A question for the whole room
One story to open. A room full of ideas to test.
Ready in three steps
- Open the story.Read and try the first pages together.
- Pause for a prediction.At the story’s question, read its choices aloud. Invite a vote and ask, “What makes you think that?”
- Run it. Watch. Wonder.Choose the class’s prediction, run the experiment, and compare what happened with your guesses.
Different guesses are welcome. The experiment gives everyone something to rethink.
Something to put on paper
A one-page prediction and observation sheet. No answers included.
After the experiment: discussion notes
Talk about what happened
- Why do a bad row and bad column give two coordinates instead of two separate guesses?
- What is the difference between detecting damage and knowing exactly how to repair it?
- What would you trade for a code that protects against more possible mistakes?
Where it shows up in real life
- A scratched QR code that still scans
- A download corrected over a noisy connection
- Computer memory that quietly corrects a flipped bit
