Middle Grades Math: You Are What You Eat
by Texas Instruments #### Overview

Students are introduced to modeling linear data through an investigation of comparing grams of fat and calories in fast food hamburgers.

#### Key Steps

• Students use linear regression to investigate the relationship between the number of calories and the number of grams of fat in fast food hamburgers.

• Students set up and equation to relate calories vs. grams of fat by plotting the data as a scatter plot, then find the line of best fit.

• Students compare the equation found with the regression equation. They examine how similar or different the equations are.
