Hi Hema,
Sorry for the late reply. One game that I've used in my communication skills programs is the rope game. Its very useful as an energizer as well. It goes like this:
Materials needed: One rope around 20 feet long depending on the size of the group.
Directions:
Ask the participants to stand roughly in a circle and to close their eyes. its very important that they keep their eyes closed throughout the game, so do take their commitment.
Then quietly enter the circle and put the rope in the centre. spread it around so that its roughly in the shape of the participant circle, not coiled up and not crossed.
Tell the participants that if they bend down and grope a bit they will come across an object (do not tell them its a rope), and that they are to keep a hold of it all througout the game.
Once all the pax are holding on to the rope, ask them to work together and form a square with the rope - meaning that they are to stand in the form of a square holding on to the rope.
If you want to make it bit tougher, ask them to make a hexagon or a polygon etc.
Give them 15 minutes to work on it.
Analysis questions:
Were you able to accomplish the goal? if not what were the barriers to accomplishment?
What sort of communication mishaps occured?
Was there any emergent leadership?
What needed to happen for the goal to be accomplished?
Hope that helped. Best of luck with your program.
Regards
