Number pieces help students develop a deeper understanding of place value while building their computation skills with multi-digit numbers. Students use the pieces to represent multi-digit numbers, regroup, add, subtract, multiply, and divide.

This virtual version of our Base Ten Area Pieces is an open-ended educational tool, ideal for elementary classrooms and other learning environments that use laptops, iPads, Chromebooks, or Windows devices.

Number pieces are a key component of Bridges in Mathematics, second edition. Online preview available.
