These charts come in handy to help others find your class if you aren't in the classroom. Includes one header and 8 locations
Place the "Where Are We?" header chart hanging near your doorway. You can post all of the locations and use a clip to indicate where you are in the building. Or, what I prefer to do, is only clip the single location under the header and keep the rest put up until they need changed.
Also, one of my student helpers is in charge of changing the location. They enjoy this, and frankly, remember better than I do.
