Twelve club members have ranked three activities. One counting rule selects A; another selects B. Nobody changes a preference. How can both counts follow their instructions? This Class 9 decision lab makes the puzzle visible: pupils handle the same ballots twice, explain the difference and decide what they want a group rule to achieve.
Class 9 · 40 minutes · groups of three. Prepare the preference table, twelve numbered paper slips, two rule cards and a tally sheet. The outcome is two checked counts and a reasoned rule choice. These are invented club rules for comparing decisions; they do not describe the conduct of Indian public elections.
Keep the preferences fixed
Use the first five minutes to introduce a fictional club choosing one afternoon activity: A, a build-and-make fair; B, a reading café; C, a games afternoon. All three are available. Each member ranks every option once. “A, then B, then C” means A is preferred to B, and B to C; the positions are not points to add.
| Ballot numbers | Number of members | First preference | Second | Third |
|---|---|---|---|---|
| 01–04 | 4 | A | B | C |
| 05 | 1 | A | C | B |
| 06–09 | 4 | B | A | C |
| 10–12 | 3 | C | B | A |
Groups copy the rankings onto the numbered slips or work directly from the table. Assign reader, counter and checker roles. Before counting, the checker confirms there are twelve members, no missing ballot numbers and exactly one appearance of A, B and C on each slip. The data are supplied; pupils need not reveal their own preferences or vote for a real candidate.
Rule 1: count first preferences
Allow eight minutes. Give groups this complete rule: each ballot counts once for its first preference; the option with the largest total wins. If totals tie, record a tie rather than invent a winner. There is no tie in today’s main packet.
Sort the slips into A, B and C piles, then enter their totals. A different pupil recounts before the group announces a result. Ask two separate questions: “Which option has the largest pile?” and “Does it have more than half of all twelve ballots?” Keeping those questions separate helps pupils distinguish a leading option from one supported by a majority of first preferences.
Rule 2: compare the top two using the recorded rankings
Allow ten minutes. Return the same slips to one packet. This second rule has two steps: retain the two options with the highest first-preference totals; then count every ballot once for whichever of those two it ranks higher. If the first step has a tie for a place, stop and report that the rule needs a tie procedure. A final equal count is reported as a tie. Our packet has a clear top two.
A and B remain available. On each slip, cross out C and find the first remaining option. The A-first and B-first slips keep their choices. All three C-first slips now count for B because they rank B above A. This is a recount using preferences already recorded, not a fresh vote or a chance to change a ranking.
One slip, one count. A transferred ballot moves to its remaining choice; it is not counted once for C and again for B. The final A and B piles must still add to twelve.
Check the counts and the explanation
| Option | Rule 1 | Rule 2 final count |
|---|---|---|
| A | 5 | 5 |
| B | 4 | 7 |
| C | 3 | Not retained |
| Total ballots counted | 12 | 12 |
Rule 1 selects A with five first preferences. Five is the largest count, but it is below half of twelve. Rule 2 selects B: its four first preferences plus the three C-first ballots give seven, compared with A’s five. Seven is more than half of twelve.
The explanation should identify the three C-first ballots and their B-over-A ordering. “More people were counted” is inaccurate: both rules count all twelve. Rule 2 uses additional preference information when a first choice is unavailable.
Choose a rule before knowing who benefits
Use ten minutes for discussion. Groups write a short recommendation for a future club decision. They must state a purpose, explain how the rule serves it, acknowledge one limitation and say how a tie will be handled. Invite them to consider ease of counting, strength of first preferences and willingness to accept another option.
A defensible response might favour Rule 1 because it prioritises first choices and is simple to check, while acknowledging that its winner can have fewer than half. Another might favour Rule 2 because the final comparison uses preferences between two remaining options, while noting that members must rank alternatives and that the method does not examine every possible group-choice question.
Ask: “Would you defend the same rule if your favourite option lost?” This moves discussion from the attractive result to the reason for the procedure. There is no single compulsory moral answer. Reward accurate counting and a clear trade-off rather than agreement with the teacher’s preferred rule.
Exit challenge: must the winner change?
Use the final seven minutes for a fresh nine-ballot packet: four rank A–B–C, three rank B–C–A and two rank C–A–B. Pupils apply both rules and complete: “Changing the rule does / does not always change the winner, because ___.”
Teacher check: Rule 1 gives A four, B three and C two. Rule 2 keeps A and B, and the two C-first ballots move to A. The final result is A six, B three. A wins under both rules. Use labelled piles, larger slips or spoken rankings for access; extend by asking pupils to invent a small packet producing a tie and explain which instruction is missing.
The CBSE Class IX Social Science curriculum, 2026–27, Part 1, theme 7 includes electoral systems and explaining elections. This original club model opens a discussion about decision procedures. Connect it with respectful school decision-making and, separately, the questions of honesty explored in “To Lie or Not to Lie!”. A transparent count gives that conversation something concrete to examine.
