This activity is a real world application for finding the percent of a number/whole. The "store" is throwing a sale and items are 10, 25, 50 and 75% off. Students walk around the "store" and determine original cost, percent off, new price and amount saved. This activity can be used as an assessment, practice, review or extension activity for finding the percent of a number. A lesson plan is included with store items and note sheet.
