In the coin tile view, there will be a coin box where you can arrange coin tiles to help you count the value. The darker 2×5 outlines allow for counting similar to a ten-frame.

Exchange: The bottom center area allows you to change coins for an equivalent group of coins. In the right half, place coins from the active workspace. In the left, coins from the bank. Any number of coins may be moved to either area as long as the total of both halves are equal.
