The supplement and ditto packet to the fine arts strand of unit nine for third graders contains illustrations, ditto masters, and four songbooks to help the teacher carry out the fine arts activities of this unit. Materials for both group activities and seatwork are included. Kit 33 uses the songbook "Canciones de Aqui y de Alla" and studies the relation existing between sound and their symbols, and the timbre of string instruments. Kit 34's book "Cantando a Dos Voces" teaches the skills of two-part singing. The songbook "Escucho y Canto" of Kit 35 extends the child's dance experiences, and "Sonidos y Melodias" of Kit 36 helps the child identify the expressive qualities of music. Supplement illustrations include pictures of musical instruments and scenes from songs as well as visuals for music theory. The ditto packet contains written exercises in music theory in addition to matching and fill-in-the-blank type activities. All materials supplied to the students for classroom use are presented in Spanish, with brief introductions to the packet in Spanish and English. The brightly illustrated songbooks feature music, words, and guitar chord positions. (DS)
