In a whole-class discussion, students discuss what has been learned and the strategies used.
To help you assess how well students are able to articulate verbally the relationships between variables arising in everyday contexts.
To help you assess how well students are able to translate between everyday situations and sketch graphs of relationships between variables.

To help you assess how well students are able to reflect on the domains of everyday functions and in particular whether they should be discrete or continuous.
