Heather Brostron, primary directress (preschool/kindergarten teacher) at OakHaven Montessori School in O’Fallon, MO, demonstrates to a group of parents how the stamp game works. Preschool and kindergarten age children (in OakHaven’s primary program) have fun playing this game, which:
- offers the opportunity for individual practice with all four operations
- reinforces the work with the golden beads
- consolidates the understanding of the processes that are acquired previously thorough the collective work
- furthers the sensorial experience of place value
