The aim of this research is to investigate the effect of teaching the Circle and Circular Region subject in the secondary school 7th grade curriculum by applying Realistic Mathematics Education activities on the development of students' life skills. The sample of this study consists of 46 students studying in the 7th grade of a secondary school in the Aegean Region. In this experimental research, a quasi-experimental design with pretest-posttest control group was used. In the study, it is planned to teach the lessons according to the teaching method in the curriculum in the classroom that constitutes the experimental group, by applying the Realistic Mathematics Education activities on the subject of Circle and Circular Region. As a data collection tool, real life skills scale was applied to both groups as pre-test and post-test. The obtained data were analyzed with non-parametric test techniques. According to the findings obtained as a result of the analysis, it was determined that mathematics teaching with the Realistic Mathematics Education approach was more effective in the development of life skills than the traditional approach and mathematics teaching.
