The stamp game is one of the Montessori favourites! Typically it is used by children (ages 4-7) for both static and dynamic addition, subtraction, multiplication and division. After being introduced to the process 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 represented by each stamp.
