Discussion with Large Groups

We have the happy problem of having too many kids. It makes 
discussions virtually impossible, but other than Wink and Capture 
the Flag, it's what the majority of youth in our group want on a 
Sunday evening.
Here's one technique that would work well with any number of kids though, and it's a nice change from the circle or fishbowl. Have each youth write down a controversial situation. This could be 
anything from the Iraq war, to having a friend who makes racist or 
homophobic comments, to being in a situation where alcohol or drugs 
are being used.
Put a long piece of masking down across the floor of your room, and label one end AGREE/APPROVE and the other DISAGREE/DISAPPROVE.  
Have youth exchange papers with one another, and ask for 2 volunteers.
Have the first volunteer read what is on his paper. Ask the second
volunteer to take a stand on the tape line which represents how she feels about the situation. She should explain why she chose the position on the line which she did.
At that point, the rest of the group is invited to give arguments (pro/con) or make comments about the situation in an attempt to change the mind of the person standing on the tape line, who will move and respond to comments from the individuals in the group if she feels so inclined.
Continue until it's boring, then choose two more volunteers.
This isn't only an interesting way to create a vibrant discussion, it's also a good chance for youth to see peer pressure at work, to find out what "moves them", to see the influence they have on others, and so on.
 

Another great site for resources

Here it is, more different ideas that are easy to lead.  Search for ideas by exercise or outcome.  Everything I've used from here has been great!

Searchable database of activities, exercises, and games

Searchable by keyword, type of tool (icebreaker, simulation exercise, etc.), or topic, this website has a bunch of great and different activities for your meetings! Enjoy.

Everything Old is New Again

Some of the exercises I love the most only work one time with any
one group.  Once you do them, the secret is out, and you can't use
them again for, oh, four years or so, until the new generation comes through the doors and all your old stuff is new again.
Over the years, I've discovered many ways to reuse and recycle
great games and meetings, making them more challenging and
different and thus useful at least every two years, if not every year. One favorite of mine and our group is the Broken Squares Exercise.

Play it once with your group - it's a great one - but if you want to
play it again, try this small change: eliminate one person per group, and eliminate one square.  The trick? tell the group they still have to create 5 squares.  The answer: they will need to build 4 individual squares which together create one larger, 5th square.

For the youth who think they know this game, it becomes extra tricky as they are forced to think outside the box (square!). Some will insist you did it wrong; others will figure it out eventually.  Change your follow-up questions to suit your particular group situation, or have them create their own questions based on their 
experiences.
