꿀잼이 흐르는 수학교실의 비법! 우리는 가르치는 것이 좋은 사람들입니다. 가르치는 기쁨을 사랑합니다. 그래서 언제나 꿈꿉니다. 호기심으로 반짝이는 아이들의 눈망울, 작은 아르키메데스들이 저마다의 유레카를 외치는 교실의 풍경을. 그리고 그 한가운데서 열정적으로 무언가를 가르치고 있는 자신의 모습을 상상합니다. 하지만 무대 아래 관객으로 남아버린 학생들에게 수학하기는 여전히 즐거운 것일까요? 이 책은 오롯이 학생들의 아이디어가 주인공이 되는 수학교실 속으로 우리를 초대합니다. 이곳에서 학생들은 저마다의 기상천외한 생각으로 덧셈과 뺄셈의 방식을 창조합니다. 서툴렀던 아이디어들은 서로 간의 소통에 의해 더 큰 앎으로 번져갑니다. 친구의 생각을 지렛대 삼아 수학적 개념들은 점차 연결되고 학생들은 모두 자신만의 수학을 구성해 갑니다. 이 책을 읽는 내내 여러분은 도전적인 과제도 이해해보려 안간힘을 쓰는 학생들의 끈기에 놀라고 그들의 새로운 발상에 감탄할 것입니다. 여느 학자들만큼이나 진지한 토론으로 수학적 오류들을 수정해가는 학생들의 열렬한 팬이 되어갈 것입니다. 그리고 마침내 여러분의 마음속엔 ‘모든 아이들은 스스로 생각해내는 기쁨 속에서 성장할 수 있다’는 굳건한 믿음이 자리 잡게 될 것입니다. 전국의 모든 예비교사와 좋은 수업을 고민하는 모든 분들이 이 책을 읽기를 소망합니다. 책의 마지막을 덮을 땐 제가 그랬듯 여러분의 가슴도 뛰고 있을 것입니다. 우리가 늘 꿈꾸던, ‘모든 아이들이 즐거운 수학교실’의 구체적인 모습이 바로 여기 있기 때문입니다.
