Set up an area in the shape of a square with at least 12-15 spots place on the boarder evenly spread apart. Divide the class in half (2 groups) with one half standing on the spots and the other half stood in front of players on spots roughly 2-3metre apart depending on year level. Each player on the spot will need a netball each, these players will be named "passers" while those without the netball will be named "movers". The job for the "movers" is to recieve and make a pass with the player in front of them and then move away to another "passer" and repeat the process. The "mover" must NOT take the easy option of travelling around the square in a clockwise/anti-clockwise direction, instead they must travel across the square when finding a new "passer". Ensure that the "movers" are coming to a complete stop and standing in a balanced/stable position before passing instead of trying to pass on the move which in an actual game of Netball will result in travel/stepping.
Round 1 can be a practise - if there is enough time you can have a 2nd round where now the "movers" will compete with each other to see how many passes they can complete in the set time from the coach (1 or 2mins). The coach can tell them what pass they are to use (if both chest and bounce pass were covered at start of lesson).
Increase the amount of passers to make it harder for the receivers to find someone that is open. Change the type of pass the players must complete to alter the difficulty. Increase the playing area to make it more difficult to cover ground to receive a pass.
