One of the major events in yearbook photography is the big dance of the year. It can be the high school prom, the college formal, or even a military social (I've edited and shot for high school, college and military yearbooks over the years). In each case it's important to understand that photographing such events calls for capturing images that do more than just show people.
Formal dress is expensive, flashy and colorful and makes for great images. It's important to capture the gowns, tuxedos and uniforms and show the wearer's pride in their outfits. In some areas (Southern New Jersey, for instance) the custom is for the high school girls to give an impromptu fashion show for parents and friends outside the venue. Be prepared to get some images of them strutting for their audience. Wide angle lenses can capture the dress and the crowd, just make sure your primary subject is close to the camera so she dominates the frame.
Speaking of showing off, don't forget that participants often rent limousines (either singularly or by pitching in). Make sure to capture some images of the attendees as they exit the limo (use flash and a wide angle zoom lens).
On the dance floor look for tight shots of couples slow dancing together along with wide shots of the crowded dance floor. If spotlights are being used, look to backlight a dancer or couple for an interesting silhouette.
Don't forget to grab some table shots too. Have the half of the table with their backs to the camera move to the other side so they're in the picture too (either pose them standing behind the seated couples, or arrange it so women are seated and men are standing).
