After being introduced to the processes of the decimal system using the golden bead materials the Stamp Game provides opportunities for individual practice in the operations of addition subtraction multiplication and division. In a step towards abstraction the quantity and symbols of the decimal system are combined and are represented by each stamp. The Stamp Game material consists of a wooden box and lid with six compartments containing green blue and red wooden stamps printed with 1 10 100 and 1000. The box also contains color-coded division skittles and color-coded discs for representing zero in the divisor.
