ABSTRACT:
An educational aid is provided which is adapted for classroom control and instructional use. The aid comprises a generally rectangular flat support panel, and a pocket mounted at one end of the support panel and having an opening which faces the other end. Three discs, which are respectively colored red, yellow and green, are adapted to be magnetically secured to that portion of the panel to simulate a traffic light, and any of the discs which are in non-use may be retained in the pocket. The aid is adapted for classroom control of young students by permitting various discs to be displayed to indicate permissible or non-permissible activities. Also, the aid may be used to instruct the students as to the meaning of the various signals of a conventional traffic light.
