This manipulative uses United States currency, both coins and bills. Images of bills include a circled number to identify their value: one, five, ten, twenty, or fifty dollars. The coins (pennies, nickels, dimes, quarters, and half dollars) should be easily identifiable, but it may take a little practice.


The manipulative provides practice with three different operations:

Make a Dollar shows you a set of coins, from which you are to drag coins into the box that together make up a dollar. There will often be more than one way to make a dollar from the given set of coins. For example, you can use either five pennies or one nickel, and if there are two quarters and a half dollar, you can make 50 with either set. When you have made a dollar, click Check. After having checked, you can drag coins out of the box and replace them with a different set to add up to the same value and Check again. You may want to see how many different ways you can make a dollar from the same set.

How Much Money asks you to total the value of the displayed bills and coins and type the value in the box. Be sure you know how we write an amount of money, using decimal notation and be careful to remember the difference between $15.10 and $15.01. When a response is typed in, the Check button will tell you "That is correct," or that you have too much or too little.

Pay Exact Amount You are to drag coins and bills into the box to add up to the specified value. As with the other options, the Check button will let you know if the amount in the box is too much, too little, or the correct value. If you have either too little or too much in the box, you can change the contents of the box and Check again.
