It is almost here—March 14! The day when all math geeks (and friends of Einstein) unite. To celebrate this wonderful day we have put together a fun-filled lab full of hands-on activities to get your students excited about circles. Your students will see pi form before their eyes as they create a paper chain with its digits. The classroom walls will be polka dotted with circles labeled with area and circumference. Lastly, your funny bone will be tickled when your students display funny jokes about their favorite number. We promise you, after this day, your students will never look at a circle the same way again.
