What is one alternative term for a blackboard that is often used?

The term "greenboard" is often used as an alternative to "blackboard" because it refers to a similar surface used for writing and drawing, typically in educational settings. Just like a blackboard, a greenboard is designed for use with chalk, but it has a green hue that some educators prefer for its softer appearance. This type of board serves the same functional purpose as a traditional blackboard, allowing instructors to present information to students in a visual manner.

In contrast, corkboard is typically used for pinning notes or visual materials rather than writing directly on it, making it unsuitable as a direct alternative to blackboards. A flip chart is designed for use with paper on which information can be written and flipped, which is a different medium altogether. An interactive board combines digital and traditional educational tools but does not refer to a simple writing surface like a blackboard or greenboard.
