This master thesis deals with childrens free play in preschool. Free play is important for the childrens development. During free-choice time children decide what, where and who they want to play with. There they have the opportunity to choose actions that are interesting for them and that are of an adequate difficulty level, which is not the case during activities such as story-telling for the entire class. Commencing with a chapters about play, free-choice activities and preschool this master thesis aims to find out when and where children in preschool have the opportunity for free playing. After looking into specialist literature, there will be a research about free play in three preschools in Graz. Interviews with the teachers, focus groups with children and event sampling observations in classrooms provide research data. Due to vastly different schedules, a standard proposition for an optimal point in time and space for free play cannot be made. However it could be found out, that there is a lot of time for free-choice activities for children in every of these three preschool classes.
