First, click on the 3 dots on the left side of the screen. Then click on the shapes button. Next, click on the circle. Finally, click on the 3 dots and select the circle that is empty inside. Use either the pencil or marker to write either a Q for quarter, D for dime, N for nickel or P for penny. You can duplicate the circle by clicking on the 3 dots and selecting duplicate. Remember to use the least amount of coins that you can. For example, for 47 cents, I would you 1 quarter, 2 dimes and 2 pennies, not 4 dimes and 2 pennies and definitely not 47 pennies!!
