Revolving boards, also known as rotating boards or turntables, are writing surfaces that can be rotated or flipped over to reveal a new writing surface. They are commonly used in classrooms and meeting rooms where space is limited, as they provide multiple writing surfaces without taking up additional space. Revolving boards can be mounted on a stand or hung from a wall, and are available in a variety of sizes and configurations. They are useful for facilitating group work, brainstorming sessions, and presentations. Revolving boards are also a cost-effective and eco-friendly alternative to using multiple single-sided boards or pads of paper. Overall, revolving boards are an efficient and versatile tool for collaborative learning and communication.
