This study examines how girls and boys in grade three perform gender in their free play in a leisure center. The result of the study shows that both girls and boys choose to relate to gendernorms in their free play in various ways. While some students chose to adopt to gendernorms in thier free play some others chose to take part in the free play by braking the norms. This gender doing was done by students with the help of  the sex-encoded toys offered by the recreation center, the social interaktion, peer relations, language used by students were possible reasons för students gender doing. Thus, the gender and the language as two diffrent sociaal power axes contributed in some case to excluding certain pupils and including others, ehich means the power dominans of gender prevented some students to participate in the free play. Thus, I came to the conclusion that the power dominance of gender is not only an obstacle for students participation in play, but also limits thier possibilitis för action.
