Open to schools, individuals, and homeschoolers alike, this
free global event awards minted medals, world cups, and prizes,
and recognizes each participant with a certificate.
Begun in 2007 — when over 287,000 students from 98 countries
correctly answered 38,904,275 math questions over the course of
48 hours — World Maths Day has "united the world in numbers"

as World Maths Day expanded to become the World Education Games
and UNICEF joined as an official worldwide partner.
This year's World Maths Day starts in the U.S. on the morning
of Tuesday, 5 March, with challenges lasting for as long as an
hour or as little as one minute.
Freely downloadable PDFs include a teacher guide, World
Education Games poster, and Frequently Asked Questions:
