🌟 Faces, Edges & Vertices 🌟

Hi my amazing Grade 6 3D explorers! 👋

Today we’re learning the three important parts of 3D shapes: Faces, Edges, and Vertices! These words help us describe and understand cubes, pyramids, prisms and many other solids. Let’s become experts at counting them! 📦✨

⬛ 📐 🔢

1. What Are Faces, Edges & Vertices?

📄

Faces

Flat surfaces
Each side of the shape

📏

Edges

Lines where two faces meet

🔵

Vertices

Corners (points)
Where edges meet

2. Let’s Look at a Cube

F

B

R

L

T

Bo

A Cube has:
6 Faces • 12 Edges • 8 Vertices

3. Common 3D Shapes

Shape	Faces	Edges	Vertices
Cube	6	12	8
Rectangular Prism	6	12	8
Triangular Prism	5	9	6
Square Pyramid	5	8	5
Cone	2	1	1

4. Let’s Practice Together! 🎉

Question 1

How many faces does a cube have?

6 faces ⭐

Question 2

A triangular prism has how many edges?

9 edges ⭐

Question 3

True or False: All 3D shapes with 6 faces have 12 edges and 8 vertices.

True for cubes and rectangular prisms ⭐

5. In Real Life 🇨🇦

• Dice, cereal boxes, and buildings (cubes & prisms)
• Pyramids in ancient structures
• Hockey pucks and pucks are cylinders
• Tents (triangular prisms)
• Designing toys and packaging

You are now a 3D Shape Expert! 🌟

Great job! You can now count faces, edges, and vertices like a pro.

Look around your room — how many faces, edges, and vertices can you count on different objects?

Love and proud high-fives,
Mrs. Brenda ❤️
