Total dots

80

Multiplication

8 × 10 = 80

Division

80 ÷ 8 = 10

• Count the rows, then count how many are in each row: 8 rows of 10 makes 8 × 10 = 80.
• As repeated addition that is 10 added 8 times: 10 + 10 + 10 + 10 + 10 + 10 + … = 80.
• Turning the array on its side does not change the total, which is the commutative property: 8 × 10 = 10 × 8 = 80.
• The same picture shows the two division facts as well: 80 ÷ 8 = 10 and 80 ÷ 10 = 8.
