My Classroom
This is our classroom. It is big. There are thirty tables and chairs for thestudents. There is also a desk for the teacher. A blackboard is in front of the class. The windows are on the right side of the room. We study subjects like Math, Bahasa Indonesia and Social Sciences in this room.
Sometimes, our teacher tells us to present our work or play games in the classroom.
