The 'All Schools Programme' was launched last year with the aim of showing rugby union is a game that everybody can play and that it is not just for elite schools - like Eton College where Prince Harry went.
More than 100 secondary schools joined the project in 2012/13, and 100 more have signed up for 2013/14. Overall, the RFU hopes 750 schools will benefit from the scheme.
Speaking at Twickenham, Prince Harry said: "There are so many good things about rugby. You've got to make rugby cool. I bet you can if you get your proper kit and put that up at school, you'll get more kids wanting to play."
Prince Harry is taking a coaching session for youngsters at Twickenham Stadium. Harry, who is patron of the Rugby Football Union All Schools Programme, is meeting schoolchildren to try and increase the number of pupils playing rugby in state schools.

The London Welsh rugby union team will find out next week whether their appeal against a five-point deduction and £15,000 fine has been successful.
An appeal hearing took place yesterday, over their punishment for fielding an ineligible player - New Zealander Tyson Keats - in 10 Premiership games.
Keats should have been eligible for an ancestry visa, due to his grandfather being born in England, but Mike Scott the former London Welsh team manager made a mistake in the original application.
Instead of reapplying, Scott told Keats' agent and the club that the visa had been successfully granted to the player. Meanwhile, Scott submitted false documents - including a forged passport - to the RFU in a bid to pass Keats off as English-qualified.
Scott has since been banned from rugby for life and cautioned by police for falsifying registration documents.
London Welsh argued they should not be blamed for fraudulent behaviour conducted by Scott, who was described in the original judgement as a "rogue employee".
The points deduction sent London Welsh bottom of the Premiership, two points behind Sale Sharks with five games left.
Braving rain and an extremely muddy pitch, the Prime Minister - who said he used to play the position of hooker - passed a rugby ball around with children who were having a taster session at Millwall Rugby Club in east London.
