具體描述

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."

看動畫是一種奬勵，每天時間控製在20分鍾，主要是為瞭保護眼睛。如果孩子非常積極地爭取，通過努力最多可以獲得兩次機會，也就是40分鍾。

廣義的書評包括讀後感。讀後感偏重寫自己的主觀感受。讀後感要注意三點：第一，寫讀後感必須有一個明確的中心論點（或中心思想），不能雜亂無章，文意散漫。第二，這個中心論點（或中心思想）必須是從所讀的材料中提煉、概括齣來的，與所讀的材料有著必然的、內在的聯係。第三，寫讀後感必須是寫自己的所讀、所思、所感、所悟。可以寫一點，也可以寫幾點，不求麵麵俱到，但一定要寫自己獨特的認識和理解。從文體上看，讀後感或立論，或駁論，或闡述議論，都與議論文相似，通常把它歸入議論文的範疇，作為議論文的一種。
