Students I want you to tell me what you understand by Nets of solids. ( Discussion will be ensued about where they have ever seen these nets and how they can be created.) Let us take a look at the definition below.
FOLLOW UP PRACTICE EXERCISES
Grade Level: 6
Strand: Geometry
Topic: Nets of Solids
Focus Question: What are the properties of solid figures?
Duration: 1 Hour
Objectives:
By the end of the lesson, students should be able to:
-
Recognize faces, edges, and vertices of solids and classify solids according to the number and shape of their faces.
-
Describe, design, or create three-dimensional shapes.
-
Describe the physical world in terms of geometric concepts and talk about mathematical findings.
5E Lesson Plan Model
Engage (10 minutes)
Activity: Solid Shapes Mystery Box
-
Place several 3D solids (cube, prism, pyramid, cylinder, etc.) in a box or bag.
-
Let students reach in, feel one without looking, and describe the shape based on touch (faces, edges, vertices).
-
Ask:
“What did you feel?”
“How many faces do you think it has?”
“Can you guess the shape?”
Purpose: Activates prior knowledge of 3D shapes and introduces geometric properties (faces, edges, vertices).
Explore (15 minutes)
Activity: Build and Examine Nets
-
Distribute cut-out nets (paper or cardstock) of various solids (cube, triangular prism, square pyramid).
-
In pairs, students fold and construct the 3D shapes.
-
Guide them to count and record:
-
Number of faces, edges, and vertices
-
Shape of each face
-
STEM Integration:
-
Discuss real-life applications: packaging design, architecture, 3D modeling.
-
Students briefly research (or are shown pictures of) how engineers use nets to design 3D objects.
Explain (10 minutes)
Activity: Anchor Chart & Discussion
-
Create a class chart listing solids with their number of faces, edges, vertices, and face shapes.
-
Use visual models (projected diagrams or digital tools) to match solids with their nets.
-
Highlight how nets relate to surface area and structure in real-world designs.
Vocabulary: Face, edge, vertex, net, solid figure, prism, pyramid, cylinder, cone, cube.
Elaborate (15 minutes)
Activity: Design Your Own Net (Creative STEM Task)
-
Students select a real-world object (e.g., cereal box, tent, can) and sketch or build a net for it.
-
Use graph paper or a net template app/tool to help them design accurately.
-
Share and explain their creations in small groups.
Complete activities on teacher's blogsites on their chromebooks
Differentiated Learning:
-
Tier 1 (Support): Pre-cut nets to fold and label
-
Tier 2 (On-Level): Complete a partially drawn net and describe the 3D object it forms
-
Tier 3 (Advanced): Create an original net for a given shape and write about its real-world application
Evaluate (10 minutes)
Three-Tier Evaluation Activity
| Tier | Task | Objective Measured |
|---|---|---|
| Tier 1: Basic | Match a net to its 3D shape and list its number of faces, edges, and vertices. | Objective 1 |
| Tier 2: Intermediate | Given a 3D shape, sketch its net and label its parts (faces, edges, vertices). | Objectives 1 & 2 |
| Tier 3: Advanced | Create and explain a real-life scenario where understanding nets is necessary (e.g., designing a gift box). Present findings to the class or in a written paragraph. | Objectives 2 & 3 |
Assessment Tools:
-
Observation checklist
-
Student-created models and nets
-
Group presentation or short written response
Closure (Optional Exit Ticket Prompt)
“What is one solid you used today? How many faces does it have, and what shapes are they?”
