ChangeMaker is a money math game where students take on the role of a cashier helping a customer buy a gift. The register shows the total price and the amount the customer paid, and players must determine how much change to give back. This game supports K–5 math skills by building understanding of subtraction, counting on, place value, and money concepts. Students practice comparing amounts, finding the difference between two values, and thinking flexibly about dollars and cents. As they play, they strengthen real-world problem-solving skills connected to making purchases and giving accurate change.
