Three point one four one

eight nine and so on –“Pi-ku” from NCTM Illuminations

When I picked up my son from school today, he excitedly reported the “Pi Day” activities in his class and told me about the tiny lemon pie tucked inside his lunch bag. So in honor of my kiddo’s excitement over $π$ , I’m dropping in today to share a “pi-ku” with a side of pie–or a side of “pi-ku” with a healthy serving of pie.
