*Equation of a Line and Line of Best Fit*

The lesson really gets kids curious about how they can accurately predict outcomes of events. How long does it take to pass a ball around to 100 people? Find out using slope, the equation of a line, data collection, and line of best fit! Here, students actually gather data by tossing a tennis ball to 1, then 2, then 3, students until all of the students in the class have been included. Using that data, students create a scatter plot and determine a line of best fit to answer the question of how long it would take to pass the ball to 100 people. Enjoy!
