It has been suggested that expressive and creative activities have great potential for the development of several areas of human development. Therefore, this study aimed to know students' views on creativity, social relationships, and affectivity after participating in expressive activities (dance, drama, and rhythm) based on a creative approach within Physical Education. Seventy-three children aged 11 participated in these activities, and 19 (58% boys) responded to a semi-structured interview. Results revealed three main themes: 1) greater creativity and transference to other contexts; 2) self-confidence, loss of shame, and greater expression of emotions; 3) closer and new social relationships among peers. Children felt more creative and imaginative after the intervention and tried to transfer their acquired creative skills to other contexts. Regarding affectivity, they gained self-confidence during the sessions and felt less embarrassed to express their emotions. Their social skills also improved: they felt comfortable playing and being creative with their classmates, discovered new skills among their peers, and made new friendships. These findings suggest that expressive and creative activities in Physical Education can contribute positively to cognitive, affective, and social domains.
