Abstract
In recent years, educators have been calling for an increased focus on complex systems across the school years. One approach to achieving this is through modelling, where
children think mathematically about relevant relationships, patterns, and regularities in dealing with authentic problems. This paper reports on the different mathematical models created by three classes of fourth-grade children (9-year-olds) in working a problem that addressed the complex system of team sports. Consideration is given to the problem elements and interactions the children explored, together with the ways in which they operated on and transformed the given data.
