Four sessions on what actually sets a price — built around one apple stand in one small town.
Devon Ashby sells apples in Corbin Falls. Your student reads the supply and demand schedule, finds equilibrium, then a frost damages the harvest and everything moves. The unit insists on the distinction everyone gets wrong: a shift in supply versus a movement along the curve.
It closes the way every Trade-Offs unit closes — the town considers capping the price of apples, and your student has to argue both sides properly, scored on how fairly each case is made rather than which one wins.
That closing argument is the part that works better at a kitchen table than in a room of thirty. You take the other side.
