Piggy Bank Math

A coin-counting game where you click pennies, nickels, dimes, and quarters to match a target amount before time runs out, then feed the piggy bank. Choose Penny Prospect (easy, all four coins) or Coin Captain (harder, limited coin sets and larger totals). Controls: mouse or tap to click coins and buttons, enter or space to continue.

Teaching Notes for Educators

Students build a target amount from pennies, nickels, dimes, and quarters, racing the clock.

The math: adding coin values (1, 5, 10, and 25 cents) to reach a total, which is skip counting by 5s, 10s, and 25s.
Two notations: totals under a dollar show as cents (75¢) and larger ones as dollars and decimals ($1.35), so students see both forms.
Strategy: Coin Captain limits students to two coin types at a time, which pushes them to plan a combination, and every target can be made with at least 3 coins.
Real life: making change, paying exact amounts, and budgeting all use this same reasoning.
Going over costs: a color-changing piggy bank shows how close the total is, and going over the target twice ends the round.
