This worksheet is a fun handout of two activities to do on Pi Day! Outside of this activity you will need the Little Debbie Oatmeal Creme Pies and a hula hoop. The Oatmeal Creme Pie requires students to measure the diameter of the pie and then calculate the area and perimeter. It also uses a previous skill of unit rates to find out how much creme would be needed to fill the pie. The hula hoop activity uses Pi to find out how many revolutions the hula hoop made.
