필수정보

이 책은 “초등 4학년, 수학의 원리를 잡아라”라는 책을 동화로 각색한 “수학천재의 탄생”의 영어판입니다. 수학동화에 나와 있는 재미있는 수학지식과 스토리를 영어로 동시에 공부할 수 있도록 편성하 였습니다. 이 책은 도형을 본격적으로 공부하기 전에 길이 개념을 명확하게 잡을 수 있게 도와줍니다. 통나무와 실을 사용하여 선분이라는 길이 개념을 명확하게 심어주려고 했습니다. ‘길이’ 개념을 이해하면 수를 분해하고 조작까지 할 수 있는 수의 운행 능력을 기를 수 있습니다. 아이가 몰라서 틀렸던 문제 속에 담긴 개념을 알려주고 교과서에서 어렵게 느낀 부분을 쉽게 이해하게 하여 자연스럽게 학교 교육과 정과 연계할 수 있도록 구성했습니다. 한글판을 번역본으로 사용하여 공부하면, 수학의 원리, 동화의 즐거움, 영어 실력을 한꺼번에 기를 수 있도록 하겠다는 것이 이 책의 목적입니다.
