Understanding the Distributive Property

This lesson teaches how to write equivalent expressions using the distributive property. It begins with breaking down multiplication problems into smaller parts for easier solving. The lesson then introduces variables to represent changing quantities and demonstrates the distributive property with examples involving candy bags and amusement park costs. By the end, students learn to simplify expressions and calculate total costs using the distributive property.

What is the main purpose of using the distributive property in multiplication?

• To increase the numbers involved in multiplication

• To eliminate the need for multiplication

• To break down multiplication problems into smaller, easier parts

• To make multiplication problems more complex

How can the number 7 be broken down using the distributive property in the example 8 times 7?

• 7 can be broken down into 6 plus 1

• 7 can be broken down into 4 plus 3

• 7 can be broken down into 3 plus 4

• 7 can be broken down into 5 plus 2

What does the variable C represent in the context of the lesson?

• The total number of candies

• A constant number of candies

• The number of bags

• A changing quantity of candies

How can the expression 5 times C be written without the multiplication symbol?

• C+5

• C5

• 5C

• 5+C

In the candy bag example, what does the expression C plus 3 represent?

• The initial number of candies in each bag

• The number of bags

• The number of candies in each bag after adding 3

• The total number of candies in all bags

What is the equivalent expression for 5 times C plus 3 using the distributive property?

• 5C plus 3

• 5C plus 3C

• 5C plus 15

• 5 plus C plus 3

In the amusement park example, what does the expression 20 plus D represent?

• The cost for one friend to rent a locker

• The cost for one friend to enter the park and rent a locker

• The cost for one friend to enter the park

• The total cost for all friends

How is the expression 4 times 20 plus D simplified using the distributive property?

• 80 plus 4D

• 4D plus 20

• 80D

• 4 times 20D

What is the total cost for 4 friends to enter the park and rent lockers?

• $80D

• $20D

• $20 plus 4D

• $80 plus 4D
