# Geometric Solids and Their Properties: Making a Shape Jacket

This is Lesson 5 of a 5 lesson series.  This activity uses grid paper for students to create nets (jackets) of 3-D forms.  Students must use visualization and spacial reasoning to create a 2-D representation of a 3-D solid. Students must use visualization and spacial reasoning to create nets in 2-D of 3-D solids.

Alignment of this item to academic standards is based on recommendations from content creators, resource curators, and visitors to this website. It is the responsibility of each educator to verify that the materials are appropriate for your content area, aligned to current academic standards, and will be beneficial to your specific students.

Learning objectives:

Students will:

• Analyze characteristics and properties of three dimensional geometric shapes and develop mathematical arguments about geometric relationships.
• Use visualization, spatial reasoning, and geometric modeling to solve problems.
• Identify which geometric solids can be made from given nets.
• Create nets for common geometric solids.

### Lesson Variations

Blooms taxonomy level:
Understanding
Extension suggestions:
• Students can create nets for some of the more complex geometric solids, such as the octahedron, dodecahedron, icosahedron, and an irregular polyhedron.
