Created by Illuminations: Resources for Teaching Mathematics, students model linear data in a variety of settings that range from car repair costs to sports to medicine. Students will construct scatterplots of two-variable data; interpret individual data points; make conclusions about trends in data, especially linear relationships; and estimate and write equations of lines of best fit. The site offers insight into: learning objectives, materials needed, an instructional plan, assessment options, extensions, compliance with NCTM standards and expectations and even references to external sites.
