One of our favorite games in music class is Jericho Jenga. Students sit in a circle with a jenga stack in the middle. One student walks the circle (to the beat) as everyone sings the first half of Joshua Fought the Battle of Jericho. At "the walls came a tumblin' down" the students tops in front of someone in the circle ad that person goes to pull out a jenga block while the class sings the second half! Repeat (over and over). For big classes use two Jenga stacks and two people walking.
