Teachers across the country took to social media on Friday to speak out against the president.
Using the hashtag #ArmMeWith, they listed things that would be more useful than weapons in a classroom.
It comes after Mr Trump told survivors of the deadly shooting at Marjory Stoneman Douglas High School, which killed 17 people, he wanted more guns in schools.
He promised “very strong” background checks at schools and said he supported allowing specially trained teachers to carry concealed weapons in a bid to prevent more horrifying school shootings.
“If you had a teacher who was adept with the firearm, they could end the attack very quickly,” he said, adding that schools could arm up to 20 per cent of its teachers to stop “maniacs” trying to attack them.
“This would be obviously only for people who were very adept at handling a gun, and it would be, it’s called concealed carry, where a teacher would have a concealed gun on them.”
His comments prompted wide spread criticism across America.
Many teachers took to Twitter to join the #ArmMeWith movement.
Noelle Clark wrote: “#ArmMeWith Snacks to feed my hungry students who can’t focus.
“#ArmMeWith A curriculum that focuses on student passions rather than raising test scores.
“#ArmMeWith a comprehensive school counseling program. DO NOT #ArmMeWith a gun. I teach to raise up the future, not to bury it.”
Another person wrote: “#ArmMeWith ways to help my students’ emotional needs, not a gun. They must feel safe in my classroom, not on edge.”
Darren Hause said: “I’m trained to teach, not to shoot. Instead of arming teachers with more gun, supply us with materials & resources we desperately need. From 1:1 devices to #2 pencils. From mental health care to healthy nutrition.”
NRA leader Wayne LaPierre supported the President’s call to arm teachers.
He said: “We must immediately harden our schools,” he said. “Every day, young children are being dropped off at schools that are virtually wide open, soft targets for anyone bent on mass murder.”
Since the Valentines shooting in Parkland Florida there have been public outcry and demands to enforce stricter gun laws.
On Tuesday, three busloads of students drove 400 miles from Parkland to Florida’s capital, Tallahassee, to request tighter gun control from the state.
The few who arrived early saw lawmakers in the Republican-dominated state Capitol rush through a vote refusing even to debate a ban on the sale of assault weapons. Those students in the balcony stood open-mouthed, crying at the vote.
Hundreds more students from schools across Florida joined the protest.
On Thursday students across the country participated in walk outs to demand tighter restrictions on who can buy guns and better services for mental health.
Former US President Barack Obama took to Twitter on Thursday to praise those who are taking a stand.
He said: “Young people have helped lead all our great movements.
“How inspiring to see it again in so many smart, fearless students standing up for their right to be safe; marching and organizing to remake the world as it should be. We’ve been waiting for you. And we’ve got your backs.”
