A green board is a traditional teaching and presentation tool with a dark green writing surface commonly found in classrooms and meeting rooms. Designed for use with chalk, the board provides a smooth, reusable surface that allows for clear writing and easy erasing, making it ideal for explanations, diagrams, and problem-solving. Its green color reduces glare and eye strain, offering better contrast than the older blackboards. Green boards are typically made from materials like steel or a coated wood composite, framed for durability, and often mounted on walls or installed on stands. They are available in various sizes to suit different spaces. Easy to clean and maintain, green boards remain a popular choice for educational and professional settings, supporting interactive learning and communication in a traditional yet effective way.
