Each session lasted 50 minutes from 10:30 AM during the large group activity time on Thursday and Friday. The results of this study were as follows: The group game activities using fairy tales lead to statistically significant differences in the autonomous behavior of young children(p< .001). This indicates that the group game activities using fairy tales have positive effects on the autonomous behavior of young children.
