Division can be used to find the size of a part of a set. This is called sharing, or partition division. When division is used to find the size of a part, a number is divided into equal parts.


1. There are 12 cookies. They are divided equally among 4 people. How many cookies does each person get?

12 4 = 3

Each person gets 3 cookies. Thus, the size of each person's part, or share, is 3.

2. Daynna, Taylor, and John went blueberry picking. Together, they picked 15 pints. When they got ready to go home, they shared the blueberries equally. How many pints did each person have?

15 ÷ 3 = 5
Thus, each person's share of blueberries was 5 pints.
