Building a 'we don't laugh at mistakes' classroom in the first two weeks

The most important thing that happens in your classroom in the first two weeks of the year isn't a phonics lesson or a maths starter. It's the moment, somewhere around day three, when a child gives a wrong answer in front of the class — and the rest of the class either laughs, or doesn't.

If they laugh and you don't intervene firmly, you've just established a culture. From that day onwards, any child considering raising their hand to attempt a hard answer will weigh up the social cost. Many will keep their hands down. The brave ones will put themselves forward; the cautious ones won't. By half term, you'll have a classroom where the same six children answer everything and the rest are passively present.

If they don't laugh — or if they start to and you stop them — you've established a different culture. Children gradually realise that getting things wrong in front of others is genuinely safe here. Hands go up more. Children try answers they're unsure about. Discussions get richer. By half term, you have a classroom that thinks together.

The work to set this up is largely done in the first two weeks. Here's how.

Why this matters more than you'd think

A lot of education research clusters around one finding: children's willingness to attempt hard things in front of others depends almost entirely on whether they think they'll be judged for getting it wrong.

This isn't a wellbeing point — it's a learning point. Children who don't put their hands up don't get the chance to articulate their thinking. They don't get the corrective feedback. They miss out on the cognitive work of formulating an answer. Over a year, the gap between children who attempt and children who hold back compounds.

The single biggest predictor of whether a child will attempt is what happens to other children who attempt. If their mistakes are met with respect, attempts go up. If their mistakes are met with smirks or sighs, attempts go down. Children watch each other very closely; you don't have many days to set the standard.

What to do in the first two weeks

A specific list, in roughly the order you'd do them.

### 1. Get a wrong answer on day one — and praise it specifically

Plan for this. Ask a question deliberately designed so that some children will get it wrong. When one does, your response is the foundation for the rest of the year:

> 'That's a really useful answer, thank you. Do you know why it's useful? Because lots of children might think the same thing, and we can talk about it together. Let me ask the class — who can tell me why this answer is on the right track but isn't quite right?'

A few things this does: it explicitly says wrong answers are useful; it stops the class hearing the answer as 'wrong' (it's 'on the right track but not quite'); it invites the rest of the class to engage with the thinking rather than just notice the mistake.

You'll do this dozens of times over the year. The first time matters most.

### 2. Tell children explicitly what you expect

Don't assume. State it. Ideally on day two, after children have settled in slightly:

> 'In our classroom, we don't laugh at people's answers. We don't sigh, we don't roll our eyes, we don't whisper to our neighbour. If someone gives an answer that turns out to be wrong, we look interested, because their answer might help all of us. If you find this hard, that's okay — we'll all practise it together.'

This is more powerful than it sounds. Children often laugh at wrong answers because they're nervous and they don't know what else to do. Telling them what they SHOULD do gives them a script.

### 3. Use 'rough thinking' explicitly

A phrase to introduce in week one: 'rough thinking.' Children share rough thinking — half-formed ideas, attempts, guesses. The understanding is that rough thinking isn't expected to be right.

> 'Anyone want to share some rough thinking? You don't need to be sure.'

When a child shares rough thinking, your response is engaged and curious — never 'right or wrong.' Then you might ask: 'Anyone else have rough thinking that goes a different way?'

This separates 'sharing thinking' from 'showing you got the right answer.' Children who would never want to give a 'wrong answer' will give 'rough thinking.'

### 4. Catch and stop the smallest reactions

Children testing the culture will do so with small things first. A barely-audible snort. An eye-roll between friends. A 'pfft' at someone's answer. These are the moments to stop the lesson — gently, briefly, but unmistakably.

> 'Sam, I noticed you laughed when Maya was answering. Maya was being brave. We don't do that here.'

Don't make it bigger than it needs to be. Don't make it a whole-class lecture. Just notice, name, move on. The rest of the class is watching how you handle this. They'll either learn that the rule is real, or that the rule is empty.

You'll probably need to do this 5-10 times in the first two weeks. After that, far less.

### 5. Praise the trying, not just the getting it right

A lot of teachers say 'good job' when a child gives a correct answer. This is fine, but it can subtly reinforce that the goal is to be RIGHT — not to attempt.

A more useful frame:

> 'Good for you for trying that — that's exactly the kind of thinking I was hoping for, even though we'll need to look at it again.'

> 'I love that you put your hand up even though you weren't sure.'

Praise the bravery and the thinking, not the rightness. Right answers will get praised naturally; trying answers need explicit recognition.

### 6. Share your own mistakes out loud

Children don't think teachers make mistakes. (They do, but the children are wrong about how often.) If you make a small mistake — get a date wrong, miscount, mispronounce a word — name it.

> 'Oh, I made a mistake — I said the Vikings arrived in 793 AD, but I just want to check that... yes, 793. Okay, that one was right. But you should always check what I tell you, because I get things wrong sometimes too.'

This does two things. It models that grown-ups make mistakes and survive it. And it gives children permission to query you, which is a much more useful classroom dynamic than children passively accepting whatever you say.

### 7. Share a famous mistake

In the first two weeks, find a famous example of a productive mistake. Penicillin was discovered by accident. Velcro was invented because a man was annoyed by burrs sticking to his dog. Post-it notes came from a failed glue. The chocolate-chip cookie was invented when someone forgot to fully melt the chocolate.

> 'Sometimes the best things come from getting something wrong. Today let's see what mistakes can teach us.'

Make this a recurring theme, not a one-off. By half term, your class should associate 'mistake' with 'useful', not 'embarrassing.'

What undoes this work

A few things that quickly undo a 'mistakes-are-useful' culture, in case you want to avoid them.

**Sarcasm in any form.** A teacher's sarcastic 'Wow, that was an interesting answer' destroys two weeks of culture-building in five seconds. Children pick up the cue immediately.

**Letting some children mock without consequence.** If the class clown gets away with mocking other children's answers, every other child watches and learns that the rule is for show.

**Stopping at the right answer too quickly.** The teacher who says 'Great, that's right, moving on' deprives the wrong-answer-givers of the chance to see why their thinking didn't quite work. It also positions the conversation as a competition rather than a collaboration. Slow down. Talk through several answers, including some wrong ones, before reaching the right one.

**Praising right answers excessively while skipping over wrong ones.** Children notice. The currency of the room becomes 'rightness,' which is exactly what you don't want.

**Treating 'I don't know' as failure.** It's not. Sometimes the most useful thing a child can say is 'I don't know but I'd like to think about it.' This is a much better answer than a guess. Honour it.

What to expect

If you do this work well, here's what you should see by half term:

- Multiple hands up for hard questions (not just the same six children) - Children correcting their own thinking out loud ('Wait, no, I think I was wrong, it should be...') - Children listening to each other's answers, not just waiting for their turn - Children comfortable saying 'I'm not sure but I think...' - Genuinely productive whole-class discussions about ideas

By Christmas, this culture becomes self-reinforcing. New children who join mid-year pick it up from the others within days. The atmosphere of the room is thoughtful rather than performative.

The takeaway

The single most important thing you do in the first two weeks of the year is establish what happens when someone gets something wrong. Get it right early, defend it when it's tested, and the rest of the year teaches itself slightly easier.

Get it wrong — let mockery slide, praise rightness over trying, treat wrong answers as obstacles — and you'll spend the next eight months wondering why so few of your children put their hands up.

Two weeks. Done well, the dividends pay for the entire year.
