Mathematics Standard Stage 6 - Year 12 Standard 2 - Networks MS-N2 Network Concepts


A student:

  • MS2-12-8

    solves problems using networks to model decision-making in practical problems

  • MS2-12-9

    chooses and uses appropriate technology effectively in a range of contexts, and applies critical thinking to recognise appropriate times and methods for such use

  • MS2-12-10

    uses mathematical argument and reasoning to evaluate conclusions, communicating a position clearly to others and justifying a response

  • Subtopic Focus

  • The principal focus of this subtopic is to identify and use network terminology and to solve problems involving networks.
  • Students develop their awareness of the applicability of networks throughout their lives, for example social media networks, and their ability to use associated techniques to optimise practical problems.
  • Content

  • N2.1: Networks
  • Students:
  • recognise circumstances in which networks could be used, eg the cost of connecting various locations on a university campus with computer cables AHCCCTCC
  • given a map, draw a network to represent the map, eg travel times for the stages of a planned journey CCT
  • draw a network diagram to represent information given in a table
  • investigate and solve practical problems, eg the Königsberg Bridge problem or planning a garbage bin collection route
  • N2.2: Shortest paths
  • Students:
  • determine the minimum spanning tree by using Kruskal's or Prim's algorithms or by inspection
  • determine the definition of a tree and a minimum spanning tree for a given network
  • use minimum spanning trees to solve minimal connector problems, eg minimising the length of cable needed to provide power from a single power station to substations in several towns (ACMGM103) ICT
  • find the shortest path from one place to another in a network with no more than 10 vertices AAM CCT
  • identify the shortest path on a network diagram
  • recognise a circumstance in which a shortest path is not necessarily the best path or contained in any minimum spanning tree CCT
