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."

读书能陶冶人的情操，给人知识和智慧。所以，我们应该多读书，读书能够荡涤浮躁的尘埃污秽，过滤出一股沁人心脾的灵新之气，甚至还可以营造出一种超凡脱俗的娴静氛围。读陶渊明的《饮酒》诗，体会“结庐在人境，而无车马喧”那种置身闹市却人静如深潭的境界，感悟作者高深、清高背后所具有的定力和毅力；读世界经典名著《巴黎圣母院》，让我们看到如此丑陋的卡西莫多却能够拥有善良美丽的心灵、淳朴真诚的品质、平静从容的气质和不卑不亢的风度，他的内心在时间的见证下折射出耀人的光彩，使我们在寻觅美的真谛的同时去追求心灵的高尚与纯洁。读王蒙的《宽容的哲学》、林语堂的《生活的艺术》以及古人流传于世的名言警句，这些都能使我们拥有诚实舍弃虚伪，拥有充实舍弃空虚，拥有踏实舍弃浮躁，平静而坦然地度过每一个晨曦每一个黄昏。

看动画是一种奖励，每天时间控制在20分钟，主要是为了保护眼睛。如果孩子非常积极地争取，通过努力最多可以获得两次机会，也就是40分钟。
