Signal or Noise
Fast rounds where the class decides whether a piece of data actually predicts anything, or is just noise.
A clue appears. Fifteen seconds to call it.
- Satellite images show a factory car park is fuller than usual. A celebrity tweeted a snack brand once.
- Three buttons: RISE, FALL, or NOISE.
- Faster correct answers score more.
- After each round the real answer appears with a one-line explanation.
It builds the habit of asking whether something actually tells you anything.
- That is the skill underneath data handling, media literacy and half of economics.
- The fifteen-second timer stops overthinking.
- The explanation after each round means nobody guesses blindly for long.

What happens, in order, with timings. Nothing is live yet. This page is just for you.

Set the rules
Seconds per question, how many questions, how often standings show. Defaults are sensible, so you can just press go.

Put the code on the board
A six-digit code and a QR go up. Names appear as people join. Nothing starts until you press start.

They join in seconds
Scan or type the code, pick a name, done. No account, no app, no email address.

Run a round
The clue goes up with a countdown. You can see how many have answered without seeing who.

One decision, three buttons
That is the whole phone screen. Big targets, no scrolling, locks the moment they commit.

Reveal and discuss
The answer, how the room split, and why. The rounds where the room splits evenly are the ones worth pausing on.

What we’d tell you over tea.
- The rounds where the class splits evenly are the ones worth pausing on.
- Fifteen seconds feels short and should. Lengthen it only for younger classes.
- Run it as a warm-up before the Stock Market Simulation, since the two teach the same instinct.
