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."

累积下来，效果非常好。一个暑假里读了200多本书，开口也流利了很多。会用句子而不是单词说话了，自然而然也带有一些语法结构。

感觉像是旧书，只是品相比较好点的旧书。书的边角都有磨损。但还是接受了，不想退货，麻烦。书的内容不错。

我采用的方法是每天读20分钟绘本，就可以获得20分钟动画奖励。要求朗读而不是默读。能自然拼读过去的不强求，读错一点也没关系，读不出来的要查字典。

广义的书评包括读后感。读后感偏重写自己的主观感受。读后感要注意三点：第一，写读后感必须有一个明确的中心论点（或中心思想），不能杂乱无章，文意散漫。第二，这个中心论点（或中心思想）必须是从所读的材料中提炼、概括出来的，与所读的材料有着必然的、内在的联系。第三，写读后感必须是写自己的所读、所思、所感、所悟。可以写一点，也可以写几点，不求面面俱到，但一定要写自己独特的认识和理解。从文体上看，读后感或立论，或驳论，或阐述议论，都与议论文相似，通常把它归入议论文的范畴，作为议论文的一种。
