This article reports a research project, where two pairs of children were recorded in discussion, first in Year One and then five years later in Year Six. A unique opportunity meant that the children engaged in the same task at the beginning and end of their Primary School education. The research analyses the talk on three levels, considering the language that they use, the way that they manage their talk together, and the broader themes that they bring to their discussion. The findings suggest that their language changes subtly over time, with their earlier discussions more imaginative and fluid.
