This is a music activity that my daughter learned in preschool, and now she applies it to any song that she knows. Two tunes that work well are "Head, Shoulders, Knees and Toes" and the traditional birthday song. Choose a consonant letter from the alphabet and use that sound to sing every word of the song. Example: B = Bed, Boulders, Bees and Boes or Z = Zappy Zirthday, Zoo Zoo! Our daughter gets such a kick out of this game that now we have advanced to blends such as bl, ch, etc. What a fun way to promote phonics and encourage reading readiness!
