Inspired by the video Caine's Arcade, in which a young boy creates an entire arcade out of cardboard, the Cardboard Challenge has become a beloved 5th grade tradition at Proctor Elementary School. Students work in groups to build something out of cardboard in the CLIC lab. Then on the day before Thanksgiving their cardboard creations are put on display for the school staff and students to enjoy. Every year students unleash their imaginations and problem solving skills to create a fun-filled event.
