All about pi and Pi Day. Includes pi formulas and equations.

To celebrate Pi Day, I created three fun activities that let kids get artsy while not losing a day of learning. That one above is a Pi Day Pennant for middle and high school students with area and circumference problems and fun pi facts on each pennant. Some of the circle problems ask students to combine their understanding of the two circle formulas by finding area given circumference, for example. A fun challenge!

In this collaborative activity celebrating Pi Day, students work with the circle formulas to find area, circumference, radius and diameter. Each pennant also includes a Fun Fact that students can read as they complete their circle problems. Once a pennant is complete, it can be hung along a string in your classroom to celebrate Pi Day!
