Number sense is one of the topics studied by mathematics educators and researchers in recent years, and its importance is emphasized. The number of studies on number sense in our country is increasing day by day. The content analysis of these studies is thought to be a guiding guiding for teachers, mathematics educators and researchers and a guide for future studies. Therefore, the purpose of this study is to determine the tendency of number sense studies published in the field of mathematics education published as an article between 2011-2020 in Turkey. With this purpose 50 articles that meeting the specified criteria have been examined. In the analysis of the data, the "Article Review Form" was used and analyzed with content analysis, presented in tables with frequencies and percentages and interpreted in the light of this information. According to the findings of the research, it has been determined that the most of studies for number sense quantitative studies that using descriptive survey method. It was concluded that the target group of the studies was mostly aimed at primary school 5-8 students and the topic was studied with more than 100 samples.
