How Solid Are Your Geometry Skills?
Digital Tool/Resource:
Geometric Solids Tool
Web Address – URL:
Overview:

The Illuminations tool called Geometric Solids is an excellent way to enhance a lesson and provide students with a deeper understanding of the properties of geometric properties. This tool will help students learn the relationships between vertices, faces, and edges. This tool can help students master finding the surface area of three-dimensional figures. This tool also demonstrates the relationship between the solid shapes and their nets.

Alabama Alternate Achievement Standards
AAS Standard:
M.AAS.6.24- Identify a three-dimensional shape (cube, cone, cylinder) and match it to its nets.


Learning Objectives:

Students will:

  • manipulate and identify the number of faces, vertices, and edges of three-dimensional shapes.
  • compare and contrast three-dimensional shapes and their nets.
  • create their own net.
  Strategies, Preparations and Variations  
Phase:
After/Explain/Elaborate
Activity:

The Geometric Solids tool can be used to extend a lesson the properties of three-dimensional shapes after the core lesson has been taught.

  1. Pull up the Geometric Solids tool for the students to see. 
  2. Model what the different tools within the application can do.
  3. Have the students go to a computer and navigate to the digital tool.
  4. Let the students explore the tool and manipulate the shapes for about 3 minutes to explore their curiosity. 
  5. Ask the students, "How could this tool give you a better understanding of the shapes? Where have you seen these solids in real-life?"
  6. As a class activity, have everyone pull up the same shape. Write the student's predictions of the number of edges, vertices, and faces for the shape. Let the students use the tool to check and see if they are correct.
  7. Have the students create a graphic organizer that compares and contrasts the properties of each solid.
  8. Have the students either individually or with a partner create a net and print it out. The students will fold the net into the geometric shape and present to the class.
Assessment Strategies:

1. Ask each student individually to orally identify the number of faces, vertices, and edges of the three-dimensional shapes.

2. Check the students' graphic organizers that analyzed the properties of solids for accuracy.

3. Have the students share the net they created with the class. In their presentation, they must identify all faces, edges, and vertices of their shape.


Advanced Preparation:

Students should have knowledge of how to perform basic computer operations such as working mouse and printer. Students should already be able to identify what the faces, vertices, and edges are on a three-dimensional shape.

Variation Tips (optional):

This tool could also be used as an opening to a lesson to get the students engaged and curious about the properties of geometric solids.
