About the Pi Day word search

It is an IRRATIONAL number, so its DECIMAL expansion is INFINITE and never repeats. The symbol is a GREEK letter, ARCHIMEDES was one of the first to estimate it, and EINSTEIN was born on Pi Day in 1879. And of course, there is PIE. The word list runs easy-to-medium and suits students from about 9 up. More in the math word searches and the March word searches.
