Students join on any phone or laptop with a code. No student accounts.

Every student runs the same small design and print shop for a year. Clients pay net-30, payroll is due every two weeks, rent is due on the 1st, taxes land every quarter, and a credit line charges interest. Each month brings a decision and a piece of news: a late client, a big order that needs materials up front, a machine breakdown, a competitor poaching staff. The ledger shows profit and cash side by side, and they disagree.

What students learn

  • ✓Profit is on paper; cash is in the bank; businesses die from running out of cash
  • ✓How net-30 payment terms create a gap between doing the work and getting paid
  • ✓Payroll and rent are due whether or not customers pay on time
  • ✓When borrowing is smart, what interest costs, and why taxes surprise people

How it works

  1. 1Every student runs the same small design and print shop for one year.
  2. 2Each month brings news and a decision: a late client, a big order that needs materials up front, a broken machine.
  3. 3Clients pay 30 days later. Payroll, rent and taxes are due on time no matter what.
  4. 4The ledger on each phone shows profit and cash side by side, and they often disagree.
  5. 5The recap shows who stayed alive, who ran out of cash, and why.

A 27-minute lesson plan

Before (5 min)

Ask: can a business that's making a profit go broke? Take a vote. Don't give the answer yet.

Play (12 min)

Play the full year (about 12 minutes).

After (10 min)

Retake the vote. Ask a student who was profitable but ran short of cash to explain what happened.

Discussion questions

  • What's the difference between profit and cash?
  • Why did getting paid in 30 days cause problems even when you had plenty of work?
  • When was borrowing on the credit line a smart move? When was it a mistake?
  • Which surprise hurt the most, and how could you have planned for it?

Teacher tips

  • Great as an opener before a unit on financial statements: students will want to know why their cash disappeared.

Questions teachers ask

Do students need accounting knowledge?+

Can one student play alone?+

Yes, it works with a single player as well as a full class.
