This lesson unit is intended to help you assess how well students are able to:

  • Analyse a realistic situation mathematically.
  • Construct sight lines to decide which areas of a room are visible or hidden from a camera.
  • Find and compare areas of triangles and quadrilaterals.
  • Calculate and compare percentages and/or fractions of areas.


This tool describes ways in which digital technology can be used to support formative assessment. The original materials (pen-and-paper) were designed by the Mathematics Assessment Project and can be found under the link above.
