A method and apparatus is described whereby a child or other person may learn to use two different notational systems for coins, such as cents and dollars, by following an ordered set of instructions that guide the matching of movable graphic symbols and coin-replicas onto identical graphics on a printed surface. In the example the user learns 1) to recognize and name a notational symbol corresponding to each of the two notational systems; 2) that the two different systems can be used to express the same amount of money; 3) to associate the physical manipulation of a coin or coin-replica simultaneously with both notational systems; 4) to calculate and physically assemble the amount of coins or coin-replicas of a given denomination that sum to the unit value of the second notational system; and 5) to calculate and physically assemble the amount of coins or coin-replicas of a mixture of denominations that sum to a requested amount. Additionally, a final evaluation step provides feedback and options relative to calculating the requested amount.
