March 1, join more than 2 million students across the world who will celebrate World Math Day in a quest to set a new world record for answering math questions! If you're interested in participating (for free!), make sure to sign up before Feb. 28.
Questions come in five categories: addition, subtraction, multiplication, division and simple equations. The website attempts to match players of similar ability levels. Results are shown immediately after each round.
Individuals and school classes can register. At our school, each class is assigned a 30 minute slot for a computer lab. That way each of the kids gets the chance to play a few rounds. They love racing kids around the world and I love that they're getting excited about math!
