Slice a pizza into sectors, stand them in a row, and box the shape — the box only fits at height r and base πr, so area = πr² appears; then size pizzas to area orders and crust ribbons to 2πr.
Players cut a pizza into sectors, line the slices up into a near-parallelogram, and box it with a height in inches and a base in π-inches — the box only closes at height r and base πr, so A = πr² is built, not memorized. Later rounds drag the crust (or the diameter bar) to fill area orders like 25π in² or ≈ 78.5 in², and set crust ribbons to 2πr. It targets the classic slip of squaring the diameter instead of the radius. Best for Grades 7–8.
