The booklet contains illustrations of 100 basic signs for use by school employees in working with the deaf. The signs were chosen for inclusion in the booklet by a committee which reviewed hundreds of signs and evaluated their importance in communicating with the deaf. The illustrations, taken in large part from the "Preferred Signs for Instructional Purposes" text, appear with the English and Spanish word equivalents. The signs are broken down into three categories - safety signs such as stop, go, wait, cold, and hospital; informative signs such as where, boy, mother, teacher, after, and month; and courtesy signs such as good morning, hi, sorry, and excuse me. A brief explanation of the markings appearing in the booklet and the manual alphabet are also included. (PHR)
