A mother has been left horrified after she saw a nursery rhyme teaching kindergartners how to survive a school shooting.

Georgy Cohen posted a picture of the rhyme which was hanging up in the kindergarten class in Somerville, Massachusetts, that her five-year-old daughter will attend in the fall.

In a disturbing sign of the times, the poem - sung to the tune of Twinkle, Twinkle, Little Star, teaches young children what to do in case of an active shooter.

It reads: 'Lockdown, lockdown, lock the door

'Shut the lights off, say no more.

'Go behind the desk and hide. Wait until it's safe inside.

'Lockdown, lockdown it's all done. Now it's time to have some fun!'

The post has already been liked and shared more than 60,000 times with many other parents sharing their outrage that the spate of school shootings had inevitably led to this.

Many contrasted it with their own childhoods when the worst they had to worry about at school was a fire drill.

'This should not be handing in my soon-to-be-kindergartener's [sic] classroom,' Cohen wrote

'This should not be handing in my soon-to-be-kindergartener's [sic] classroom,' Cohen wrote, adding that she didn't blame the school, but the current climate which has already seen 23 school shootings where someone was hurt or killed this year.

'The school is doing exactly what they need to be doing, and I am glad for it,' she said.

'My issue is with the political & cultural factors that brought us to this sad state. Please talk to your legislators about the need for gun reform.'

She and Somerville Public Schools declined to identify the school, but district officials confirmed it was the work of one teacher and is not used across all of the city's schools.

The Somerville district enrolls about 5,000 students in a suburb north of Boston.

In a statement, Superintendent Mary Skipper and city Mayor Joseph Curtatone applauded the teacher's creativity, but they lamented that lockdown drills have become as common as fire drills.

Just last month, in Santa Fe, Texas, shooter Dimitrios Pagourtzis opened fire in an art room, leaving ten dead and another ten injured (pictured, his classmates mourn)

'As much as we would prefer that school lockdowns not be a part of the educational experience, unfortunately this is the world we live in,' they wrote. 'It is jarring - it's jarring for students, for educators and for families.'

There has been almost one school shooting a week, on average, since January.

Just last month, in Santa Fe, Texas, shooter Dimitrios Pagourtzis opened fire in an art room, leaving ten dead and another ten injured.

But the worst shooting this year took place in Parkland, Florida when a 19-year-old former student began shooting students and staff members with a semi-automatic AR-15 type rifle. 17 people were killed, and 17 others were injured.
