초록

초등 수학 교과서에서 모눈종이의 활용은 수와 연산, 도형, 측정 영역에서 사용하고, 이 중에서 도형 영역에서 가장 많이 사용하고 있다. 이러한 사용에도 불구하고 실제 초등 수학 교과서의 모눈종이를 활용한 수업 과정을 보면 모눈종이 사용에 따른 시행착오의 수정이나 보완이 어려워서 보다 효과적인 방안이 필요해보였다. 이에 본 연구에서는 한국과학창의재단(2017)의 '수학 수업용 교구 표준안'에서 제시한 교구 중에서 모눈종이보다 더 효과적인 모눈종이판 교구의 활용성을 설문 조사 하였다. 조사는 초등 수학 교과서에서 모눈종이를 활용하고 있는 차시별 학습주제 중에서 모눈종이와 모눈종이판에서 어느 것이 더 효과적인지를 교사들에게 조사한 후, 모눈종이판의 활용이 더 효과적인 학습주제의 성취기준을 찾아 분석하고, 영역별로 가장 효과적인 학습 주제의 구체적인 활동 과정을 제시하였다.

The use of grid paper in elementary mathematics textbooks is used in numbers and calculations, figures and measurement areas. Among them, it is used most in the figure area. In spite of this utilization, it is necessary to supplement it because it is difficult to revise or supplement the trial and error that often occurs in the course of the course, as the process of using the textbook paper in the actual class. The use of grid paper in elementary mathematics textbooks is used in numbers and calculations, figures and measurement areas. Among them, it is used most in the figure area. In spite of this utilization, it is necessary to supplement it because it is difficult to revise or supplement the trial and error that often occurs in the course of the course, as the process of using the textbook paper in the actual class. In this study, we tried to find out the usability of grid paper boards which can be used more effectively than the grid paper among the teaching aids presented in the 'Development of teaching aids standards for math class' of Korea Foundation for the Advancement of Science & Creativity(2017). A questionnaire survey was conducted on the use of grid paper and grid paper board for teachers who actually use grid paper in elementary mathematics. As a result, we found out the achievement criteria of grid paper board utilization and investigated the study subject which is effective to use grid paper board. In particular, we have identified specific learning topics that are effective in each area and presented specific activities.
