Blackboard - Uses

Uses

Blackboards are often used in teaching, although in wealthier countries their use has diminished. University lecture theatres may contain a number of blackboards in a grid arrangement, with each column mounted on rollers to allow the lecturer to move boards into reach for writing and then move them out of reach, allowing a large amount of material to be shown simultaneously. Blackboards are also used in many establishments (typically public houses) as a form of advertising often for upcoming events and menus and to record the score in darts matches. They are also used in homes, specifically in the kitchen, for writing messages, shopping lists and things to remember, as well as sometimes serving a decorative purpose.
