This game teaches kids the value of communication and trust.
It works best if you have a large area, indoor or outdoor. Setup a series of obstacles (chairs, tables, balls, etc).
Ask the group to pair off - one person is blind folded and must make their way through the 'mine field' by listening to their partner. Their partner verbally talks them through but cannot enter the mine field. If the person hits a 'mine' they must return to the start. After everyone has gone through, swap roles.
At the end of the game, talk about what they learnt about communication and trust.
