If grade-level appropriate, start by introducing π as the ratio of a circle’s circumference to its diameter. Archimedes (287-212 BC) was the first to calculate π. He used an approach that drew on the Pythagorean theorem to calculate the approximate circumference of a circle by adding up the sides of inscribed triangles.
