The Graphs and Networks program is an essential part of the Year 12 Mathematics General course as outlined in the Australian curriculum. We show students how to use graphs and networks to represent and analyse everyday situations. They conduct analysis on information contained in graphs and networks and communicate conclusions using appropriate mathematical language, notation and diagrams.
