Abstract
Authentic artefacts (including brochures, menus, bus timetables and photographs) provide opportunities for students to develop skills in knowing when and how to use mathematical knowledge for representing and solving problems in both practical and realistic situations. This paper examines the influence artefacts can have on Grade 5 children?s capacity to make sense of scenarios by applying personal knowledge and experiences to the problem context. In this investigation the children routinely modified the problem when they felt that the context was problematic or not realistic. Moreover, the participants revised or extended the problem in ways that made the task considerably more sophisticated and more closely aligned to their perception of authenticity.
