Counting Coins

Counting Coins teaches and reviews the value of coins with users. From the main screen, users are presented with four options. The “Match the Value” option presents users with a coin or combination of coins, and users must match the total value of the coins presented using a different combination of coins. For example, if a dime and nickel are presented, users must make 15¢ by dragging three nickels (or another coin combination) into the workspace and then tapping the “Check” button. The “Make the Total” option presents users with an amount of money, users must drag a coin combination into the workspace that equals that value and then tap the “Check” button. The “How Many Cents?” option presents users with a multi-coin combination. Users must add the coins’ value, enter the total value into the app, and then tap the “Check” button. For all three of these options, after the “Check” button is tapped, the app then informs users if they are correct or incorrect. If incorrect, users can enter a different amount, and if they are correct, users progress to the next problem. The “Show Values” option lets users drag multiple coins into the workspace and then tap the “Show Value” button. The app will then add the coins together and show users the coins’ total value.

Instructional Ideas

1. Teachers can have students practice their coin counting skills using the “Match the Value” or “Make the Total” options in this app. As they work, teachers can make sweeps of the room to monitor students and offer assistance as needed.
2. Once students are comfortable counting coins using this app, teachers can transition them from the practice exercises offered in this app to having them practice using real coins. One way to do so is for teachers to write an amount of the board (e.g., 47¢, 82¢, etc.), and students will have to combine coins to make that amount at their desk.
3. Once students have gained proficiency counting coins, teachers can have them count coins to solve word problems. For example, teachers could present students with a problem such as, “If Tommy bought three erasers from Sally for 21¢ and gave Sally a quarter to pay for it, how much change does Sally owe Tommy?” Students would answer this question by putting four pennies on their desk.
