This packet includes 2 Pi Day Printable posters (8.5 x 11 size) and a investigative activity. I used the 2 printables to add to a poster about pi day. The activity involves students finding circular objects and wrapping a string around them and then measuring the string. They will then calculate the circumference and diameter and divide. There are questions then about Pi and how they came to find answers close to it. Everything is in PDF format - no answer sheet provided because each students results will be different based on the items they measure. I always provide a variety of items to measure such as cups, bottles, bowls, soup cans, coffee cans, Clorox wipe containers, graduated cylinders, etc. The students really enjoy this activity.
