Almost one thousand children have been caught carrying weapons in school in the last three years.
They include at least 80 primary school children, the youngest of whom was an eight-year-old caught with a knife.
Some 36 pupils were found with an assortment of guns, including two hand guns, seven air-powered weapons and 27 BB guns.
Of those found with weapons, 329 caught with items including an axe, a cut-throat razor and a stun gun were charged with a criminal offence.
Humberside Police have told us sixteen secondary school pupils have been caught since 2011 and 6 were chargedJayne Walmsley, whose son Luke was murdered at Birkbeck College in North Somercotes in 2003 aged 14, said: "Something is happening to the society we live in.
"We need to think and educate these kids. It's got to stop. We've got to do something about it."
Patrick Regan, CEO of charity XLP, which was founded in response to a school stabbing, added: "There's a culture of fear that needs to be broken down."
The Government said it had given teachers powers to take action if they suspect a pupil has brought a weapon into school.
"Teachers can now search pupils without consent, confiscate prohibited items and use force to remove disruptive pupils from the classroom when necessary," a spokesman for the Department for Education said.
"We've also given heads the final say on expulsions by removing the right of appeal panels to put pupils back in the classroom."
However, Chris Douglas, a youth worker with St Giles Trust, which engages with young people caught up in crime, warned the use of weapons is a growing problem.
"We're not hearing about stabbings because they're becoming more common," he said.
Last year, a study by UCL and charity Kids Company found half the young people working with the organisation had seen someone shot or stabbed in their community in the past year.
In 2009, the then-Government announced new measures to curb the problem of weapons in schools after a spate of attacks against children.
There were plans to introduce airport-style metal detectors as part of a violent crime action plan.
But campaigners are concerned the issue has disappeared from public discourse, leaving children vulnerable.
"Sometimes it's a bit like banging your head on a brick wall," Mrs Walmsley said.
"Schools won't admit to the problem because all they want is more pupils for more money."
