The aim of this research is to examine the effect of 8-week traditional children's games on the decision-making skills of primary school students. The research group consists of 40 students studying at a public school affiliated to the Ministry of National Education in Sivas Ulaş district in the 2021-2022 academic year. Among the traditional children's games determined by the Traditional Children's Games Federation; hopscotch, dodgeball, handkerchief snatch and tombik games were played. "Personal Information Form" was used to collect data, and "Decision-making skill scale for primary school students" developed by Sever and Ersoy (2019) was used to measure students' decision-making skills. An 8-week game program was applied to the experimental group for 5 hours per week. In the analysis of the data, arithmetic mean, frequency, standard deviation and correlation descriptive analyzes were made by using the SPPS program. Since the number of students in the experimental groups was less than 30, the Wilcoxon test, which is one of the non-parametric tests, and the comparison of the decision-making skills scores of the students with two variables (gender, age) were analyzed using the Mann Whitney U test. 05 significance level was taken into account. In line with the findings, it was seen that traditional children's games increased the decision-making skills of primary school students, and there was no significant difference in gender and age differences. Based on these findings, the Ministry of National Education can give more place to traditional children's games in physical education and game lessons in primary schools.
