BUY WHAT YOU CAN AFFORD

decimals · adding and subtracting money

To add and subtract money.

BUY WHAT YOU CAN AFFORD is a Grade 5 money game for adding and subtracting decimal amounts. Two players work through purchase-style questions on game cards, including a shared question that both answer, then compare and check their work at the end. The money context gives decimal computation a practical purpose and asks students to reason about totals, affordability, and change.

Use it for partner review when students are ready to apply decimal addition and subtraction to money situations. Because both players eventually check the work together, the game can prompt useful conversations about calculation choices and errors.
