Mathematics textbooks are substitutive showing real characters of didactic transposition in pseudo-contextualization and pseudo-personalization. This study analyzed statistical graphs in elementary school mathematics textbooks according to the first to the 7th curriculum in Korea. It focused on the didactic principles used in those methods through those view of Didactic Transposition Theory. The features of the elementary school mathematics textbooks in Korea are investigated and described ethnomethodologically according to each curriculum periods in dividing bar graph, line graph, pictograph, graph of ratio, histogram. The teaching sequences and methods of the statistical graphs, order and methods of sub-learning activities, teaming data, matter of the learning activity indicator were summarized. Usually, the teaching sequences, excepting the graphs of ratio, statistical graphs are introduced in the second semester of each grade. The graph of ratio is introduced in the first semester of 6th grade. As a result of analysing sub-Loaming activities, using them increased from the first to the 7th curriculum and its form was fixed constructive and stable at the 4th curriculum textbooks. As a result of analysing the teaming data, the data of the social aspects are used more frequently and the data of the individual preferences trended more gradually. As a result of analysing the matter of the teaming activity indicators, concept-explanation question style were used more frequently. Statement-practice style and consideration style trended gradually. Concluding remarks are: First, the didactic transposition of the elementary school mathematics textbooks developed systematically according to the first to the 7th curriculum; Second, mathematics textbooks gradually introduced the positive learning style of activity and the learners' spontaneousness; Third, more concrete practice activities and reflective activities were variously introduced considering the level and interest of each elementary student.

초등학교 수학 교과서에 나타난 통계 그래프의 지도 방법을 1차에서 7차까지 각 시기별로 ① 지도 방법 및 시기, ② 학습 세분 활동의 제시 순서와 방법, ③ 학습 소재, ④ 학습 활동 지시어의 유형 등의 네 가지 관점에서 분석하였다. 비율그래프를 제외한 나머지 통계 그래프에 관한 내용은 대체로 각 학년의 2학기에서 지도되었다. 비율그래프는 6학년 1학기에서 주로 지도 되었다. 학습활동의 세부화는 1차에서 7차까지 점차 증가하면서 4차부터 구조적이고 안정적인 형태로 정착되었다. 학습 소재는 사회적 특성에 대한 것이 가장 많이 사용되었고, 개인적 선호도에 대한 것이 점차 증가하는 추세이다. 학습 활동 지시어의 유형은 개념 이해 질문형이 많이 제시되었고, 점차 진술 및 조작형과 사고형이 증가하는 추세를 보였다.
