Abstract
Part of a broader research project on the development of mathematical understanding in
primary classrooms, the research reported in this paper focused on how opportunities to
learn about percentage in two classrooms were shaped by worksheets. The words in the
text, the way that the teachers replicated these orally, a grid used to illustrate the concept of
percentage, the genre of both mathematical and non-mathematical aspects of the
worksheet’s presentation, and the calculation methods presented were all potentially
influential aspects. It is argued that the “knowledge†conveyed by the texts of the
worksheets was distributed over a much wider field than the classrooms involved.
