Tell the room they will trade first and pay attention to what makes exchange hard.
“We’re starting with a trade game. If exchange feels clumsy, pay attention — that’s the lesson.”

A printable run sheet for the flagship History of Money workshop. Use it beside the projector deck when you need timing, exact transitions, and the same frame → play → debrief → explain → bridge logic in your hand.
Release the room and resist rescuing it too fast.
“Try to improve your position. If you get stuck, stay with it for a minute.”
Ask what had to line up for a trade to happen, then introduce double coincidence of wants.
“What kept breaking before a trade could actually happen?”
Connect barter pain to saleability: some goods become widely accepted because they trade better than others.
“People start accepting some goods because they know those goods will trade again later.”
Say clearly whether you are closing into Block 03 or extending into Medici.
“Now we choose: institutions and trust, or what breaks money again.”
Leave the room with a clean next question about money reliability.
“If money solved barter, what happens when the money itself starts failing people?”
What success looks like
- You can point to one real failed trade from the room.
- Participants explain barter inefficiency before you define it.
- The word saleability lands as intuitive, not academic.
- Medici is framed as phase two, never as the starting point.
- The room leaves with one narrative arc: barter problem → money solution → trust tradeoffs → modern fragility.
- The branch into Medici or Block 03 feels deliberate, not improvised.
Use this 20-second explanation
“You just felt why barter breaks: trade depended on perfect matching. Money emerges because people start accepting the most saleable good, which turns one hard trade into two easier ones.”
- Then point forward: the next question is whether that money stays trustworthy.
- Use Block 03 for monetary failure, or Medici for institutions and trust.
When to add Medici
- Do add it for ~60 minute classes, deeper workshops, or institutional trust discussions.
- Skip it for short conference rooms where Block 03 is the better next move.
- Hand out role cards only after the money lesson is fully understood.
- Debrief the tradeoff: institutions solve problems and create new trust dependencies.
Keep the explanation layer close
- Block 02 overview for the clean post-play explanation.
- Appendix for round references and logistics.
