Division

120 ÷ 10 = 12

• Count the rows, then count how many are in each row: 10 rows of 12 makes 10 × 12 = 120.
• As repeated addition that is 12 added 10 times: 12 + 12 + 12 + 12 + 12 + 12 + … = 120.
• Turning the array on its side does not change the total, which is the commutative property: 10 × 12 = 12 × 10 = 120.
• The same picture shows the two division facts as well: 120 ÷ 10 = 12 and 120 ÷ 12 = 10.
