Multiplication

3 × 5 = 15

Division

15 ÷ 3 = 5

• Count the rows, then count how many are in each row: 3 rows of 5 makes 3 × 5 = 15.
• As repeated addition that is 5 added 3 times: 5 + 5 + 5 = 15.
• Turning the array on its side does not change the total, which is the commutative property: 3 × 5 = 5 × 3 = 15.
• The same picture shows the two division facts as well: 15 ÷ 3 = 5 and 15 ÷ 5 = 3.
