內容簡介

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!

精彩書評

"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."

聽錄音不是奬勵也不是鼓勵。如果孩子喜歡這部動畫，就會自然希望聽到錄音。
