Pecan Grove Primary students in kindergarten through second grade participated in the Stack Up day Nov. 13.

More than 2,000 schools in 35 countries participate in cup stacking to try and break the Guinness World Record of the most people stacking at multiple locations in one day. The goal for this year was 600,000 stackers. Pecan Grove students practice their styles of cup stacking and battled one another with speed stacking. The students also created new versions of stacking.
