The Montessori stamp game is one of the most versatile math materials in the primary classroom. Children use color-coded wooden tiles stamped with 1, 10, 100, and 1000 to represent quantities and work through addition, subtraction, multiplication, and division with a concrete material that makes abstract operations visible. The work bridges the gap between the golden bead material and purely abstract arithmetic, giving children a satisfying, hands-on way to practice operations with large numbers. Key Features Color-coded wooden tiles for units, tens, hundreds, and thousands Includes skittles and counters for operation work Solid beech wood construction Box measures 11.8 x 9 x 2 in Educational Benefits A core Montessori math material that makes the four operatio Contentns concrete and accessible, building deep understanding of place value and arithmetic through independent hands-on work. Place value understanding with units, tens, hundreds, and thousands Concrete introduction to addition, subtraction, multiplication, and division Mathematical reasoning and problem solving Independent work and concentration Bridge from concrete to abstract arithmetic Ways to Play Build any number using the color-coded tiles and read it aloud Set up an addition problem and combine the tiles to find the sum Work through subtraction by removing tiles and exchanging when needed Use the skittles to set up simple multiplication and division problems
