Multiplication

5 × 8 = 40

Division

40 ÷ 5 = 8

• Count the rows, then count how many are in each row: 5 rows of 8 makes 5 × 8 = 40.
• As repeated addition that is 8 added 5 times: 8 + 8 + 8 + 8 + 8 = 40.
• Turning the array on its side does not change the total, which is the commutative property: 5 × 8 = 8 × 5 = 40.
• The same picture shows the two division facts as well: 40 ÷ 5 = 8 and 40 ÷ 8 = 5.
