New York State Common Core Math Module 1, Grade 6, Lesson 16
Lesson 16 Student Outcomes
• Students recognize that they can associate a ratio of two quantities, such as the ratio of miles per hour is 5:2,
to another quantity called the rate.
• Given a ratio, students precisely identify the associated rate. They identify the unit rate and the rate unit.
Lesson 16 Summary
• A ratio of two quantities, such as 5 miles per 2 hours, can be written as another quantity called a rate.
• The numerical part of the rate is called the unit rate and is simply the value of the ratio, in this case 2:5. This means
that in 1 hour, the car travels 2. 5 miles. The unit for the rate is miles/hour, read “miles per hour”.
