World Math Day runs for 48 hours, starting on March 25 in Australia and on March 24 in most U.S. locations (due to time differences). It is the world’s largest online math competition, an international celebration of mathematics where 10 million students have answered more than 1 Billion questions. World Math Day is FREE for all and is hosted on the Mathletics platform. All registrants have free access to Mathletics starting on March 12: https://www.3plearning.com/world-Math-day. The 2026 theme, United by Numbers, celebrates the belief that everyone can learn and excel at mathematics when given the right support. Teachers and students need not be Mathletics users to participate.
