This chapter explores the sociocultural processes of creative planning through an examination of the process of children’s collaborative creation of a play. We argue that creative planning processes are grounded in practical considerations of sociocultural activity, in a wedding of imagination and pragmatics. Original, workable ideas evolve from a process that is the synthesis of spontaneous improvisation and organized, directed activity, as individuals participate with others in sociocultural activities. We examine how a collaborative interactional system develops in the process of planning, and how this social organization is essential to the planning process, as a group of young children plan a play. We follow the germs of the children’s ideas as they are offered, critiqued and elaborated by each other, and consider the

role of classroom structure, teacher support, and fairy-tale scripts as cultural aspects of the event.
