The Surf Smart, Stay Safe guide was created by Fibrus Broadband in collaboration with Cumbria Police.
It is full of puzzles and useful advice to help children start discussions on online safety, including cyberbullying and password protection.
The pamphlet is designed to help children who may spend a significant amount of time online during the summer holidays.
As well as the distribution of the booklet, Fibrus and the police also visited some schools and took part in community events to speak to children about the dangers of the internet.
Beaconside Primary, Calthwaite CofE School, Clifton School, and Culgaith CofE School were all part of the campaign.
Detective Constable Lee Clark, from Cumbria Police’s cyber and digital crime unit, said the booklet and school visits were valuable in starting discussions on online safety.
He said: “They are an opportunity to speak about the challenges and risks and how best to keep themselves safe online.
“Fibrus has been really good at pulling the events together.
“The leaflets have been useful, covering some key points that they learn about in schools and that we also talk about as well.”
Linda McMillan, group chief people officer from Fibrus, said: “We’re so glad that children all around Cumbria are finding our online safety booklet useful.
“From community coffee mornings to school visits like this one in Cockermouth, it’s been fantastic to see young people sharing their digital knowledge and learning from adults too.
“These conversations are so important and we’re proud to be supporting communities in Cumbria to connect on and offline.”
