The purpose of this study is to determine first grade pre-service elementary school mathematics teachers’ misconceptions about the domain and range sets for the functions. This study realizing in 2011-2012 academic year is conducted to 57 first grade students who were enrolled in the department of elementary school mathematics education. In this study, descriptive method is used. The data were gathered from misconception test and semi-structured interviews which were prepared by the researcher. According to the analysis of the data gathered, students’ misconceptions about identifying domain and range sets for the functions were divided into two categories as algebraic and geometrical. The most noticeable misconception about identifying domain and range sets for the functions with respect to algebraic category is overgeneralization. Further, geometrically students showed domain and range sets as area above or under the graphic.
