I feel that environmental protection is essential, because it brings health to everyone, so my class chose to clean the classroom. On Friday afternoon my class started. In order to do a good job, my class prepared masks, rags, brooms .... The teacher assigned each team, each of them was very detailed. The boys are healthy so the teacher tasked with setting up tables and chairs, scanning spider webs. And the girls do the scavenging work, wipe the board. I was assigned by the teacher to wipe the board. First I went to the towel and went back to class to wipe the board. I wipe the board from table to table so I can clean it up. The labor was very tired but it was so fun, I looked at your face all red, sweaty. When the principal entered her class, she was very praised as a very happy homeroom teacher, so each class was rewarded with points. Less than an hour my class was done. I am very proud of my class.
