Numbers came to life at Nelson Academy in Downham Market when the school took part in a maths-inspired fundraising day.
Pupils went to school dressed in number-themed outfits ranging from dice and dominoes to calendars to raise money for the NSPCC.
Each class chose another method of fundraising including a two pence trail, sorting coins in a jar and a toy and book sale.
Lessons were focussed on number activities and there were also break time activities, such as painting by numbers.
Staff and pupils also took part in number challenge competitions last Friday.
The school’s maths lead Davina Nyarko said: “The whole school was involved and it was a really good day.
“We hope to have raised around £250.”
