Understanding Unit Rates

This lesson introduces the concept of rates, distinguishing them from ratios by using real-world examples. Ratios compare the same units, while rates compare different units, such as price per item. The lesson provides examples of unit rates, like cost per gallon and speed per hour, to illustrate how rates function in everyday situations. By the end, students should understand the difference between rates and ratios and how to apply unit rates in various contexts.
