Pi Day Midway

It's a very special Wednesday, ladies and gentleman. Not only is it Pi Day here in the states (it's celebrated in July, elsewhere in the world), but it's also time for this week's Carnival of Education. How lucky can one get? If you work up a hunger strolling the midway, head on over to PiDay.org to shop or send an e-card. Perhaps you might like to play some Pi Day Games or do some activities related to this unique number. Pi Day comes but once a year...
