It’s Pi Day! We’re not sure how the mathematical constant is celebrating, but for us here at Sesame Workshop it’s a great opportunity to look back at Philip Glass’ “Geometry of Circles,” an animated short from 1979 set to the music of the famous minimalist composer. Using interesting animated shorts like “Geometry of Circles” to explain mathematical concepts is just one of the ways we help prepare children for their primary and secondary education. The origins of a child’s ability to understand complex concepts like pi (when you think about it, the notion of a number with an infinite decimal representation is, in the truest sense of the word, awesome) lies in the introduction to numeracy and basic mathematics that *Sesame Street *strives to provide.

Happy Pi Day! There ain’t no party like an irrational number party because an irrational number party don’t stop (literally).
