Person one has a container and on 'go' takes a scoop of water, carries it to the empty bucket and tips it in, then runs back and gives it to the next in line. The aim is to get as much water in the empty bucket as possible within a set time. Process is repeated. Hockey - using rolled up newspapers and a sock ball. Two teams, numbered off.
Umpire calls one number.
Others can be called on to help score a goal. Javelin - using straws. Obstacle Races - with tunnels, things to run around, climb through, etc. You can use equipment from the preschool to help set this up. Each player keeps going until he has put an 'egg' in his team's nest and then the next player takes over.
