解説:
日本で一番使われている小学校算数教科書2年Aの最新英訳版。

三つの特色は

1.考えることがますます楽しくなる。思考力,判断力,表現力等がさらに高まる。
2.学んだことをいろいろ生かすことができる。生きて働く知識・技能が確実に身に付く。
3.これからもどんどん学び続けたくなる。学びに向かう力が継続して育つ。

豊かな学びが未来を拓く教科書です。
子どもたちは、「知りたい(知識)」「できるようになりたい(技能)」という思いで教科書を見るでしょう。
でも、それだけではなく「どう考えたらいいか(思考力・判断力)」「どのように自分の考えを表したらいいか(表現力)」も教科書から読み取ってほしいのです。
なぜなら子どもたちの未来は予測困難な社会だといわれています。
そういう社会で自分らしく生きるためには、自分で考え表現し伝え、よりよいものに高めるという態度、すなわち「知的に自立する」ことが必要です。
この教科書は、算数の学びを通して子どもたちが「知的に自立する」ことをめざして編集しました。

[Introduction]
This is the English version of “New Mathematics for Elementary School 2A”. Thinking becomes more and more interesting for children. Children can make good use of what they learned. Children would be motivated to study further.

[Outline]
This is the latest English version of “New Mathematics for Elementary School 2A” which has been most widely used in Japanese elementary schools (Publisher: Tokyo Shoseki Co., Ltd.). This textbook has following three features. 1. Thinking becomes more and more interesting for children. The capacity for thinking, judgement and expression will be improved. 2. Children can make good use of what they learned. They can acquire working knowledge and skills firmly. 3. Children would be motivated to study further. The power to head for learning would be developed continuously. This textbook is designed so that children could shape their future through fruitful learnings. Children would look at the textbook with desires such as “I want to know (knowledge)” and “I want to be able to do it (skill)”. Not only so, but children are also expected to read from the textbook “How to think (capacity for thinking and judgement)” and “How to express their idea (capacity for expression)”. Because the future of children is said to be an unpredictable society. To live your own life in that kind of society, it is necessary to have the attitude to think by yourself and to express, convey and improve your idea. In short, it is required to become “intellectually independent”. This textbook has been edited so that children could become “intellectually independent” through the learning of mathematics.
