This very simple app provides a fine introduction to adding coins, but it is not engaging and does not help students effectively achieve mastery. Students are shown realistic looking coins on the bottom half of the screen and a target value. The student drags the correct combination of coins to the top half of the screen to achieve the target value. The counter at the top of the screen adds the coin values for the student, so the student does not need to add the coins independently at any time. The student can move coins back and forth as much as necessary to achieve the solution, but cannot move to the next problem until the right answer is achieved. There is nothing to excite or engage a young student, but the app can be a reasonable starting point for familiarizing a child with how coins look, their values, and how they can add up to different combinations. Note: This app was originally reviewed for iPhone/iPad. Some differences might apply.
