The project, which is part of an ongoing Cross Community programme between the two primary schools, was designed to use sport to bring pupils from the two schools together.
Rory and the Principal of Knockloughrim Primary School, Keith Elliot, took the 45 girls and boys from the two schools for an hour-long session where they practiced basic skills.
All the pupils were given the chance to speak with Rory and he kindly signed their Ulster and Ireland shirts, and even just their school bags! Samuel Hawe, who is in the P7 class at Knockloughrim Primary School, dubbed it "the best day ever at school."
Knockloughrim Principal Keith Elliot said: "It was just fantastic to see Rory visiting our school and meeting all the pupils from St. Brigid's too. We really appreciate the support from Rory and Ulster Rugby."
The Cross Community programme has seen the two schools participating in various outward-bound activity days and this latest joint venture was viewed as the highlight so far.
