Mathematical reasoning consists of creating mathematical estimations, developing and evaluating mathematical arguments. It also includes abilities of presenting mathematical information in various ways (NCTM, 1989) . Besides, the mathematical reasoning abilities of the children who belong to the primary education level are stated by NCTM. The aim of this study is to search the reasoning abilities of 5 th graders which can be considered as one of the vital skills and the numeracy skills. The

The research of this study was conducted in a Middle School located in Giresun, within the first semester of 2015-2016 school year. 28 5 th graders were included in this research. This study is a case study from the qualitative research patterns. In this study four multiple-choice questions were elected from Problem Solving Test developed by Özsoy (2007) and they were used as open ended problems. For these four open ended questions each group was given one-hour lesson in order to solve these questions and it is applied by researchers. The students were expected to explane their solutions, thought and their answers related to the process for each of the questions. The acquired information was analyzed with the "4-Point Rating Scale'" developed by Marzano (2000) and provided validity and reliability. Every problem was evaluated by its own step. This evaluation was conducted by two researchers and the percentage of agreement of each step was calculated. The acquired finds show that students have difficulty in reasoning substeps like " Deciding the accuracy of solution way, Solving nonroutine problems, Developing logical discussion related to the solution, Generalazing, Determining and Adopting the suitable reasoning" Marzano (2000) .
