All classrooms have walls, of course, and how you fill or use them can affect the mood or feeling of a classroom. More displays make the room more interesting and be used to reinforce curriculum goals and display (and hence recognize) students’ work. But too many displays can also make a room seem “busy” or distracting as well as physically smaller; and they can also be more work to maintain. If you are starting a new school year, then, there is usually a need to decorate some of the wall or bulletin board space, but no urgent need to fill it all. Leaving some open space can give flexibility to respond to curriculum or learning needs that emerge after the year is underway. The same advice applies for displays that are especially high maintenance, such as aquariums, pets, and plants. These can serve wonderfully as learning aids, but do not have to be in place on the first day of school. Not only the students, but also you yourself, may already have enough distractions to cope with at that time
