Abstract
The Australian Curriculum: Mathematics calls for the concurrent development of
mathematical skills and mathematical reasoning. What are the big ideas of mathematical
reasoning and is it possible to map their learning trajectories? Using rich assessment tasks
designed for middle-years students of mathematics, this symposium reports on the
preliminary phase of a large national study designed to move beyond the hypothetical and
to provide an evidence-based foundation for learning progressions in mathematical
reasoning in three key areas of the curriculum: Algebraic Reasoning, Geometrical and
Spatial Reasoning, and Statistical Reasoning.
