Review: Official website of world maths day 2010, where you can register your kids for free. Students play at home and at school against other students around the world in live games of mental arithmetic. Each game lasts for 60 seconds and students can play up to 500 games, earning points for each correct answer. The students who answer the most questions appear in the Hall of Fame and earn prizes. Students cannot select their level but will move up as they progress. Matheletics users do not need registration. Homeschoolers can participate as individual students.
Suitable for ages: 5 – 18 years
