the Fibonacci sequence by looking for examples tucked throughout the artwork.
