Hurrell, D., & Day, L. (2015). Developing proportional reasoning. MAV Annual Conference 2015.

It applies to a wide range of contexts across all of the content strands and is considered a critical concept for success in secondary mathematics. It requires an ability to think multiplicatively and relationally, and is often problematic for students.
