AIM: What are Unit Rates? Do Now: Solve for x: Periods 3, 7, 9 1. Periods 5, 8 1.

BIG IDEAS A unit rate is a rate with a denominator of 1

Steps to calculate Unit Rate: 1. Set up given ratio 2. Set equal to X 1 3. Solve using cross multiplication 4. Label your answer

Apple Juice! What is the unit rate of apple juice? (cost per ounce)

Now, onto the classwork… During the classwork, you will quietly work on your own or with a classmate

Summary: What is a unit rate? Provide a description and at least one example.
