Go Figure!: A Totally Cool Book about Numbers

As a homeschooling parent, I have read a lot of math books written for children. Go Figure! is one of the freshest and most fun! The pages are saturated with information, and my one complaint is that it feels a bit visually overwhelming. Don't let the colorful pages fool you, this book is very meaty and will take some time to digest. My son really enjoyed the section on ancient number systems. The chart on pages 24-25 compares Babylonian, Hebrew, Roman, Mayan, Hindu, and others. Readers can also learn about the golden ratio and phi, prime numbers, Pascal's triangle, buckyballs, and much, much more. There are nearly 100 pages of information here, geared toward middle school and up.

This is a truly awesome book, full of fascinating insights, entertaining all the way through and amazingly wide in scope, ranging from school math to jokes, puzzles, games and high-level topics like chaos. Note that the "mistake" mentioned in the first editorial review is not really a mistake but an old joke: How many animals of each sex did Moses take on the Ark? The answer of course is "none - it was Noah who built the Ark!"

I found this book incredibly interesting, and I'm no maths fan - I leafed through it while babysitting for a friend who has a son of 9, then I bought the book for myself! It is so well written and extremely funny in parts. I would recommend this book to anyone of any age. I guarantee you will learn something new.

Without math, the pyramids would never have been built. ~ Johnny Ball Go Figure! gives children the opportunity to unlock the magic of numbers through brainteasers, mind-reading games and magic tricks. This book also contains some of the puzzles that have stumped the world's smartest mathematicians. The author, Johnny Ball introduces concepts to make math more fun and very easy to understand. Part of what makes this book quite enjoyable is the full-color pages filled with diagrams, pictures and explanations. The concepts are divided into four main chapters: Where do Numbers come from? Magic Numbers Shaping Up The World of Math Children will learn about Roman numerals, infinity, secret codes, World News, how counting began, shapes, chaos and logic. Johnny Ball also answers the following questions: Did Cavemen Count? How many molecules are in one glass of water? What do the symbols on a Babylonian clay token mean? How did the Mayans count? How do insects use prime timing to survive? How did numbers evolve? See Indian numbers go from 10 symbols to what they are today. One was originally a horizontal line. Three, three horizontal lines. Which really helps to explain why three looks the way it does today. Really fascinating stuff even for adults to read about. As someone who enjoyed writing words upside down on my calculator in school, I thoroughly enjoyed this entertaining book about how math evolved through time. There is even a page comparing 1-100 in Babylonian, Egyptian hieroglyphics, Chinese script, Hindu, Hebrew, Greek, Roman, Mayan and Modern Arabic. The Math quiz is fun and one example: "Find two numbers that multiply together to give 1,000,000 but neither of which contains any zeros." You may need to buy some food for the lessons on page 72. "How can you cut a doughnut into 12 pieces with only 3 straight cuts? How is it possible to push a large doughnut through a cup handle? The book concludes with a list of "Who's Who in the math world and then there are pages of answers to all the questions. One of the most entertaining books on math I've ever read. Definitely will be of interest to children who have any interest in solving problems or want to make learning about math way more fun. ~The Rebecca Review

Go Figure!

Each two-page spread teaches the reader about fascinating numerological concepts in plain and simple terms, from brain-twisting logic puzzles (a TV game show host has you pick from three garage doors, each with a car behind it. After you pick one, he knowingly reveals that one of the doors you didn't pick is empty. Should you switch your choice?) to the amazing shapes of fractals to the fascinating properties of the "golden ratio" phi and much more. Illustrated throughout with full-color diagrams and photographs, Go Figure! takes an adventurous approach to stimulating young minds and exploring mathematical mysteries. Very highly recommended for both elementary school and homeschooling science studies reading lists.
