Before class
- Open Explore. The ticket price starts at $60.
- The band is fictional and demand is a straight-line model; the numbers are for discussion, not about a real artist.
Hook 5 min
- "Have you ever tried to buy tickets the minute they went on sale and found them sold out, then listed for three times the price?" Take stories.
- "Was the ticket too cheap or too expensive? Today you find out."
Explore 15 min
- Read the scene at $60: a line out the door, a reseller with a sign, a sold-out seat map. Then read the graph: where does the gold price line cross demand?
- Pairs drag the price up until the line disappears and seats start going empty. "What price makes the fans who want in match the seats?"
- Pairs try the scenarios one at a time: Song goes viral, Bad reviews, Second night and Price cap $75. For each, they record what moved (demand or supply) and what happened to the line and the empty seats.
Make sense 10 min
- "Why is supply a vertical line for one night?" (The arena has a fixed number of seats.)
- Name the gap below the market-clearing price: a shortage. "Who captures the gap between the face price and what fans will pay?" (Often a reseller.)
- "A price cap is meant to help fans. What actually happens to the line and to resale prices?"
- "With a second night, the most money comes from a price that leaves some seats empty. Why?"
Apply 10 min
- Pairs switch to Tour. Demand is hidden. Each city has three nights.
- Pairs set a price, open sales and read the result: a line means too low, empty seats mean too high. Each night adds a point on the demand curve.
- After night three, demand is revealed with a score. Pairs compare scores and strategies.
Exit check 5 min
On a card, sketch a supply and demand graph for a sold-out show priced too low. Label the shortage. Then answer: "Who gains and who loses when tickets are priced below the market-clearing price?" Graphs with the shortage above the clearing price show who needs Explore again.
Support and stretch
- Support: use the arrow keys on the graph to move the price in small steps and read the numbers.
- Support: give pairs a table with columns for price, fans who want in, seats and line or empty seats.
- Stretch: "Is pricing below the market-clearing price ever a good choice for an artist? Why might they do it?"
- Stretch: research a real ticketing controversy and explain it with the graph.
Short on time
- Explore at $60, then drag to the clearing price (7 min).
- Price cap $75 as a class (5 min), then the exit card (5 min).
