具体描述

内容简介

A funny, entertaining introduction to Ben Franklin and his many inventions, including the story of how he created the "magic square." A magic square is a box of nine numbers arranged so that any line of three numbers adds up to the same number, including on the diagonal! Teachers and kids will love finding out about this popular teaching tool that is still used in elementary schools today!

精彩书评

"In this lively offering from the Step into Reading + Math series, young readers will learn about both Benjamin Franklin and magic squares--square grids of numerals in which all the numbers in any vertical, horizontal, or diagonal row adds up to the same sum. The text introduces Franklin as a smart, curious kid whose ideas led him to "inventing cool things"; as a witty, intelligent man whose ideas were the seeds of America's first library, fire station, and hospital; and as a "super busy guy" who amused himself during meetings of the Pennsylvania Colonial Assembly by creating magic squares. An appended section offers step-by-step directions for those who want to construct their own versions of the mathematical puzzle. The engaging, informal style of the writing and the colorful, cartoonlike illustrations make this a playful but solid choice for introducing young readers to Franklin and to magic squares."

古人云：“书中自有黄金屋，书中自有颜如玉。”可见，古人对读书的情有独钟。其实，对于任何人而言，读书最大的好处在于：它让求知的人从中获知，让无知的人变得有知。读史蒂芬?霍金的《时间简史》和《果壳中的宇宙》，畅游在粒子、生命和星体的处境中，感受智慧的光泽，犹如攀登高山一样，瞬间眼前呈现出仿佛九叠画屏般的开阔视野。于是，便像李白在诗中所写到的“庐山秀出南斗旁，屏风九叠云锦张，影落明湖青黛光”。
