120-90-60 Fluency - Debate Edition

Two groups each deliver their 2-minute argument, then a 90-second summary of the opposing argument, then a 60-second rebuttal. Compresses the full rhetorical arc — claim, comprehension, counter — into seven minutes under escalating time pressure.

Extends the 120-90-60 Fluency principle from monologue to argumentation. Every round serves a different rhetorical function rather than just shrinking the same content.

Procedure

1. Split into two groups. Assign each a position on a debatable proposition (or give each group a different sub-topic they'll defend).
2. Group prep (5–10 min): keyword notes only. Plan the 2-minute speech collaboratively; decide which member delivers which section.
3. Round 1 — Speech (2 min each side): Each group delivers its argument. Listeners take notes.
4. Round 2 — Summary (90 sec each side): Each group summarises the opponent's argument from notes. Not their own — the other side's.
5. Round 3 — Rebuttal (60 sec each side): Each group attacks the weakest opposing point.
6. Debrief: which group understood the other's argument most fairly? Which rebuttal landed?

Why It Works

• Three distinct cognitive demands: producing an argument, comprehending and paraphrasing the opposition, then attacking it. Each stage trains a different skill.
• Active listening required: Round 2 punishes groups that didn't listen during Round 1. Accountability is built in.
• Argument steelmanning: summarising opponents fairly before attacking is the hallmark of quality disagreement — a rare skill.
• Time pressure compresses: the 60-second rebuttal forces prioritisation of the single strongest counter.

Variations

• Fishbowl version: 4 debaters in the inner circle; rest of class is outer audience noting arguments. After three rounds, inner and outer swap.
• Flip sides after Round 1: groups argue position A in Round 1, position B in Rounds 2 and 3. Forces genuine engagement with both sides.
• Written counterpart: the same three-stage structure compressed into written paragraphs. Good pre-writing for argumentative essays.
• Extended: + Round 4 (30 sec): a single-sentence "final word." Ultra-compression.

Tips

• Topic choice matters. Pick propositions students can argue both sides of — not settled questions. "Should universities be free?" works; "Is water wet?" doesn't.
• Round 2 is where learning happens: the summary-of-opposition phase is both the most demanding and the most educationally rich. Don't shortcut it.
• Protect the 60-second rebuttal: learners want to keep going. Enforce the cutoff strictly — compression is the point.
• Pair with functional language prep: discourse markers for disagreement (although, nevertheless, however) and for hedging (one could argue) should be pre-taught.
