What's your name?

A good way to practice things like 'Hello, my name is.... What's your name?', is to put a timer in a box. Everyone sits in a circle, and one person is given the box. That person says to the next person, "My name is X. What's your name?" and then hands the box to the person, the mini-conversation continues until the timer goes off. It's always funny to the see the face of the person when the timer goes off in their hand! Practice it first without the timer on, so everyone knows how to say it, then do it with the time for 2 minutes, then 1 minute. It gets them talking really fast!  You could have kids that have the timer when it goes off be out, but it might end in tears.
