Electoral Systems: Preferential VotingActivities & Teaching Strategies
Active learning helps students grasp preferential voting because the process is procedural and iterative, which simulations and hands-on tasks make visible. By physically redistributing votes and tracking changes, students experience how a majority is built step by step, beyond abstract calculations.
Learning Objectives
- 1Explain the step-by-step process of preferential voting, including how preferences are distributed.
- 2Analyze how preferential voting influences the final outcome of an Australian House of Representatives election.
- 3Compare preferential voting with a first-past-the-post system, evaluating the fairness of each.
- 4Identify strategies that political parties employ to maximize their vote count under preferential voting.
- 5Critique the effectiveness of preferential voting in ensuring majority representation.

Whole Class Simulation: Mock Preferential Election
Divide the class into candidate roles with policy platforms. Each student votes by ranking preferences on ballots. Tally first preferences, eliminate lowest, redistribute, and continue until a winner emerges, discussing results.
Prepare & details
Explain the mechanics of preferential voting in Australian federal elections.
Facilitation Tip: During the Mock Preferential Election, appoint a student timekeeper to announce each redistribution round and a recorder to update the board totals aloud so the class can follow along.
Setup: Flexible space for group stations
Materials: Role cards with goals/resources, Game currency or tokens, Round tracker
Small Groups: Real Election Analysis
Provide results from a recent federal election. Groups map preference flows using flowcharts. They identify key deals and predict alternate outcomes if preferences shifted.
Prepare & details
Analyze how preferential voting impacts election outcomes and party strategies.
Facilitation Tip: For the Real Election Analysis, provide printed sample ballots from a past election and have groups annotate preference flows with colored pencils to visualize vote movement.
Setup: Flexible space for group stations
Materials: Role cards with goals/resources, Game currency or tokens, Round tracker
Pairs: System Comparison Cards
Pairs sort cards comparing preferential voting to first-past-the-post and proportional representation on criteria like fairness and outcomes. They debate and present one strength each.
Prepare & details
Compare preferential voting with other electoral systems, assessing its fairness.
Facilitation Tip: In System Comparison Cards, supply blank cards and prompt pairs to include a concrete example from their simulation to ground their comparison in real data.
Setup: Flexible space for group stations
Materials: Role cards with goals/resources, Game currency or tokens, Round tracker
Individual: Strategy Ballot Design
Students design a ballot for a fictional electorate, then vote and reflect on how party positioning affects preferences.
Prepare & details
Explain the mechanics of preferential voting in Australian federal elections.
Facilitation Tip: For Strategy Ballot Design, give students three sample voter profiles and ask them to create a ballot that could change the outcome based on those profiles.
Setup: Flexible space for group stations
Materials: Role cards with goals/resources, Game currency or tokens, Round tracker
Teaching This Topic
Teach this topic by starting with a concrete, local example familiar to students, such as a class election for a school representative. Use the board to model each redistribution round slowly, narrating why votes move and how totals shift. Avoid rushing to the final result; instead, pause after each elimination to ask students to predict the next step. Research in civic education shows that repeated, scaffolded practice with immediate feedback deepens understanding of complex systems like preferential voting.
What to Expect
Students will explain how votes are redistributed in rounds and why a candidate needs more than 50% to win. They will compare this to other systems and design ballots that demonstrate strategic voting or preference flows. Clear articulation of the process and its outcomes shows successful learning.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring the Mock Preferential Election, watch for students assuming the candidate with the most first preferences will always win.
What to Teach Instead
Interrupt the simulation after the first round to ask groups to predict who might overtake the leader once lower candidates are eliminated, then continue to see if their prediction holds.
Common MisconceptionDuring the preference flow activities in Real Election Analysis, listen for groups stating that preferences only matter after the first choice is eliminated.
What to Teach Instead
Ask groups to color-code ballots by first, second, and third preferences and watch how total vote shares shift after each round, even when the leader initially holds first preferences.
Common MisconceptionDuring Strategy Ballot Design, notice students leaving blanks or writing only one preference.
What to Teach Instead
Circulate with a checklist and remind students that in single-member electorates they must number every box to avoid informal votes, then have them correct their ballots before proceeding.
Assessment Ideas
After the Mock Preferential Election, provide a simplified ballot with four candidates and sample first preferences. Ask students to identify the candidate to eliminate first, show how votes redistribute, and state who wins if the next candidate reaches an absolute majority.
After Real Election Analysis, pose the question: 'Does preferential voting ensure the elected representative truly reflects the majority will of the voters in their electorate?' Facilitate a class discussion where students use evidence from their annotated ballots and preference flow charts to support their arguments.
During the System Comparison Cards activity, present students with a scenario: 'Candidate A has 40%, Candidate B has 35%, Candidate C has 25%. Candidate C is eliminated. Ask students to show how Candidate C's votes distribute and determine if either A or B now has an absolute majority before they finalize their comparison cards.
Extensions & Scaffolding
- Challenge students to design a preferential ballot that would elect a candidate with only 30% first preferences by carefully crafting the profile of second and third preferences.
- Scaffolding: Provide a partially filled ballot with only two preferences numbered and ask students to complete it to demonstrate understanding of the process.
- Deeper exploration: Invite students to research a country that uses a mixed-member proportional system and compare how preferences function there versus in Australia.
Key Vocabulary
| Preferential Voting | An electoral system where voters number candidates in order of preference. If no candidate wins an absolute majority, the candidate with the fewest votes is eliminated, and their votes are redistributed according to the next preference. |
| Absolute Majority | More than 50% of the total votes cast. In preferential voting, a candidate must achieve this to be declared elected without further redistribution of votes. |
| Preference Distribution | The process of reallocating votes from eliminated candidates to the remaining candidates based on the voters' stated preferences. |
| Informal Vote | A ballot paper that has not been marked according to the rules, for example, by not numbering all preferences or by numbering them incorrectly. These votes are not counted. |
| Minor Party | A political party that is not one of the two major parties. In preferential voting, minor parties can influence election outcomes through their preferences. |
