The blackboard is a three-dimensional object that is typically rectangular in shape and consists of a flat, smooth surface made of a dark-colored material, usually black or dark green. It is commonly mounted on a wall or supported by a stand and is used for writing or drawing with white or colored chalk. The edges of the blackboard are usually framed with a wooden or metal border to provide structure and protection. One side of the blackboard is the writing surface, which can be easily erased and updated. It may also feature a small tray or ledge at the bottom to hold chalk, erasers, or other writing tools.
