How to use it
- Read the price and what is paid.
- Tap coins and bills to build the change. Tap one in the box to take it back.
- Press Check my change. If it is off, it says how much more or less.
- Press Show me how to see the count-up: start at the price and add up to the amount paid.
Ideas for class
- Set up a class store and have students make change at the board before they do it with real coins.
- Ask students to find a second way to make the same change with different coins.
- Compare the count-up with subtraction: $1.00 − 65¢ and 65¢ + 35¢ = $1.00.
- Use level 1 for grades 1 and 2 and level 3 for grades 4 and 5.
- Ask for the fewest coins that make the change.
