Abstract
This paper engages current thinking about the links between students' early experience with number properties and their future understandings of algebra. It reports on a study of students' understandings and explanations of commutativity. Central to the analysis are both the forms of representation students draw upon and the language they employ to make their understandings explicit. The investigation reveals that despite the rhetoric of educators and the intention of curriculum developers, student learning continues to remain at the procedural level, constraining rather than enabling algebraic reasoning.
