Money Pieces help students visualize and understand money values and relationships. Two versions of coins and bills are provided: virtual currency pieces that replicate the appearance and relative size of U.S. coins and the dollar bill, and area money pieces. Area money pieces represent the values of coins and the dollar bill using an area model in which 1 square unit is equal to a penny. Nickels, dimes, quarters, and half dollars are represented by collections of squares equal to their value. In this way, the area pieces can be used to model and compute with fractions and decimals.
