Grab the Wheel . . .
was developed as a quick and easy way to practice speech sounds. The wheels can be used in therapy or as a home practice material. This set of wheels targets the production of the /s/ phoneme in the initial position of words. The target words were chosen from high frequency word lists. There are two low density wheels and two high density wheels.
(You may want to visit Caroline Bowen's site for more information on target selection for intervention for more information on density.)
