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."

一般录音会延迟动画几天。首先是为了让孩子被吸引，主动要求听录音。其次是补充看动画过程中被忽略的细节。最后是为了加强记忆曲线。

　　多知识结构分级阅读，是一种横向分级阅读。其本质就是在多年龄段分级阅读中，对各类知识的读物进行科学的、合理的配比，给少年儿童读者提供知识结构最好的分级阅读。例如，在21世纪初，为了推动多知识结构阅读，中国少年儿童出版社针对中学生读者推出了由50位世界历史名人所写的50部名著集结而成的《“人之初”名著导读丛书》，选取世界上最优秀的政治类读物，如柏拉图的《理想国》，马克思、恩格斯的《共产党宣言》等；文化类读物，如孔子的《论语》等；文学类读物，如斯托夫人的《汤姆叔叔的小屋》、但丁的《神曲》等；科枝类读物，如爱因斯坦的《相对论》等，精编成中学生能看得懂的导读文本。这套名人名著导读丛书，受到了中学生们的热烈欢迎。

听录音不是奖励也不是鼓励。如果孩子喜欢这部动画，就会自然希望听到录音。
