11/23/2010 ©Evergreen Public Schools Hollywood Budgets Teacher Notes Big Ideas : 1)The axes of a scatterplot does not have to start at zero. The axes need to be consistent from the first number on the axes. 2)You make better predictions when your graph is scaled to match the data. Task : Students predict how much the movie Avatar will gross in the U.S. Have students work in pairs. Give half the class the worksheet with the x -axis starting at zero, and give the other half the worksheet with the x -axis starting at 200. DON’T LET THEM KNOW THERE ARE 2 DIFFERENT FORMS. Have students present their predictions. Hopefully half with the zero axis will find the task much more difficult than the half with the 200 axis.
