We are using sign language to learn the names and sounds of each letter of the alphabet. It is very motivating to the children and if they practice regularly, they will quickly know all of their letters/sounds. This is the beginning of learning to read. Here is a link to several videos which will help your student practice. We use these videos in the classroom, along with the CD and book shown.
