The numbers have added up for pupils at a West Norfolk school who have won two maths challenge competitions.

Sixteen pupils in class 6B at   Reffley Community School in King’s Lynn came out tops in an online contest run through Sumdog, an internet programme which has educational games based around maths, reading and writing.

More than 43,000 pupils countrywide signed on for the Christmas competition, which was contested by 6,999 classes. The 6B class won and classmates in 6GB finished seventh.

One pupil also finished third in the top ten for the number of correctly answered questions.

As a result of the victory, the school has won an iPad and 30 free internet subscriptions for Sumdog.

The win came hot on the heels of success for the school in a similar competition for Norfolk schools, which was contested by more than 6,000 classes.

Class teacher, Jason Brewer, said the competitions had improved the pupils’ mental maths skills through fun activities.

He said pupils took part in the competitions using the school iPads, or their own computers at home.

“They have a week to answer thousands of questions and the class average score is calculated,” said Mr Brewer.

He added the level of difficulty of the questions could be set by teachers and the aim was to make it a challenge.
