Instructions for Use

Change Maker provides students with practice counting money and estimating differences.

To use Change Maker, choose a currency by clicking on the flag of a country, and a difficulty level. Mentally subtract how much money you expect to get back when you pay for an item. If you get the answer correct, the amount of change is added to your piggy bank. If you get the answer wrong, the correct amount of change is subtracted from your piggy bank. The more money you get in your piggy bank, the harder the questions will get.
