Final Eight

Task 1 ... Years 4 - 10

Summary

Team competition sports usually have a process for working out season champions that involves top teams playing off in a defined sequence. This task explores the Final Eight system of the Australia Football League (AFL) as an example of how mathematics is applied to design these play-off systems. 		 

Materials

  • Two dice
  • Team cards (pre-cut)
  • Position cards (pre-cut)
  • A3 playing board
    (Note larger size)

Content

  • collecting and organising data
  • mathematical modelling of a real-life situation
  • probability and chance
Final Eight

Iceberg

A task is the tip of a learning iceberg. There is always more to a task than is recorded on the card. 		   

Possible iceberg investigations for this task are:

  • Design and investigate a different final eight structure?
  • Design and investigate a final four or final six structure?
  • Using Final Eight as a guide, investigate the finals structure of your favourite sport.

Whole Class Investigation

Tasks are an invitation for two students to work like a mathematician. Tasks can also be modified to become whole class investigations which model how a mathematician works. 		   

Changing this lesson to a whole class investigation requires multiple copies of the board based on one per group of 8 and two dice per group. Students write their name on a slip of paper. This is placed where they finish on the 'ladder' at the end of the season (first to eighth) and that position is decidedly randomly; perhaps using a shuffled suite of cards Ace to 8 from which the students draw their position. The investigation is focussed on the fairness of this particular finals system and involves data gathering and representation, probability and reasoning skills.

The whole class lesson for this task is detailed in Maths300 Lesson 149, Sporting Finals and includes a reproducible copy of the board. The lesson also extends the investigation with software.
