Checker Board Materials

The Checker Board materials provide a concrete representation of multiplication within the decimal system. Through the manipulation of bead bars and number tiles, children are able to visualize place value, perform multiplication operations, and develop a deeper understanding of how quantities change across the hierarchies of the decimal system. The Decimal Checker Board extends this work to include decimal quantities, helping children make connections between whole numbers and decimal fractions.

These materials are each sold separately.
