Plan together. Then go quiet.
Can your team agree on answers without seeing everyone’s question? Make a plan, find its limit, then compare it with a quantum model.

TWO ACTIVITIES. PLAY THEM IN THIS ORDER.
A team challenge, followed by a question about chance.
GHZ · SHARED CORRELATIONS
Can you cover all four question cards?
Three players lock an answer plan. Every fixed local plan misses at least one card; an ideal GHZ strategy can satisfy them all. See where the difference comes from.
CHSH · CORRELATION AND CHANCE
A better average. A guaranteed win?
Two players try to match answers—except on one question pair. Compare a local plan with the ideal quantum model, then explore why a short run can be misleading.
A PLAN, A PATTERN, A QUESTION
Players can talk while choosing their plan. Once the questions arrive, only their own question may determine their planned answer. The phone covers each private turn before passing to the next person.
These are ordinary classical simulations of ideal quantum distributions. The phone can see all the questions; a real Bell experiment has stricter physical conditions. Each modeled local result is random, so the correlations cannot send a chosen instant message.
The four-card challenge audits a locked plan. The classroom lab samples fresh, independent random questions. No learning-gain claim is made.
