The Stamp Game in Montessori:
This material is typically introduced when children are about 4.5-5 years old and have worked with concrete math materials, such as the Golden Bead Material, number rods, and Sandpaper Numbers.
The Montessori Stamp Game aims to support children in transitioning from a concrete understanding of the decimal system—using golden beads for collective exercises—to a more abstract comprehension. Additionally, it introduces them to the concepts of addition, subtraction, multiplication, and division with multi-digit numbers.
Unlike the previous math materials the children have worked with prior to the Stamp Game, the control of error with this activity is the child’s own understanding!
