Pi Day Explorations Pi Day Project Rotate through Pi stations. Use string and a ruler to measure the circumference of various circle shaped goodies, and record measurements in Customary or Metric units. Use a ruler to measure the diameters, and record them in the same units. Determine the of circumference to diameter, and identify how many times the circumference goes across the length of the diameter. After completing rotations, reflect on your findings and Pi.

Pi Project
	Poor 1 pts	Good 2 pts	Excellent 3 pts
Completion of All Stations	Poor Project was missing two or more stations/quarters of the circle.	Good Project was missing one station/quarter, or had one that was incomplete.	Excellent Project had all four quarters/stations completed.
Measurement Accuracy	Poor One or more circumference:diameter ratio was one whole measurement unit off from 3.14.	Good One or more circumference:diameter ratio was more than 0.5 measurement units off from 3.14.	Excellent All circumference:ratios were within 0.5 measurement units to 3.14.
Reflection	Poor No evidence of a relationship between the distance around a circle, and the distance across, nor reference to Pi, was evident.	Good Partial evidence of a relationship between the distance around a circle, and the distance across, as reference to Pi, was evident.	Excellent Clear evidence of a relationship between the distance around a circle, and the distance across, as well as a reference to Pi, was evident.
Clarity and Neatness	Poor Project lacks neatness necessary to inform reader.	Good Project presents information and problem neatly but lacks organization for clarity.	Excellent Wow! Project is neat and colorful. Viewer can easily read and understand the project.
