A chalkboard is a flat surface, usually black or dark green, designed for writing or drawing with chalk. It is often used in classrooms and other learning or presentation spaces to display information or ideas to a group. The surface allows chalk to stick and can be wiped clean with a cloth or eraser, making it reusable. Chalkboards are typically mounted on walls or supported by stands, making them visible from a distance and convenient for teaching or communication purposes.
