Lesson Plan: Extensions and Real-World Applications of Nets and 3D Shapes

This engaging lesson explores advanced applications of 3D nets and their real-world connections in engineering, architecture, and packaging design. Students will investigate Euler’s Formula to understand the relationships between vertices, edges, and faces of polyhedra. They will also examine how geometric transformations (reflections, rotations) affect nets and learn how optimizing net design minimizes material waste.

Using a hands-on approach, students will analyze different net orientations, construct 3D figures, and explore the impact of net efficiency in manufacturing. They will also solve a practical problem: maximizing the volume of a cereal box using algebraic methods. This real-world connection highlights how math is used in packaging to reduce costs and waste.

Students will apply their knowledge using digital tools like GeoGebra and Tinkercad to manipulate 3D shapes interactively. The lesson includes a detailed step-by-step guide, hands-on activities, and real-world problem-solving tasks.

A 10-question quiz and answer key are included for assessment.
