I’ll approximate this with my MathCounts kids, using squares and hexagons. Archimedes worked up to a 96-gon, but that is beyond us. High school students may enjoy another Archimedes puzzle.**MacTutor’s History of Pi**

Follow the adventures of from II Chronicles 4 to 20th century Germany, including the still-open question: Is “normal”?**How Pi Was Almost Equal to Three in Indiana**
