This article presents an exploration of imagination as a fundamental and often undervalued aspect of human cognition emphasising its crucial role in fostering creativity. Acknowledging the challenges associated with researching imagination and its role in children's learning, the authors explore imagination through the lens of eight core competencies, seen as vital characteristics that children should develop to effectively navigate the personal, cultural, economic, and societal obstacles that they will encounter throughout their lives. Drawing on learning experiences developed by the Institute of Imagination (iOi) for UK primary schools, this study examines how creative thinking, art and design, and making contribute to these competencies. Through observational research conducted in partnership with School 360, a primary/elementary school in London, England, the findings demonstrate how imaginative learning experiences foster creativity, curiosity, communication, and collaboration. This article concludes by discussing the implications of integrating imagination into formal education to better equip children with future-ready skills.
