Decimal Chequer Board

The Decimal Chequer Board is a key Montessori material used in the Elementary Math curriculum to help children perform long multiplication and long division using large numbers. This felt-lined wooden board features 7 rows and 7 columns of colour-coded squares—green for units, blue for tens, and red for hundreds—visually reinforcing the hierarchy of the decimal system.

Through hands-on bead work and color cues, children build a deep conceptual understanding of place value, number positioning, and multi-digit operations. The material transforms abstract arithmetic into a concrete, tactile learning experience, allowing learners to confidently solve problems involving thousands, millions, and beyond. This board is essential for transitioning children from concrete to abstract arithmetic.
