Last week, Mr Tan, the form teacher, told his class that they would be doing spring-cleaning. The children were very excited.
Jack and Peter mopped the floor. Jack was so engrossed in cleaning the floor that he did know realise that he had kicked the pail of water. Peter was did not see the puddle of water on the floor behind him. As he stepped backwards while mopping the floor, he slipped and fell. Fortunately, he was not seriously injured.
Other than this incident, everything went on smoothly. The windows and the whiteboard were cleaned.
Mr Tan was pleased that all the pupils played their part in cleaning up the classroom. He thanked them.
