Nets of a Cube - Geometry Manipulative Set

myminifactory

Which of the following nets might be folded into a cube? The question above demands that students mentally convert a 2D outline into a 3D object. While many students can instinctively answer this question, others struggle especially in high-stakes standardized testing environments. The Nets of a Cube - Geometry Manipulative Set allows students to explore the connection between a 2D outline and a real 3D object. Students fold/unfold the manipulative between a flat object and a cube. Once students make the connection, they are able to 'see' the relationship like an optical illusion. This math manipulative was designed based on the need of a high school geometry teacher to provide a tactile learning experience for exploring 3D figures. The set contains six nets, three of which form a cube and three that do not. The set allows teachers to create physical problem sets in various formats that emulate standardized test questions. Which of the following nets might be folded into a cube? (Four answer multiple choice - one correct answer) Which of the following nets cannot be folded into a cube? (Four answer multiple choice - one correct answer) These foldable cubes can be used for a variety of lesson objectives, including math vocabulary, properties of a platonic solid, 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. The design has been printed successfully by the designer in PLA/ABS on multiple machines, including a Makerbot Replicator 2X. Variation of the design has been printed in the wild. See instructions for printing tips. Educational Value: The design is based directly on the stated needs of geometry and elementary math teachers. Manipulative has seen classroom use with students and balances content area appropriateness with fun. It's 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 and show how very basic shapes can create more complex structures. Visit my blog at http://www.designmaketeach.com for more 3D printing lesson ideas.
