Students will launch the market math investigation by testing percentage-based money scenarios from everyday purchase cards, revising an early calculation after a quick teacher check, and identifying questions they want to investigate about price changes, value, and budgeting.

Students will refine a focused money investigation question, test and revise calculation methods with real purchase data, and produce a team investigation plan that explains how they will gather, organize, and analyze evidence about how percentages change cost, profit, and savings.

Students will present their market math display boards or slide presentations to visitors, use a final self-check to strengthen calculations and conclusions, and explain how percentage reasoning led to smart money decisions.
