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
- Predict whose wait shrinks the most when the same six people swap a line per helper for one shared line — then run both clocks and see if you were right.
- Before running it, guess what happens to the separate lines when one slow order lands at the front of a row.
- Predict: if every order took the same time, would one line still beat many lines? Test it and explain why.
Where it shows up in real life
- The single snaking rope-line at airport security
- Banks and post offices that call 'next customer, please' to one shared line
- Picking your own checkout lane at the grocery store and getting stuck behind a full cart
