Maths was the winner on the day, as thousands of school pupils across the motu have competed for glory in a the country's biggest maths competition. The Times Tables Rock Stars Mathematics Competition was held earlier today, with the event involving two corresponding 30-minute quizzes across the North and South islands. Erica Stanford was keeping a keen eye on proceedings at a Christchurch school, and herself, was put to the times tables test. Adam Burns reports.
