More than 3,000 pupils from 10 Sheffield schools devoted a day to making sure they are safe while online.
Westfield School, Sothall, joined forces with its nine feeder primaries to support Safer Internet Day 2014.
The secondary school helped organise the event with Waterthorpe’s Emmanuel Junior and Waterthorpe Nursery Infants, Beighton’s Brook House Juniors, Beighton Nursery & Infant and Reignhead Primary, Halfway Junior, Halfway Nursery Infant, Mosborough Primary and Westfield’s Shortbrook Primary.
The aim was to promote e-safety and encourage pupils to use technology safely and responsibly.
Normal lessons were suspended in favour of sessions looking at issues including potential dangers from online friends, and how to use the internet safely.
Pupils also took part in a competition which saw them designing posters promoting e-safety.
The day also featured a workshop for parents and children at Westfield.
Student ICT leaders ran the event, showing a film titled Watch Your Image and offering information and advice.
Family learning tutors were also involved, giving parents tips on how to supervise youngsters’ internet use.
Nationally, only 45 per cent of families currently use internet parental control systems.
Helen Stokes, Waterthorpe Nursery Infants School headteacher, said: “From a very young age, the internet is an important and integral part of children’s lives today.
“It is important for children and their parents to understand how to use technology safely to protect them from the risks we face through electronic communications.
“As a family of schools who work closely together we are able to get the message across to a whole area of the city at the same time.”
The day also had a positive aspect, with schools showcasing many of the creative things their youngsters are doing online.
