Speaking Activities › Rebuttal Pong
A class debate activity for KS2, in pairs
Rebuttal Pong is a whole-class debate cut down to something a primary class can actually do. Two children, one motion, thirty seconds each — one arguing for, one against. Then the class votes on who was more convincing. It takes five minutes, it needs no preparation, and it teaches the one thing a written debate never does: how to answer a person who has just disagreed with you.
What is Rebuttal Pong?
Rebuttal Pong is a paired speaking activity in which two children debate a single statement in short, timed turns. One speaks for the motion, one against, and they alternate — so each turn has to answer the one before it, like a rally. The rest of the class listens and votes at the end, which is what stops it becoming a private conversation between two children at the front.
How do you run a class debate in pairs, step by step?
Put the motion on the board and give the two speakers ten seconds to decide who is for and who is against — or let the app decide, which is fairer and faster. Speaker one gets thirty seconds. Speaker two then gets thirty seconds, and their first sentence must respond to what they just heard. Two rounds each is plenty. Then the class votes, and you ask the deciding question: what was the strongest thing you heard?
What is a rebuttal, and why is it the hard part?
A rebuttal is a reply that takes on the other side's actual argument instead of restating your own. It is the hard part because it cannot be prepared. A child can rehearse a speech about school uniform at home, but they cannot rehearse an answer to the specific reason the child opposite them just gave — they have to listen, hold it in their head, and respond. That is the skill this activity is built around, and it is why the timer is short.
How long should each turn be?
Thirty seconds is the default and it is the right starting point for most of Key Stage 2 (US grades 3–6). Twenty seconds suits Year 3 and 4, or any class doing this for the first time, because a short turn is far less frightening and a child who dries up has not failed publicly for very long. Forty-five or sixty seconds is for Year 6 and above (grades 6–8) once they can fill the time without padding.
Which year groups is it for?
It works from Year 3 to Year 9 (US grades 3–8). Younger children need the sentence stems on the board and a motion about something they already have opinions on — homework, sweets, school uniform. Older children can handle motions with no obvious right answer, and can be pushed to concede a point before answering it, which is a genuinely sophisticated move.
From the classroom
The mistake is letting them prepare. Give a class two minutes to plan and you get two speeches read off a whiteboard pen scribble, delivered past each other, and no rebuttal anywhere — because a prepared child stops listening the moment they have something to say. Run the first round completely cold instead. It is worse, and that is the point: they discover they need to listen. The other thing worth doing is picking the pair yourself rather than asking for volunteers, and picking a quiet child second. Going second is easier than it looks, because the first speaker has just handed them something to disagree with, and a child who will not start a conversation will often happily finish one. With Year 3 I keep the motion daft on purpose — whether cats are better than dogs gets more genuine argument than anything about school rules.
What usually goes wrong?
Three things, and they are all fixable. The speakers talk to you rather than to each other, so stand at the back and they will turn. The second speaker ignores the first and delivers their own speech, so make the first sentence a rule: it must start I disagree, however… or that is a fair point, but…. And the class watches passively, so give them the vote before the debate starts, not after — knowing they will have to judge is what makes them listen.
Can I choose what they debate?
Yes, three ways. Pick a ready-made set — school life, animals and nature, technology and the future, food and health, or the wider world. Generate your own on any topic you type, pitched at your class's age, so the debate can sit inside the lesson you are already teaching: the Romans, the water cycle, the class book. Or write your own motions straight in. Whichever you pick, you see the full list before it reaches the class and can edit any of it.
Can I print a debate planning sheet?
Yes — two pages. The debate planner is an A4 sheet each child writes on: a line for the motion, columns for arguments for and against, a box for the other side's strongest point and your reply to it, and the sentence stems along the bottom. The second page is a set of cut-out motion cards carrying the motions you actually chose, so groups can run it at tables without a screen.
How is it different from a normal class debate?
A normal class debate needs teams, preparation and most of a lesson, and in a class of thirty it means about six children speak. Rebuttal Pong is two children at a time for one minute, so you can run six pairs in the time a single formal debate takes, and everyone else has a job throughout. It is a starter, not an event.
| Use it for | How | How long |
|---|---|---|
| An oracy starter | Two pairs, 30 seconds each, class votes | 5 minutes |
| Warming up persuasive writing | Debate the motion, then write the argument you lost | 25 minutes |
| A whole-class debate lesson | Print the planner, prepare in fours, then run pairs at the front | 45 minutes |
| Wet play or a spare ten minutes | Straight in, no planner, daft motions | 10 minutes |
Do I need an account?
No. You can open this, set it up, and model a worked example to a class before anyone asks you for anything — the setup screen and the Model it first screen are both open. Starting the activity uses a free trial token, and a Sage Pro subscription lifts the limit. Nothing here is behind an email wall.
