Solving for Unknown Amounts Using the Commutative Property of Multiplication

The video tutorial explains the commutative property of multiplication, which allows factors to be rearranged without changing the product. It introduces the concept of turnaround facts, where multiplication equations can be written in different orders but yield the same result. The tutorial also demonstrates how to use this property to solve for unknowns in multiplication problems, emphasizing that recognizing turnaround facts can simplify problem-solving.

What does the commutative property of multiplication allow you to do?

• Multiply numbers in any order

• Add numbers in any order

• Subtract numbers in any order

• Divide numbers in any order

Which of the following is an example of a turnaround fact?

• 9 - 3 = 3 - 9

• 6 * 7 = 7 * 6

• 4 + 5 = 5 + 4

• 8 / 2 = 2 / 8

How can the commutative property help in solving 5 * 7 = 7 * blank?

• By adding 5 and 7

• By subtracting 5 from 7

• By recognizing that the missing factor is 5

• By dividing 7 by 5

If you know 8 * 12, what can you infer about 12 * 8?

• It equals a different product

• It equals the same product

• It is double of 8 * 12

• It is half of 8 * 12

What is the missing factor in the equation 8 * 12 = blank * 8?

• 16

• 12

• 24

• 8
