Maths has become the tastiest lesson of all in one Norfolk school, where swift sums add up to a sweet treat.
North Walsham Infants on Manor Road has introduced 'chocolate bingo' sessions for children and parents.
And the experiment - which sees milk and white chocolate buttons used as markers on bingo boards - has brought parents flocking in and improved the standards of maths among the youngsters.
Headteacher Clare Fletcher said: 'It's a drive to get parents supporting their children with maths and simple numbers in a fun way.
'We had the first session before Christmas and have repeated it every term for each year group.
'We use an online bingo generator. All the children have a bingo board and work in pairs - either with another child or a parent.
'I call out the sums, and we have the buttons as markers. We have 20-odd parents that come along for each afternoon when we run it with the children.'
Mrs Fletcher added: 'The children absolutely love doing sums and it's such a fun way for them to learn about numbers. Everyone likes bingo and everyone likes chocolate - you can't go wrong really.'
