FUTURE engineers and architects at a Gourock school have honed their skills with a series of den building sessions.
The P7 classes at St Ninian's Primary came up with their own creations made from pieces of wood, crates, hula hoops and plastic cones.
The object of the exercise was to boost their team-building skills and bring what they learn in the classroom outside.
School head Lesley McCabe said: "Through loose parts play like this the pupils develop communication, team-building and leadership skills as well as resilience and problem solving.
"The children have been busy creating different structures with the loose parts, which involves negotiating and perseverance."
