Cardboard Sculpture & Engineering | 3D Art and STEM Projects for Grades K–12

Bring sculpture, creativity, and engineering into your art room with this comprehensive 100-page Cardboard Sculpture & Engineering resource for grades K–12. Students learn essential cardboard construction techniques before applying those skills to engaging three-dimensional design challenges. Projects progress from playful elementary builds to more advanced middle and high school sculpture, architecture, functional design, installation, and sustainability challenges. Use the complete resource as a sculpture or STEAM unit, choose projects by grade level, or assign individual challenges for makerspaces, early finishers, enrichment, sub plans, or independent work.

Estimated Time Flexible — individual challenges may take one class period or several class periods depending on grade level, complexity, and project choice. Teacher Tip Teach the construction techniques before beginning the larger design challenges. Giving students practice with tabs, slots, braces, scoring, folding, layering, and reinforcement first will make the later projects much more successful.
