In this Nuffield investigation students study paper sizes in the A and B international series, exploring relationships within each series and between the series.
The key processes are:
*Representing - identifying the mathematics involved in the task and developing appropriate representations.
*Analysing - working systematically, identifying patterns and beginning to make generalisations.
*Interpreting and evaluating - considering the findings to form convincing arguments.
*Communicating and reflecting - explaining the approach taken and the outcomes achieved at each stage of the work.
