Divide the players into two teams of equal number and name them 'Crows' and 'Cranes'. Draw two parallel lines one metre apart across the middle of the playing space, 10 to 12 metres away at either side, draw goal lines. Players line up, toeing the lines, the cranes on one side and the crows on the other side. The leader calls out in prolonged tone CR-R-R-R-R and ends as 'anes' (cranes) or 'rows' (crows). When cranes or crows whichever is called dash back to goal lines and are chased by the other group.
