Red Light Green Light is an outdoor game suitable for children of all ages. You will need quite a bit of space! If you play the game with younger kids, you can use it to reinforce the concept of "red is for stop" and "green is for go".
One player (or an adult) is chosen to be the caller. The caller stands facing away from the other children, who stand behind a starting line drawn up about 30 feet (10 metres) away.
When the caller calls out "green light", the children run forward to try to tag him. They must move as quickly as possible but at any time the caller may call out "red light", at which point all the children must freeze. The caller turns round and if he catches anyone moving - even a tiny bit - they are sent back to the starting line.
The first player to tag the caller becomes caller in the next round.
This game is very similar to What's The Time Mr Wolf.
