• Count the rows, then count how many are in each row: 4 rows of 9 makes 4 × 9 = 36.
• As repeated addition that is 9 added 4 times: 9 + 9 + 9 + 9 = 36.
• Turning the array on its side does not change the total, which is the commutative property: 4 × 9 = 9 × 4 = 36.
• The same picture shows the two division facts as well: 36 ÷ 4 = 9 and 36 ÷ 9 = 4.
