After being introduced to the decimal system using the Golden Bead Material, the Stamp Game provides opportunity 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’.
This material is contained in a wooden box with 6 compartments. Stamps are organized according to hierarchical colors (green, blue and red) and according to the numbers stamped on them: 1, 10, 100 and 1000. The material also includes skittles and colour counters.
