Say what you can see when you come into the classroom

When I come into the classroom I can see a big blackboard on the wall. Also I can see twenty desks and a teacher's table. In addition, there are many shelves with books and copybooks and a couple of posters above the blackboard. Behind the blackboard I can see a small cloakroom for coats and jackets. The room is very light because of three big windows. Finally, there are many blossoming flowers on the windowsills.
