SIGNING Basics' instructors help their students learn to speak without uttering a word. Through private lessons and group classes, they teach American Sign Language to students of all ages and backgrounds. Introductory lessons lead students through the basics of the sign-language alphabet and movements. Advanced classes show students how to carry conversations, enabling them to communicate effectively or correct baseball coaches' faulty ?charge the mound? gestures. Instructors also offer workshops that impart basic techniques for businesses and groups.
