Description How Many Hairs On a Grizzly Bear? And Other Big Questions about Numbers introduces children to a world of fascinating information about the infinite world of numbers. Through vibrant, playful illustrations and fact-packed but witty text, the book explores the answers to questions such as "How many leaves on an oak tree?", "How many stars in the Milky Way?", and "How many stones in the Great Pyramid of Giza?", and covers a wide range of subjects, including animals, the human body, engineering, and Earth and space. Written by Tracy Turner, the book begins with small, easily observable numbers before building up to truly gigantic ones, like a nonillion, a tredecillion, a googol, and even ones too huge for names! Includes an introduction by Kjartan Poskitt, author of the bestselling Murderous Math series.
