算数
“My little brother always wants to take precisely the same number of cookies as we do. He insists on dividing them himself, and he does the job very accurately. ” “Oh? Can a two-year-old-boy do arithmetic?” “Well, he makes three rows of cookies, of the same length, and takes one of them.” 　「下の弟はいつも、僕たちとちょうど同じ数のクッキーを食べたがるんだよ。自分で分けるって言い張って、すんごく正確にやるんだ。」「二歳の子が算数ができるの？」「それがさ、クッキーを並べて、おんなじ長さの列を三つ作って、一列分を取るんだ。」
Those who are good at arithmetic can do mental calculation more easily than other students can. So encourage your kids not to use paper and pencils in order to solve simple problems. You should also remember that calculators are sure to be harmful for those who are learning the basis of arithmetic. Calculators give them the correct answers before they understand systems of numbers.　算数ができる子は、他の生徒より暗算が得意です。ですから、単純な問題を解くときにはできる限り鉛筆や紙を使わないようにさせてください。算数の基礎を学んでいる子供たちに、計算器が害を及ぼすことも忘れてはいけません。計算器は数の仕組みを理解する前に正解をあたえてしまうのです。
