### Lesson Objective

The lesson is aligned to the Common Core State Standards for Mathematics – 6.RP.3.a Ratios and Proportional Relationships – Make tables of equivalent ratios relating quantities with whole-number measurements, find missing values in the tables, and plot the pairs of values on the coordinate plane. Use tables to compare ratios.

### Lesson Procedure

**Make tables of equivalent ratios relating quantities with whole-number measurements, find missing values in the tables, and plot the pairs of values on the coordinate plane.**Example

A passenger airplane flies at a cruising speed of approximately 550 miles per hour (mph).

- Complete the table to show the distance travelled for each of the number of hours the airplane flew at this cruising speed.
