Little, if any, examination of using play-based tools to examine children's opinions in research exists in the current literature. Therefore, this paper is meant to address that gap within the literature and showcase the study about the use of a specific play-based methodological tool in qualitative research. This specific tool called social board was developed for the purpose of a research project, which was carried out as part of my doctoral thesis. The main aim of my doctoral thesis was to identify the socio-cultural value system of Norwegian elementary school children. In this paper, I discuss the basic assumptions of a play-based methodology, which combines pedagogical and psychological approaches. In fact, this methodology has inspired the design of the social board tool. Then, I present how this research tool was developed and used in practice. I also indicate some of the strengths and limitations of the research tool. Ultimately, this study provides empirical evidence supporting the social validity of play-based methodological tools such as the social board.
