Abstract
This paper is the result of a school/university partnership that was formed to enhance teachers'
professional development. The partnership explored pedagogical practices that promoted
students' mathematical thinking and sense making. The links between assessment and
instruction are described using 'accounts of practice' that are grounded in classroom contexts
and provide guiding principles for mathematics educators seeking to make assessment more
student centred and purposeful. The findings contribute to a growing body of empirically based
knowledge related to the nexus between assessment and instruction.
