Each set contains words with a target sound in various word positions (beginning, middle, and end). Most decks contain 40 articulation cards per sound, though some have fewer words if they are not extremely common in the English language. Each set also contains worksheets for home practice. There are worksheets targeting each sound in each word position. The worksheets include instructions and simple check boxes for telling families how to practice the words (imitation or spontaneous, word/phrase/sentence level).
