Pupils are turning teacher when their grandparents return to school to be taught how to surf the internet.
The sessions for grandparents are a first for the school
Around 30 senior citizens will attend lessons at Ysgol Bryn Hedydd in Rhyl, north Wales with the help of their grandchildren.
The Grandparents to Schools Day has been organised by the charity EverybodyOnline, which is aimed at helping people to use the web.
Two lessons will be held on surfing the net and sending e-mails.
Head teacher Phillip Gallagher said the school was keen to work in partnership with EverybodyOnline, which is supported by BT and Microsoft.
"We are looking forward to bridging the generation gap," he said.
Mr Gallagher said he hoped pupils and grandparents would benefit from the sessions, with both able to learn from each other.
The school, which has 489 pupils, has recently taken delivery of 18 new laptop computers after a long-running fundraising campaign.
Debbie Holmes, project officer for EverybodyOnline in Rhyl, said: "The aim is to show to grandparents the benefits of using the internet. And it also gives the children the chance to show off a little to their grandparents.
"If I'd said to my grandparents we are going surfing they would think we were going on Rhyl beach."
Mrs Holmes said lack of confidence was the main problem for grandparents - and many parents - in using the web.
When grandparents visit schools they are shown many of the uses they can make of the internet, including online banking or sites which offer free goods.
According to the charity, the ward of Rhyl West was chosen as a designated ward for the EverybodyOnline project because connectivity in the area was low.
