Classroom Pocket Charts are used by teachers in schools everywhere.  Most Pocket Charts are made from nylon with clear pockets.  Some have extrawide pockets that can easily hold a sentence strip plus a picture for use in many subject areas. A small wooden dowel in the rigid bottom and fivegrommet top, keeps the chart straight. Use them for a variety of things in the classroom including Calendars, Job Assignments, Sentence Structure, Sequencing, Vocabulary, and other General Classroom Activities.  Check out Sites For Teachers for more info on pocket charts.
