The purpose of this study was to analyze the newly developed elementary school (grades 1 through 8) mathematics curriculum by considering 5 th grade students' and classroom teachers' views. The analysis of the curriculum was realized in three dimensions; (1) Classroom management -classroom physical and emotional environments, teacher and student roles, and interactions, (2) Instruction -objectives, planning, implementation, method and techniques, instructional media, and measurement and evaluation, and (3) Strengths (and/or benefits) and weaknesses (and/or limitation). Qualitative case study method was utilized with the participation of three elementary school teachers and their forty-three fifth grade students were invited. The responses gathered from the participants were content analyzed and then the codes were categorized. The findings indicated that several changes have been done and reflected into the classroom implementation and student-centered approaches have been incorporated into the instruction. On the other hand, some difficulties emerge during the implementation due to lack of infrastructure.

The aim of this study is to examine the effects of GeoGebra on third grade primary students' academic achievement in fractions concept. This study was conducted with 40 students in two intact classes in Ankara. One of the classes was randomly selected as an experimental group and other for control group. There were 19 students in the experimental group, while 21 students in control group. The matching-only posttestonly control group quasi-experimental design was employed. As a pretest, student's first term mathematics scores were used. Data were collected with post-test about fractions. The post-test consisted of 22 short ended questions. Thanks to the scores weren't violated the normality, independent t test was employed. The findings of the study showed that there were significant differences in favor of the experimental group. According to findings of this study, it was recommended that GeoGebra supporting teaching methods can be used on teaching fractions in third grade.
