In a statement, the school said Tiarnán had “an infectious personality” and was well known throughout the school as a “lorry fanatic”.
It announced that the school oratory would be open on Saturday and Sunday for pupils and their families to come together to remember Tiarnán.
“Following the return of pupils to school next week, the Education Authority’s Critical Incident Team, as well as school staff, will be available to help and support pupils at this very sad time,” the school added.
Jonesborough Primary School, which Tiarnán previously attended, said: “As a community we stand in compassion with Tiarnán’s family, understanding that words cannot soothe the heartbreak of loss nor grief, especially when a life ends so prematurely.
“Tiarnán was a lively and spirited boy, who will be fondly remembered by all.”
