Money skills are perennial problems for the primary teacher. Although no easy answers exist, it is useful to consider what skills and concepts are required for working with money.
Here is a list of the money ideas and skills typically required in the primary grades:
The names of our coins are conventions of our social system. Students learn these names the same way that they learn the names of any physical objects in their daily environment - through exposure and repetition.
The value of each coin is also a convention that students must simply be told. For these values to make sense, students must have an understanding of 5, 10, 25 and so on. More than that, they need to be able to think of these quantities without seeing countable objects. Nowhere do we say, "this is five", while pointing to a single item. A child whose number concepts remain tied to counts of objects in not going to be able to understand the values of coins. Coin value lessons should focus on purchase power.
A worksheet for coin recognition as well as coin value, as an example:
The remaining items in the list of skills are all a form of mental computation and/or compound skip-counting. To name the total value of a group of coins is the same as mentally adding their values except that there are no numerals visible. Ironically, most state standards require coin counting before they require students to do the symbolic sum mentally.
Making change is the only time time that students are asked to add on to find a difference, so it is a very foreign type of task. Furthermore, children are generally asked to create the difference or change in a prescribed manner. Finally, they must do it with coins instead of numerals.
Because adding on to find a difference is such a valuable skill - much easier than using the usual subtraction algorithm - it makes sense to give student a lot of experience with adding on to find differences before asking them to make change. As students become more skillful at adding on, they can see the process of making change as an extension of a skill already acquired.
A great place to start is to use little ten-frame cards in activities to encourage students to first add up to the next ten, although that is not the only method:
Actual "shopping" activities can follow once they have a good understanding of change:
