Take the mystery out of writing Primary Triads with this fun approach. Steps given, plus self check quiz with answers, along with a key at the end that shows the circle of 5ths drawn as a line so students can check the key signatures for each assignment. This packet has been successfully used over and over with my students, who scored high on their state theory tests. My students are scale writing masterminds! Students write out the scale and are reminded of the importance of double checking their work along the way as they build their I-IV and V chords. Additional information is given, and students are challenged to step up to the plate and become Theory Masterminds. Have fun with this packet. My students do!
