The Saints director of rugby - along with players Alex and Ethan Waller - took advantage of the spring sunshine to lead a session of the Aviva Premiership Rugby Schools Programme at the school, situated in Northampton's eastern districts.
Mallinder commented that it was vital for clubs at the elite end of sport - such as Northampton Saints - to use their position to inspire youngsters into participating and enjoying their rugby.
"We're playing at the elite end of sport, but it's not all about that," he said. "We need to get out and to encourage people to participate. Playing is really important, whether that's in rugby or in sport in general, and then if we can get them to have an interest in rugby as well then we're achieving our goals.
"The Saints is a fantastic club in the community. At the club we get a lot of children coming in, especially from primary schools, but it's also important that we get out into some of the schools as well. It's great for them to see the community coaches and the players as well."
The Aviva Premiership Rugby Schools Programme is currently in its third season. The Programme, which comes with a £2million investment from Aviva, is an initiative which introduces more than 39,000 young people each season to rugby union through tag rugby, creating a vibrant and effective rugby legacy in England.
The scheme targets non-traditional rugby schools and provides five weeks of coaching and teacher training, grassroots club links, plus resources for the school to continue to play rugby in the future.
