On Friday, pupils and staff at schools across the country will show their support for those caught up in the tragedy by wearing green and donating money to the Kensington and Chelsea Foundation's Grenfell Tower Appeal.
More than 50 schools, across Kensington and Chelsea, Hammersmith and Fulham and Westminster, pledged to take part in the fundraiser within 12 hours of the campaign launching on social media amnd at least 100 schools across the country are now thought to be taking part.
In the early hours of Wednesday last week, a fire broke out inside Grenfell Tower in north Kensington and quickly engulfed the block.
At least 79 people are presumed to have died in the fire and the number could still rise in the coming days and weeks.
Peter Haylock, executive principal of Fulham College Academy Trust, whose schools started the #GreenforGrenfell campaign, told the Times Educational Supplement that the school community wanted to do something to help.
He said: "Some of the students wanted to do bake sales and activities to raise money, but we wanted to make it as powerful as possible and do something a lot more global than that.
"Our students really want to try and do something positive to try to help with such a tragic situation. As many schools as we can get wearing green on Friday, the better – it would be great to see it go national."
An ex-pupil from Fulham Cross Girls' School is missing following the fire, said its vice principal, Denise Fox.
She added: "The pupils know a lot of the people involved and you just feel so helpless. We wanted to do something to involve the whole community."
The campaign has quickly gained traction on Twitter with hundreds of messages from all over the country pledging support and commitment to go #GreenforGrenfell.
