Teams of amazing mathematicians took number-crunching to the extreme to be named this year's challenge champs.
Northgate High School, in Dereham, recently hosted the second annual Primary Team Maths Challenge.
Teams of four mathematicians from Beetley, Dereham Church of England Junior Academy, Hockering, North Elmham, Scarning, Garvestone, Thomas Bullock and Necton descended on Northgate High School to see who would be crowned this year's champions.
Pupils were tested on their understanding and application of core skills, as well as communication and team work, and logic. They also took part in a relay round which saw pupils running across the hall to collect and answer questions before tagging their team mates.
There were only four points separating the top three teams - third place, Scarning, second place, Thomas Bullock, and in first place was Beetley.
A spokesperson for the event said: 'Congratulations to all the teams who took part – there was some fantastic maths and teamwork on display.'
