In this paper, the format of the Korean 2011 & the Japan 2008 elementary school mathematics curriculum are compared especially centered on elements, areas, objectives, and lesson time numbers. Through this comparison, suggestions can be obtained as follows. First, grade-group system which does not meet the actual elementary mathematics education needs to be reconsidered. Second, the area name 'number and operation' needs to be reduced into the area name 'number and calculation'. Third, using the area name 'pattern' needs to be reconsidered. Fourth, using the area name 'probability' needs to be reconsidered. If 'possibility' which some event occurs is seen as ratio, it can be contained area 'quantity relationship'. Fifth, containing the nature of mathematics into the school mathematics objectives needs to be reconsidered. Sixth, it is necessary to enhance the phase of mathematics in elementary education.

Considering precedent studies in which research subjects are mainly confined to secondary school students or higher grade students of elementary schools, we can notice that there has been implicit agreement that instruction of mathematical modeling is quite difficult to lower grade students of elementary schools. Compared to this tendency, this study aims to examine the possibility of instruction of mathematical modeling for all of school ages, and more specifically, the applicability of mathematical modeling tasks to lower graders. To do this, we developed a mathematical modeling task proper to cognitive characteristics of lower graders and applied this task to the second graders. Based on the research results by lesson observation and the teacher's reflection, some didactical suggestions were induced for teaching the lower grade elementary school students mathematical modeling.

수학텍스트의 한 부분인 식은 일상 언어, 시각적 표현, 상징 등의 여러 기호와 함께 학생들에게 다양한 수학을 경험을 제공한다. 그러나 이러한 수학텍스트의 다양성은 수학시험 채점시 4+3인가, 4+3=7인가 혹은 부분점수를 줄 것인가의 이슈로서 변질되어 등장한다. 따라서 본 연구에서는 초등학교에서 다루는 식의 의미, 초등학교 아동에게 지도되는 식의 형태, 초등학교 1학년 아동의 식에 대한 이해, 초등학교 교사들의 식에 대한 이해 형태를 서울시 소재 한 초등학교의 1학년 담임교사 9명과 1학년 1 개 학급에 속한 아동과의 면담 및 설문 조사를 통하여 알아보았다. 아울러 제언에서는 수학텍스트의 한 부분인 식의 실제 교육현장에서 어떻게 반영되고 있는가에 대한 탐색을 통하여 식의 의미를 올바르게 전하기 위한 지도 방법, 교사 인식에 대한 방향을 제시하였다.

거리 수학이 학교 수학에 통합되어 수학 교실에서 지도되고 있는 하나의 예로 어림을 들 수 있다. 학교수학에서 지도되는 지필 알고리즘과는 달리 어림은 대략적인 값을 구하며, 주로 암산으로 수행된다. 그러나 어림은 학생들의 수학 학습과 일상생활에서 많은 유용성을 가지고 있음에도 불구하고 지금까지 수학 교육과정에서는 간과되었으나 최근 들어 강조되고 있는 영역이다. 따라서 본 연구에서는 학교 수학에서 지도되는 어림을 고찰함으로써 거리 수학을 학교 수학에 통합하려는 수학과 교수-학습에 시사점을 제공하는 것을 목적으로 한다. 연구의 목적을 실현하기 위해 거리 수학과 학교 수학을 규명하고, 거리 수학과 학교 수학을 연결하는 다리로서의 어림에 대해서 고찰하였다. 다음으로 초등학교 6학년 학생들을 대상으로 어림 능력 검사를 실시함으로써 초등학교 교육을 통해서 학생들에게 길러지는 어림 능력을 분석하였다.

This paper analyzed contents related to statistics in the 7th elementary mathematics curriculum in conjunction with main changes in the recent revised curriculum. This paper then provided detailed analyses of textbooks and workbooks in terms of main contents, instructional methods of graphs, and comprehension of graphs required to students in order to look closely at how such instructional materials would put the vision of the curriculum into action. It is expected that the issues and suggestions stemming from this analysis are informative in constructing new textbooks and workbooks.

This study examined how elementary teachers perceive and use "problem-posing" as a way to improve students' problem-solving skills in their mathematics classrooms. In the study, a total of 193 teachers in metropolitan areas were surveyed and a subset of 4 teachers were selected for depth-interviews. Results of the study included that teachers did not have a clear understanding of the study included that teachers did not have a clear understanding of the intended meaning of "problem-posing" although many of them have heard about the idea itself. Therefore, "problem-posing" was not fully utilized in their mathematics instructional and assessment. It is suggested that there is a need to develop instructional materials and related professional development of teachers for better instruction of problem-posing in the mathematics classroom.

Even though the variety of expressions are dealt with in Korean elementary mathematics, the systematization of the subject matter of expressions is still insufficient. This is basically due to the failure of revealing clearly the identity of expressions dealt with in elementary mathematics. In this paper, as a groundwork to improve this situation, after the classification of signs as elements constituting expressions, in a position to consider elementary mathematics using transitional signs such as ${\square}$, ${\triangle}$, etc and words or phrases in expressions, expressions were defined and classified based on that classification of signs. It can be presented as the conclusion that the following four judgements which helps to promote the systematization of the subject matter of expressions are possible through this definition and classifications. First, by clarifying the identity of the expressions, any mathematical clauses or sentences can be determined whether those are expressions or not. Second, Forms of expressions can be identified. Third, the subject matter of expressions can be identified systematically. Fourth, the hierarchy of the subject matter of expressions can be identified.

In this paper we review an axiomatic definition of the area of plane figures with area axioms, discuss what the area axioms mean, and analyze the contents about the area of plane figures in elementary school mathematics from the view point of area axioms. So we evaluate which aspects of the concept of area are emphasized or deemphasized in the current elementary school mathematics textbook.

본고에서는 먼저 어림과 근사값의 의미를 고찰한다. 그리고 근사값과 어림수 사이의 관계를 살펴보고 1940년대 초등학교 5학년에서의 어림수의 곱셈과 나눗셈에 대한 지도 방법과 현행 중학교 교육과정에서의 근사값의 곱셈과 나눗셈의 지도 방법을 살펴본다. 이들을 살펴봄으로써 어림과 근사값을 지도하는 의의를 강조하고 어림셈과 근사값 계산에 대한 교수 ${\cdot}$ 학습 자료로서 제시하고자 한다.

In this study, connections between the NURI curriculum for 5 years old children and the contents of teacher's manual books according to it and the contents of elementary 1st grade mathematics curriculum and textbooks was analyzed to find the implications that can help to link the two curricula in the development of kindergarten and elementary school mathematics curriculum. The five following implications could be obtained from the analysis. First, it is necessary to connect the contents of the NURI curriculum for 5 years old children which were completed in that curriculum like 'spatial relation'in geometric figure domain and 'data collection'in probability and statistics domain to the contents of the 1st grade curriculum. Second, in the case of the contents not connected between the NURI curriculum for 5 years old children and the contents of elementary 1st grade mathematics curriculum but connected between the NURI curriculum for 5 years old children and the contents of elementary 2nd ~6th grade mathematics curriculum, it is necessary to re-adjust the hierarchy based on one of the curricula. Third, it is necessary to check whether $\ll$K-teacher's manual book$\gg$ obey the NURI curriculum for 5 years old children or not. Fourth, it is necessary to review the related elements of the NURI curriculum for 5 years old children and elementary 2nd ~6th grade mathematics curriculum in [activity] in $\ll$K-teacher's manual book$\gg$. Fifth, it is necessary to handle the mathematics contents explicitly and systematically in [activity] in $\ll$K-teacher's manual book$\gg$.
