For grades 4 to 6: What is Pi? Pi (Greek letter “π”) is the symbol used in mathematics to represent a constant — the ratio of the circumference of a circle to its diameter — which is approximately 3.14159. Pi Day is an annual opportunity for math enthusiasts to recite the infinite digits of Pi and talk to their friends about math. Let’s try some Raspberry Pi.
