Paper strips
Cards or slips of paper
glue/tape/staples
Introduce to students that pi is the ratio of a circle's circumference to its diameter.
Have each student use the string to measure the circumfernce of their head.
Have students (likely with a partner) measure the diameter of their head.
Divide these two measurements to get an individual approximation of pi.
Use the paper strips to create a headband, and attach a card with the individual pi approximation to the headband.

Introduce to students that pi is the ratio of a circle's circumference to its diameter.
Have each student use the string to measure the circumfernce of the pie.
Have students measure the diameter of the pie.
Divide these two measurements to get an approximation of pi.
Students record their approximation on a class list, and the class can then calculate the mean approximation to see how close they got to pi
oatmeal pies or moon pies are ideal becuase the are individually wrapped. Students can do the math while the pie is still wrapped, then open and enjoy.

This activity can also be done with ANY circular objects. Consider students choosing any circular object from the classroom to complete this activity.

Pi SkylineGraph paper
colored pencils or markers (optional)
On graph paper, use colored markers or pencils to have students graph the digits of pi using a bar graph format.
Once their pi-line skyline is created, invite them to color in the “buildings” and sky, complete with pi-in-the-sky constellations.
