Adopt-A-Minefield is partnering with the National Union of Teachers (NUT) to roll out a fundraising appeal across 30,000 UK schools.
The Get Stuffed appeal has a "conservative
target of £500,000, and aims to encourage pupils in 5 per cent of schools across the country to raise funds for child-related projects.
The NUT's involvement will include writing a joint letter to union representatives in schools and running an article in Teacher magazine, which goes out to 27,000 establishments in the UK.
"We've been talking to the NUT for some time about the education and awareness issues surrounding landmines,
said Alexandra Lagelee, director of Adopt-A-Minefield. "One-third of people affected by landmines are children and there is a huge benefit to getting kids involved in raising money to help with our international projects."
The Get Stuffed campaign is part of a global drive to raise funds to assist the charity's mine clearance programmes.
The UK's contribution will form a large chunk of the worldwide target of $3 million. Other participating countries include Canada and Sweden.
Lagelee said that the money generated from Get Stuffed would go mainly to the charity's projects that help children in landmine areas.
The charity launched last June and previously ran a campaign that raised £15,000 by targeting a primarily adult audience.
