Welcome to Problem Challenge!


Problem Challenge is a mathematics problem solving competition aimed primarily at children in years 7 and 8. It is organised by John Curran and John Shanks, retired members of the Department of Mathematics and Statistics at the University of Otago, with extensive secretarial help from Leanne Kirk, also of that Department.

Children participating in the competition attempt to answer five questions in 30 minutes on each of five problem sheets, which are done about a month apart starting in April.
