This activity involves using pennies balanced on the end of a ruler to create a linear model. As pennies are added, distances from the edge are recorded. The distances and corresponding number of pennies needed are then added to a spreadsheet from which graphs and data are generated.
Before the Activity
Each student or group of students should have 10 pennies, a ruler, a TI-nSpire handheld, a copy of the attached worksheet, and a flat surface on which to work.
