In this research in qualitative model, it is aimed to examine the secondary school Turkish textbooks prepared within the framework of the Turkish Lesson Curriculum, which was renewed in 2017 and is still in force with various updates, in terms of including traditional children's games. In this context, secondary school Turkish textbooks published by the Ministry of National Education, which have been decided to be taught by the Board of Education since the 2017-2018 academic year, are the study objects of the research. The textbooks mentioned within the scope of the document analysis method were subjected to descriptive analysis separately by three different field experts in terms of including traditional children's games. Since the preferences in determining the contents of traditional children's games are subjective, Miles and Huberman's (2016) reliability formula was used in order to ensure unity among the three researchers and to increase the coding reliability, and the reliability of the research was found to be 0.87 at the end of the calculation. At the end of this process, consensus among researchers was achieved. Based on the findings, it was concluded that the textbooks were insufficient in terms of referring to traditional children's games, the games in the books did not comply with any standards or plans, the traditional games were included in the 5th grade textbooks at most, and very few and sloppy visuals were added. Suggestions for curriculum developers, textbook authors and teachers were presented at the end of the study. It is thought that the data and results obtained from the research will contribute to the researchers working in the fields of folklore and Turkish education in terms of presenting data.
