A wor wall is literacy tool composed of an organized collection of words which are displayed in large visible letters on a wall, bulletin board, or other display surface, usually in a classroom. The word wall is designed to be a tool for students or others to use, not just a display, and contains a list of words that can be used during writing and/or reading to reinforce vocabulary. Word walls can be used by individuals or as a tool for cooperative learning and can be used to learn vocabulary for many subjects.
