We have a new classroom. It's very big and yellow. In our classroom, you can see a teacher's desk. It's in front of the blackboard. It's orange. The computer is on the teacher's desk. It's white. You can see a picture on the wall. It's beautiful. My desk is clean. It's near the window. Amy's desk is near the door. A black and white bag is in it.
