## Partitive and Quotitive Division

An important distinction in division is between situations that call for a partitive (also called fair share or sharing) model of division, and those that call for a quotitive (also called subtraction or measurement) model of division. This distinction is critical for the division of fractions work that students begin in 5th grade. Students should have exposure to both types of division starting in 3rd grade.

The distinction is summarized in this diagram.
