In this case it means Our Really Exciting Online Project, but it does use the scrumptious cookies.
Classrooms are invited to participate. Each classroom will need to have each student stack Oreo® cookies as high as he or she can and then average all their individual results to achieve a final class result. I can foresee a lot of math in this project and maybe some "cookie faces" as well.
If you want to participate or learn more about the O.R.E.O. Project, don't delay. The project begins on September 19.
(Be sure to read the Oreo® Trivia.)
