Tap multiplier chips onto a price bar — 20% off then 8% tax is ×0.8 ×1.08 — dial the single percent a chain equals, and chain ÷ chips to walk a final price back to the original.
A price bar sits on a percent ruler and each percent change becomes a multiplier chip: the player chains ×0.8 for 20% off and ×1.08 for 8% tax, and the bar rescales to show the compounded price in any order. Single mode gives the chain and asks for the one percent change it equals (×1.1 ×1.1 is +21%, not +20%); reverse mode gives the final price and the player chains ÷ chips to divide back to the original. The decoy chips are the classic errors — ×0.2 for 20% off, adding the percent back to undo a discount, adding successive percents instead of multiplying. Best for Grades 7–8.
