In recent years, there has been an increased focus on using art as an approach in the field of social work. This article examines how painting art can become a valuable tool for communication and social participation for children who suffer from environmental challenges at school and in their upbringing environment. The research is in collaboration with Peacepainting, which uses art painting workshops worldwide to work for equality and peace. Within the framework of social work, we explore painting art as a tool for communication and artistic activity as a social-learning process developed through modes of belonging in a community of practice. Through fieldwork consisting of observation of painting processes, the children’s participation in the workshop and individual interviews with children and instructors, the empirical findings show that artwork provided the children opportunities to experience themselves in new ways through visual expression, which increased their self-confidence. The findings show that painting workshops have the potential to be a changemaker in society and an essential tool in social work practice, creating individual learning processes for the participants, establishing a community for inclusion of exposed groups and contributing to changing the processes of established structural institutions, such as schools, welfare services and the local municipality.
