The primary use of green boards is for teachers to write or draw concepts, problems, and examples to illustrate their lessons visually Green boards can be used as a tool for interactive learning, where students can come up to the board and write or draw their ideas, or solve problems in front of the class Green boards can be used for brainstorming sessions where students can share their ideas and suggestions Teachers can use green boards to highlight the key points of their lessons and help students understand complex concepts by visually organizing information Writing on a green board reduces the need for handouts or printed materials, which helps to save paper and reduce the school's carbon footprint
