One of the victims of the house fire in Chesterfield "always had a smile on his face", his headteacher has said.
Jordan Green and his nine-year-old brother Tyler were pronounced dead at Chesterfield and District Royal Hospital following the fire at Williamthorpe Road, North Wingfield.
The 12-year-old's headteacher at North East Derbyshire Support Centre, Val Fisher, said: “Jordan had only been with us since September, but in that short time was making good progress.
"He was well liked by fellow pupils and staff and always had a big smile on his face. He enjoyed all the activities, and loved being part of a team. He was funny and sociable. We will all miss him.“
