Set up a number of gateways in a defined playing area by placing two cones of the same colour about a metre apart. In pairs players will start either side of the gateway with a hockey stick each and one ball. The first person completes a PUSH pass to their partner through the gateway. Their partner will then TRAP the ball and complete a push pass back to their partner. When 5 push passes and traps are complete, the player with the ball dribbles to another gateway.

Before starting the game, demonstrate to the students how a push pass is executed with correct technique. Hockey stick always remains in contact with the ball throughout the entirety of the shot - should not hear a loud clapping noise from the hockey stick + ball making contact. 
To trap correctly talk about the hockey ball and the colours. When the hockey ball is moving along the ground all the colours merge forming a rainbow, when the ball is trapped (completely stationary) you can now visibly see all colours individually without them merged toegther like a rainbow. 

NOTE: if there is enough time the coach can add in a competition between all pairs within the class to see who can complete passes at as many GATEWAYS as possible in the allotted time.
