Middle Grades Math: Recipe: Unit Rate
by Texas Instruments

#### Objectives

• Students will use a ratio to create and plot points and will determine a mathematical relationship for plotted points.
• Students will compute the unit rate given a ratio.
• Students will predict ordered pairs based on a given ratio.

#### Vocabulary

• ratio
• unit rate
• linear relationship
• proportional relationship

#### About the Lesson

This lesson involves the use of a given ratio to plot sets of points within a real-world context.
As a result, students will:

• Recognize the linear relationship of the set of points.
• Predict ordered pairs based on the given ratio.
• Compute and use the unit rate for a given ratio.
• Recognize the set of points will include (0, 0) and (1, r) where r is the value of the unit rate.
