Why do 5 rows of 3 and 3 rows of 5 both equal the same number?
Multiplication Property The Commutative Property of Multiplication states that when you change the order of the factors, the product stays the same. You can think of it as the Order Property of Multiplication.

So, 2 × __ = 3 × __.
So, 2 × 3 = 3 × 2

Math Idea
Facts that show the Commutative Property of Multiplication have the same factors in a different order.
2 × 3 = 6 and 3 × 2 = 6

Question 1.
Write a multiplication sentence for the array.

Answer:

Explanation:
The commutative property of multiplication states that for any a x b = b x a

Mathematical Processes
Explain what the factor 2 means in each multiplication sentence.
Answer:
In a multiplication sentence, the two numbers either side of the multiplication sign are called factors.
The number after the equals sign is called the multiple.
Explanation:
For example:
If you write the two smaller numbers the other way around as 5 × 3 = 15 instead of 3 × 5 =15,
this does not matter when talking about this array.
It would mean 5 lots of 3.

Write a multiplication sentence for the model. Then use the Commutative Property of Multiplication to write a related multiplication sentence.
