How can I develop some concrete way to let the child know that he has completed a particular activity rather than my just signing FINISHED?
Often children who are blind and nonverbal may not know how long an activity will last or understand our expectations for a particular task. They may be quite startled by a sign for FINISH that seems to come out of nowhere. It is important to make the message and expectation very concrete and easy to understand. One simple way is to tell the child how many times he or she is expected to do a task and make that expectation apparent from the materials that are available. For example, in a block and container play activity, put out 5 blocks for the child and say use key tactile signs PUT BLOCKS IN BUCKET, 1,2,3,4,5, FINISH. Similarly, at clean up time, you can specify how many things and the names of the things that the child needs to locate and put away. This is helpful if the child cannot see whether or not the whole area is cleaned up. For example, Jimmy, find the car and the hat and put them away. You can let children know when there is Five more minutes of playtime. Introduction to n
