Nets of 3D Figures | 4-Lesson Unit

This comprehensive lesson plan collection explores the relationship between 2D nets and 3D geometric figures. Through hands-on activities, interactive animations, and real-world applications, students will learn how nets fold into 3D shapes and how these concepts apply in engineering, architecture, and design.

Each lesson focuses on different aspects of nets and 3D figures:

• Lesson 1: Introduction to basic 3D shapes, including cubes, prisms, and pyramids.
• Lesson 2: Exploring more complex polyhedra, including the tetrahedron, octahedron, and dodecahedron.
• Lesson 3: Applying nets to real-world structures and calculating surface area.
• Lesson 4: Advanced applications, including Euler’s Formula, geometric transformations, and optimization in packaging design.

Students will develop a deep understanding of spatial reasoning, geometric properties, and problem-solving through interactive activities and digital tools like GeoGebra and Tinkercad. Each lesson includes a quiz and answer key to assess student learning.
