Go round the room with introductions (name, age, reason for attending course, etc.)and three unusual things about you, but make one of them a lie. When everyone has finished their introduction go round again and people can guess which was the lie for each person.
Useful on lots of levels, it starts open interaction, makes people laugh, gives something for people to talk about during coffee break, and breaks down those first impression conclusions we all jump too.
It's quite fun to find out unusual things about people, and it's interesting to find out what people will lie about :lol:
As course leader, brush up on your body language reading skills and test yourself to see if you can spot the lies too from reading their signals
Oh and start the icebreaker yourself, it's always best to lead by example and make your lie really outrageous so others will follow and think wild stuff!!
