I like to use a magnetic dart board for a visual while working on the /r/ sound in speech therapy. I tape an /r/ to the center of the dart board and explain that a perfect /r/ sound is a bullseye. The old sound (Check out old sound/new sound here) is like hitting the dart board on the outer most edge. A distorted /r/ can land anywhere in between. As the child produces /r/ words/syllables, I show them how close they were to a bullseye. I also use this activity for auditory discrimination. The child listens to my /r/ and shows me how close I came to getting a bullseye. Don't have a dart board? A picture works just as well! I hope you enjoy this mid-week quickie!
Talk it up!
