The keen rugby union fan scrummed down with pupils in a mini-tournament at Eccles RFC in Salford, Greater Manchester.
Harry, 30, certainly seemed to enjoy himself on the pitch – running around passing and catching the ball and shouting encouragement to kids playing touch rugby.
Prince Harry is patron of England Rugby's All Schools Programme, developed by England Rugby to increase the amount of rugby played in state secondary schools, and to encourage new players to join local clubs.
Harry arrived at the rugby club ready for action, rigged out in trainers, black waterproof jogging bottoms and a casual England rugby T-shirt.
He also met with student volunteers before helping them run a rugby festival for other younger children from the local area.
The All Schools Programme is a project launched ahead of next year's Rugby World Cup, hosted by England. The Programme supports state secondary schools over three years with kit and equipment, coaching, student volunteer training and links to a local club, to help them start and sustain playing rugby union.
It aims to have 750 more self-sufficient rugby-playing schools by the time of the next Rugby World Cup in 2019 in Japan.
Prince Harry is honorary president of England Rugby 2015, the organising committee delivering the Rugby World Cup 2015. He is also vice patron of the Rugby Football Union and patron of the RFU Injured Players Foundation.
Prince Harry learned yesterday (Monday) that he will become an uncle for the second time in April.
