1. Malia sells 4 wristbands for $2.50 each.
a. How can you use multiplication to rewrite the addition sentence that you wrote in Lesson 3 to represent the amount Malia earns?
Addition Sentence:
= $2.50 + $2.50 + $2.50 + $2.50
THEREFORE:
Multiplication Sentence:
= 4 × $2.50
b. What is the product, and what does it mean in this situation?
In this situation, the product of the multiplication sentence represents the total amount of sales / money obtained from the sale of 4 wristbands sold for $2.50 each.
c. How does the product compare to the sum of the addition sentence?
The product of the multiplication sentence and the sum of the addition sentence are equivalent to each other in value. This is as they are both equivalent to $10.
2. Linnea sells 7 wristbands for $2.50 each. She tracks how much the fundraising goal decreases by for each wristband she sells.
a. How can you use multiplication to rewrite the addition sentence that you wrote in Lesson 3 to represent the amount the goal decreases by?

3. Emma sells 3 packages of wristbands and car decals for $3.75 each.
a. How can you use multiplication to rewrite the addition sentence that you wrote in Lesson 3 to represent the amount the goal decreases by?
Addition Sentence:
= $3.75 + $3.75 + $3.75
THEREFORE:
Multiplication Sentence:
= 3 × $3.75
b. What is the product, and what does it mean in this situation?
