I feel that protecting the environment is very necessary, because it brings health to everyone, so my class chose the job of cleaning the classroom. On Friday afternoon my class started. In order to work well in the class, I have prepared masks, rags, brooms .... The teacher assigned tasks to each team, each of you in great detail. The boys are strong, so the teacher assigns the task of setting up tables and chairs, sweeping spider webs. As for the girls, they do the job of picking up trash and cleaning boards. I was assigned by the teacher to clean the board. First, I crumpled the towel and then went back to class to clean the board. I wiped it clean from board to board to get her complimented. The working session was very tiring but it was so fun, I looked at all of my friends' faces all turned red and sweaty. When the principal entered my class, she was very pleased to make the head teacher very happy, so everyone in my class got a bonus. Less than an hour my class was finished. I am very proud of my class.
