Area and perimeter video
This video demonstrates area and perimeter so students have a common understanding of both concepts; this will help to answer the questions: What is area? What is perimeter? Simple problems are presented to engage the audience to think and model ways to create an area shape with different dimensions. The representation will show how the number of squares remains the same as the dimensions change. We can also show how area changes as dimensions change. As we go through examples highlight the perimeter. A table of results can show the different dimensions and begin to connect to area formula. Start with square units and towards the end introduce cm2 and m2.

Scaffolding numeracy in the middle years (multiplicative strategies)
This project investigated the efficacy of a new assessment-guided approach to improving student numeracy outcomes in Years 4 to 8. In particular, it was aimed at identifying and refining a learning and assessment framework for the development of multiplicative thinking at this level, using rich assessment tasks.
