I'm a little rusty with my public speaking but I know pretty much what I want to say. I I explain what the activity is about and what they have to do. Off they go and they begin working on the task. The task is not all that difficult; just shuffle cards around on the desktop and pick and choose what to use and what to negate. There's no right or wrong. I get a question or two mid-stream but the task is pretty much self-explanatory.
