Select 6 players who may kick during a game. Set up the area in between the 10m line and the try line. Separate the area into two halves and have three players line up on the try line and 3 players on the 10m line. The aim of the drill is to have the players kick the ball so that it lands before and bounces over the opposing teams line. Players can move anywhere in their half and the key part to highlight is the importance of kicking into space and finding the gaps between the players. 

Create punishments for the ball being caught by the opposing team and being dropped. 

More talking points could be working on the positional play of the back 3 in defence. 

Hope this helped.
