Pi Day online scavenger hunt
If you want to broaden your scavenging horizons, consider a Pi Day internet scavenger hunt appropriate for Grades 5 and up, where students are instead searching the internet for different π-related objects.
Don’t feel limited by our pi scavenger hunt ideas, of course! You can adapt this Pi Day scavenger hunt activity for kids as young as four or five years old by asking them to hunt for 10 real-life circles. Or, you can challenge high schoolers to find another way the symbol π is used in math or science other than representing the constant approximately equal to 3.1415. Also, check out these fun Pi Day activities for high school students for even more ways to celebrate.
