Section 1
Understanding Rates and Unit Rates
Property
A ratio compares two quantities, often of the same kind.
A rate is a special type of ratio that compares quantities with different units (like miles and gallons, or dollars and hours).
In this Grade 6 lesson from Big Ideas Math Course 1, Chapter 5, students learn to define and apply rates, unit rates, and equivalent rates using ratio tables and double number lines. They practice writing rates from real-world situations, finding unit rates by dividing, and scaling equivalent rates to solve problems involving distance, earnings, and cost. The lesson builds foundational ratio reasoning skills essential for proportional thinking in middle school math.

A rate is a special type of ratio that compares quantities with different units (like miles and gallons, or dollars and hours).
Section 2
Calculating Unit Rates
A unit rate is a rate with a denominator of 1 unit.
To convert a rate to a unit rate, we divide the numerator by the denominator.
This gives us a denominator of 1.
