New here so sorry if wrong forum - Help re boredom

[Lee]

I am a coach of U12 side & we have a large gathering on a Saturday morning. We have at least 20 players every week ranging from the complete useless to the top grade eye openers. What Im finding hard is keeping them all involved all the time. We have a 2 hour outdoor session.

I have devised a few of my own little games which involve splitting the kids into two teams & competing against each other, this is fine & fun, however, after 10 minutes of this, the kids get bored. I get them doing passing & heading drills etc.. but this is hard to keep track of as there are so many kids & no willing parents with football knowledge available to help. So, 10-15mins warm up, 10mins game, 10mins skills & then they & me, are a little stumped so we end up playing a match for the next hour.

can any1 advise some mass games that every1 can get involved in

I know it would be easier for me to train only the team & not the few joiners on, but in the joiners on in the summer, we signed up a new lad who was so good, Chelsea scout watched him bang in a hat-trick from midfield last Sunday, mind u, we won 10-1 so I dont want to turn any1 away as a diamond can be found sometimes
