My students love doing these warm-ups because they can hear the relevance to songs heard from the Pitch Perfect movies and Just Dance video games. The sight-singing is also lots of fun because they can see patterns which come up in their favorite songs. Also, clapping the rhythms is another possible activity, because I included the note stems. Attached is a PowerPoint with sight-singing slides that correspond to each of the seven songs unlabeled so that the student can sight-read then hear on the next slide if they got it right. Higher levels can do some analysis on some of these tunes using the scale degrees depicted on each slide.
