This article aims to use the cultural-historical activity theory (CHAT) framework to analyse the participation of an early childhood teacher in children's creative play, in order to enhance and support creativity. The study is grounded on Vygotsky's Zone of Proximal Development, and highlights teacher's play involvement and the arts as a cultural context for creativity development. Data sources such as video recordings, reflective journal and planning documents were used to describe play episodes from a play area titled the 'Toy factory'. These were analysed by assigning each one to specific rules (e.g. technical, conceptual) and then creativity elements (e.g. process, product) were noted. Findings highlight that creative play underpinned by the CHAT framework is a cultural activity in which children and teachers (involvement) participate in the processes of creation and creativity (rules) in the context of the arts (degrees of freedom). Moreover, the teacher takes on the role of the mediator and scaffolds children's creative play, using cultural tools while endorsing creativity elements. This study provides ample ground to propose corresponding activity strategies (Solve, Reflect, Share and Connect) as unfolded through the teacher's actions, handed to children, to support and enhance their creative play experiences thus framing their Zone of Proximal Creative Development.
