What is a Numerace?
Numerace is a free, 30-minute online math competition for grades 3–7 where the whole class solves problems as one team.
We run several events per year. During competition week, you can run a 30-minute Numerace at any time, with separate sessions for one or more classes.
The whole class competes as one team against other classes, with one shared score, so every student can contribute to the final result.
Low-floor, high-ceiling problems range from easy to tough. Students choose the topics and challenges that feel right for them.
