Stamp Game is a Montessori Mathematical material in Montessori teachers training curriculum, utilized by an individual toddler to exercise the operations of addition, subtraction, multiplication and division. .The Montessori Math Stamp Game lesson comes at the end of the place value and decimal system work. The goal is to reinforce the four operations introduced with the golden pearls, but in a more abstract way. Numbers, the stamp game uses several small tiles on which the numbers one, ten, 100 or 1000 are stamped. Students use these “stamps” to replace the beads and chains they used previously, while still using something concrete to back up their arithmetic. work. Students start writing equations and write their answers by transcribing these stamps. Show the child how to line up the stamps for the first summand and then the second summand in vertical columns. Drag each column to the bottom of the workspace, count, and write them down. Ask the child to summarize their work at the end. Provide the necessary instructions to guide the child with the equations. Observe the child and then walk away from work.
