   Pi Day Activity Book on USB 5pi ($15.70)  A 500MB USB drive packed with plenty of pi puns, games, lessons, facts, figures, articles, and more! An excellent resource for your classroom for Pi Day or any day that you are looking to inject something interesting and unique into your curriculum. 

   Backwards Unit Circle Clock 5pi ($15.70) 
Our clocks are finally back in stock!
Wait?! What time did you say it was? pi/2 past 2pi? Oh, okay, I have pi/6 more minutes until my class.
Have this powernerd conversation while confusing/impressing your friends/students/fellow teachers and nerds with this clock that goes backwards!
But, why does it go backwards?That's a great question. It goes backwards because it has the image of the unit circle on the clock. When you read the unit circle, you read it counterclockwise. Even better, the unit circle starts at the xaxis, so this clock mimics that by starting in the 3 o'clock position!
This is great for the classroom, too, if you are a) teaching trig or b) just want to keep your kids from looking at the clock to see when class will be over!
