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

  1. "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.
  2. "Was the ticket too cheap or too expensive? Today you find out."

Explore 15 min

  1. 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?
  2. 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?"
  3. 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

  1. "Why is supply a vertical line for one night?" (The arena has a fixed number of seats.)
  2. 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.)
  3. "A price cap is meant to help fans. What actually happens to the line and to resale prices?"
  4. "With a second night, the most money comes from a price that leaves some seats empty. Why?"

Apply 10 min

  1. Pairs switch to Tour. Demand is hidden. Each city has three nights.
  2. 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.
  3. 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).
