Students would see how far an Ozobot would travel for 3, 5, 7, 9 and 11 seconds and then construct a scatter plot of the data. This lesson is where we introduce lines of best fit, and equations of lines of best fit. This lesson replaced one where we had students measure their height, arm span and head circumference and ask the question: "Is there a relationship between a person's height and arm span and a person's height and head circumference?". Students would measure their height, arm span and head circumference, create scatter plots, lines of best fit and equations of lines of best fit. When we first thought of changing this lesson to using Ozobots, one of the questions I had was - "Which lesson will be better?" With the body measurements, I liked that the starting question had to do with relationsh...
