Unit 10 of a fine arts bilingual program developed for the third grade is oriented toward the basic theme of communities around the world and supports the spiraling questions of who the individual is, what his alternatives are, how he can initiate change, and what the results of change are. This teacher's guide to kits 37-40 explains focus, objective, and materials for each of the learning activities in English and Spanish; teacher instructions are in Spanish. Kit content includes recognition of the timbre of the harpsichord, binary form of a musical selection, changes in musical dynamics, rhythm, interpretations of song with original dramatizations, rhythmic game, major and minor modes, percussion instruments, Mexican dance, part-singing canon, rhythmic experiences, harmony, note positions, original dramatizations of a song and musical selection, biographic studies about Robert Schumann, harmony singing, expressive qualities of music, musical story ("The Singers of Bremen"), review of note values through rhythmic game, clapping, and rhythmic movements. Unit 10 also includes a recording of vocal and instrumental selections on cassette (available separately from the Dissemination Center). Each kit has assessment activities. (RS)
