It's kind of a tough situation, but hey, if essentially you're coaching the 7th & 8th grade B team, then I think you should obviously be focused less on tactics, and more on exposure, as in finding the best ways to expose them to all aspects of soccer while making it fun. It's way more important for them to be working on small-scale fundamentals (trapping, passing, simple runs, balancing left and right sidedness, basic types of kicks) than it is for them to be doing dumb drills of goofy stepovers and side-volleys. I would be having them do lots of keep away type games, lots of spacing stuff, that sort of thing. Good luck, because they are going probably just going to want have penalty kick contests all day long, at least when they're not sitting around staring directly at the sun and eating grass.
google "coaching soccer" you'll get ten trillion ideas for drills and games there.

here are some good goals from the last time I saw a 2p2 good goals thread.
best of luck!
