공간감각력은 도형영역의 학습과 관련하여 제7차 교육과정 이후 강조되어온 수학적 능력이다. 공간감각력의 신장을 위해 수학 6-가 단계의 교과서에는 쌓기나무단원과 관련하여 쌓인 입체의 위, 앞, 옆에서 본 모양이 주어질 때 쌓인 모양을 알아보는 활동이 포함되어 있다. 본 연구의 목표는 쌓기나무 단원의 전술한 활동을 지도하기 위해 교과서에서 제시한 층별 구성적 접근과 달리 새로운 접근법으로서 부분제거법을 제안하고, 그 방법을 6학년 학생들에게 적용해봄으로써 그 지도 가능성 및 효과를 알아보는 것이다.

The cube-accumulation is a new theme included in the 7th elementary mathematics curriculum for improving children's spatial ability. One activity of the cube-accumulation is to recognize the configuration of accumulated cube given three plane figures in the directions of the above, the front and the side, respectively. The approach to this activity presented in the mathematics textbook is more or less intuitive and constructive, and difficult to some children. So we suggest an alternative, more analytic method, 'elimination method', that is eliminating unnecessary parts from $n{\times}n{\times}n$ whole cubes. This method was adopted to the 32 sixth graders, in special five applicants among them. Their responses and activities were analyzed. We confirm that we can teach the cube-accumulation by the elimination method, and some children prefer this method. 13u1 this method requires more exercises to be executed skillfully.
