Hi Celeste, 

Firstly I would do a session simply going through these basic skills and how to do them with the correct technique. You can find guidance on this in our fundamentals section.  

You can also find great passing drills in under 'passing' in our drills section. However here are a few I've selected that I think might help: 
1) The Clock - this will get your players to practice passing and moving 
2) 2 Lead Drive - this will allow your players to practice their longer passes, as well as highlight the importance of preliminary movement 
3) Chest Pass on the Move - this is a simple drill that will get your players driving onto the ball, whilst ensuring they abide by the footwork rule
4) The Star - this drill gets your players to practice passing off, clearing out (when going around the posts), to drive back in to re-offer for the ball 

These are only a few suggestions however there are plenty more to check out. 

Hope this helps.
