Okay, so I've seen all the posts about word walls on this website and I've even tried word walls in my classroom the last two years, but I always end up taking it down. Can anyone explain in layman's terms what a word wall is, when it is used, why I should use it and how to do it. I guess I need word walls for dummies... Thanks in advance. I really want to use a word wall with my third graders, but am having difficulties grasping the idea.
