Nets of a Cube - Geometry Manipulative Set

Which Nets Can Be Folded to Form a Cube? Many Students Struggle to Convert a 2D Outline into a 3D Object. The question challenges students to think creatively and make connections between flat shapes and three-dimensional objects. While some students can intuitively answer this question, many struggle in high-pressure testing environments. To help teachers provide a tactile learning experience for exploring 3D figures, the Nets of a Cube - Geometry Manipulative Set was designed. This set allows students to explore the connection between a 2D outline and a real 3D object by folding/unfolding the manipulative between a flat object and a cube. Once students make this connection, they can "see" the relationship like an optical illusion. The math manipulative was created based on the need of a high school geometry teacher to provide a hands-on experience for exploring 3D figures. The set contains six nets, three of which form a cube and three that do not form a cube. This allows teachers to create physical problem sets in various formats that mimic standardized test questions. Which of the following Nets Can Be Folded to Form a Cube? (4 answer multiple choice - 1 correct answer) Students can use these foldable cubes for a variety of lesson objectives, including math vocabulary, properties of platonic solids, measurement, calculation of area and volume, and percent error calculations. A PDF of lesson ideas for the foldable nets of a cube is included in the downloads. Printability: Designed for a 0.2 mm layer height, this design has been successfully printed by the designer on multiple machines using PLA/ABS. Educational Value: The design is based directly on the needs of geometry and elementary math teachers. This manipulative has seen classroom use with students and balances content area appropriateness with fun. It is easier for students to manipulate than paper-based alternatives. Creativity: The print flat design explores the flexibility of the print material to create a moving hinge that is foldable and appeals to students. The designs were created in Tinkercad, showcasing how basic shapes can create more complex structures. Visit my blog at http://www.designmaketeach.com for more 3D printing lesson ideas.

Only three of the designs can be folded into cubes (Netcubea.stl, netcubeb.stl, and netcubec.stl). Can be printed with or without infill. Examples were printed with PLA. Designed for a 0.2 mm layer height. Note: The print must be oriented on the build platform so that the infill lines are as perpendicular as possible to the folds. If the infill lines are parallel to the folds, the folds will crack. We've had success rotating the print to approximately 30 degrees. Design requires tape or glue to hold the shape of a cube.
