More than 600 district students joined hundreds of schools around the world as they participated in the 10th annual World Sport Stacking Association Stack Up Day on Nov. 12.

Organized by members of the physical education departments in each of the buildings, students signed up to take part in the event, which included 30 minutes of stacking in an attempt to set the new Guinness World Record for speed stacking cups.

Students stacked cups of all sizes in various assigned pyramids, went head to head against the clock to beat their fastest time, competed in relays and participated in a variety of fitness-related activities.
