Key Mathematical Ideas:

Computational strategies for multidigit division rely on the place-value system and properties of the operations.

Each visual, physical, or verbal representation of division highlights some aspects of the mathematics and obscures others.

Examining the reasoning that underlies division procedures, including the standard algorithm, provides a context for students to deepen their understanding of the place-value system and of the operations themselves.

Elaborations
