There are a number of fun ways to develop great communication skills through various public speaking games. There are many aspects to being an effective and confident public speaker, and there are games that can be utilized for each aspect.
The three components to a speech are the content of the speech, the verbal communication, and the non-verbal communication. Each of these requires a different skill set, and therefore a different style of learning game is required also.
The non-verbal communication aspect of public speaking is very important. In ways, much more important than the verbal. It is also an easy one to begin learning through games.
One of the most effective ways of learning to enhance your non-verbal skill set is though pantomime.
For this exercise I invite the learners to think of an activity they would like to see acted out. I ask them to make it somewhat challenging (taking a walk or chopping down a tree can be too easily diagnosed in a few seconds).
As an example, building an igloo would be more challenging to act out and interpret than building a snowman.
I give them a few minutes to consider this. I then ask them to write their ideas down and place them into a hat.
The participants are then called up one by one and reach into the hat to select an activity (should they pick their suggestion they are asked to exchange it for a different one).
From there it's basically a public speaking game of charade's. The "speaker" non-verbally acts out the activity in a manner that gets the message across to the audience.
This broadens and extends your gestures, and also calls on you to enhance your facial expressions. These are important and powerful skills to incorporate in the arena of public speaking. They increase the effectiveness of your entire presentation.
