Exploring the Commutative Property of Multiplication

The video tutorial explains how to use arrays to represent multiplication sentences and demonstrates the commutative property of multiplication. It shows that the order of factors does not affect the product, using examples like 3x6 and 6x3, and 4x8 and 8x4. The lesson concludes with practice exercises for writing multiplication sentences from given arrays.

What does the multiplication sentence 3 times 6 represent?

• Multiplying 3 by 3

• Multiplying 6 by 3

• Adding 3 six times

• Adding 6 three times

How can we represent 3 times 6 using an array?

• 6 rows of 3

• 3 rows of 6

• 3 rows of 3

• 6 rows of 6

What happens when we rotate the array representing 3 times 6?

• It represents 6 times 6

• It represents 3 times 6

• It represents 6 times 3

• It represents 3 times 3

What important property of multiplication is demonstrated by rotating the array?

• Identity property

• Commutative property

• Distributive property

• Associative property

Which of the following is true about 4 times 8 and 8 times 4?

• One is greater than the other

• They are equal

• They cannot be compared

What does the array representing 4 times 8 look like when rotated?

• It represents 4 times 4

• It represents 4 times 8

• It represents 8 times 4

• It represents 8 times 8

How can we write the multiplication sentence for an array with 2 rows of 5?

• 5 times 2

• 2 times 2

• 2 times 5

• 5 times 5

What is another way to write the multiplication sentence for an array with 2 rows of 5?

• 5 times 5

• 2 times 5
