Pi Day Pie Sale is a fast-paced math game where students act as pie shop cashiers and price different kinds of pies using π = 3.14 and the correct formula for each pie type. Players measure the pie’s diameter with a movable, expandable ruler, calculate the price with the on-screen calculator, and submit their answer to complete sales and earn revenue. In timed mode, students race the clock to make as many accurate sales as possible, then receive a printable score report at the end.
