Materials note: This activity uses the Create A Graph online tool at https://nces.ed.gov/nceskids/createagraph/default.aspx, an application that enables students to independently and quickly create graphs. Thus, students need access to computers with internet connections for part of the Day 3 activity. For teachers and students who do not have internet access, an alternate worksheet is provided that uses Microsoft^® Excel^® to create scatterplots. In addition, another worksheet is available for manual graphing. See the Attachments section.
