Start from inside the
classroom and turn left as
you leave the door (going
outside). Walk for about 30
yards. You will see a wire
fence in front of you. Turn
left and walk for about 60
yards. The playground will
be on your left.
Go outside and head
East for 58 steps.
Then go North and
walk for about 100
steps. You will
probably see a lot of
children. Ask one of
them where to go.
