Children playing on the play ground.
Swings going back and forth.
See saws going up and down.
Merry go rounds going around and around.
Children running everywhere.
Now no children on the play ground.
No swings going back and forth.
No see saw going up and down.
The merry go round has stopped.
No children running .
Where have all the children gone?
Back to class. School is going on.
