Your students already feel supply and demand at the lunch table. Market Mayhem turns that instinct into understanding: the price moves because of what the room does, and the lesson — urgency is expensive, patience pays — is something they feel, not memorize. No prep, no jargon, no risk.
Open a browser, read the 3-minute script, play. Works on the projector, Chromebooks, or phones.
Flip from the no-money Kids version to order-types-and-liquidity Pro mode without re-teaching the rules.
Students watch their own urgency cost them — on screen, in real time. That memory outlasts any worksheet.
Kids mode suits roughly grades 2–8 (no money or jargon — just behavior). Pro mode suits high school and adult/PD groups, adding order types, liquidity, and time decay. Most teachers use both across a unit.
Instant access after checkout: a link to the printable companion kit (lesson plan, host scripts, rule cards, score sheets, spinner) plus the full game at thekeepmoreco.com/market-mayhem/. Nothing to install.
No accounts, no logins, no real money — ever. Kids mode can't "lose." It runs in any modern browser.
No. The KeepMore Company takes no commissions and sells no financial products. Market Mayhem teaches the behavior behind markets — that's the whole product.
