内容简介

Professor X and his dog, Y, teach kids how to count exponentially by powers of 10 (1, 10, 100, 1,000, 10,000, etc.), beginning at 1 and working all the way up to a googol (a 1 followed by 100 zeros) and beyond. Children fascinated by large numbers will be amazed how quickly they can count to really BIG numbers, and they’ll also find answers to questions like “What comes after a trillion?” or “What’s the biggest number in the world?” Real-life examples provide plenty of fun facts, such as how much popcorn Americans eat in one year, or how many hairs are on a square inch of a person’s head. Along with the fun comes some powerful learning, as this unique counting book helps kids understand our number system, which is based on multiples of 10.

作者简介

David M. Schwartz is the author of How Much Is a Million? and If You Made a Million.

精彩书评

"This "math journey" progresses exponentially as kids try to keep up with the yield of an out-of-control popcorn machine. Professor X teaches them to count by powers of 10, demonstrating up to a googol (10100) and beyond, as the kids provide a running commentary. While they don't seem much closer to knowing how many kernels of popcorn they have, they do learn a lot of big numbers and entertain each other with such nonsense names as "splendillion" and "elephantillion." Schwartz (Magic of a Million Activity Book) originally used bags of popcorn to demonstrate powers of 10 in school presentations. However, here the hands-on technique of counting the kernels is never explained; the value of the popcorn example is less clear in book form. Sidebars rattle off numerical trivia, adding zeros on every spread (e.g., "One little brown bat can snap up 600 mosquitoes per hour"; "There are 40,000 different characters in Chinese"). These ever-larger numbers inspire Meisel's (The Fixits) lively cartoon illustrations of 105 bees and five billion (or 5 x 109) people in the world. While readers' minds will be reeling with zeroes, they will be buoyed by Schwartz's and Meisel's infinite enthusiasm for their subject."
