Intended for use on an iPad, SMART Board, or other touch screen device. Use your finger to press and drag the coins onto the purple area. Alternatively, coins can be clicked and dragged. All coins touching the purple area are added up. Drag coins to the trash can to delete or press the "reset" button all of the coins. The calculator will only add up to $9.99 (then it resets back to 0).
Designed to be used as a tool for students who may be struggling to add up coins. Please let me know if there are any bugs. Any feedback is greatly appreciated. Thanks!
