Wth Sign Language for Everyone, both book and DVD's cover the essentials of American Sign Language—choose either or both. Two 2-hour DVD's teach over 600 signs of American Sign Language. This is the only introductory signing course that I know of that also teaches signs for witnessing. The signs are taught in groups with logical associations so that they are easily remembered.
The softcover book can be used to cover the same material without the DVD's or with the DVD's for review and practice. The course is appropriate for all ages.
