🌟 Prisms & Pyramids Detective 🌟

Hi my super Grade 6 detectives! 👋

Today we’re learning how to classify two big families of 3D shapes: Prisms and Pyramids! We will discover what makes them different and how to name them. Get your detective hats on — let’s investigate! 🔍📦

🔺 📦

1. What is a Prism?

⬛

Prism

• Has two identical parallel bases (same shape)
• Sides are rectangles (in right prisms)
• Named by the shape of its base

Examples: Triangular Prism, Rectangular Prism, Pentagonal Prism

2. What is a Pyramid?

🏔️

Pyramid

• Has one base (any polygon)
• All other faces are triangles that meet at one point (apex)
• Named by the shape of its base

Examples: Square Pyramid, Triangular Pyramid (Tetrahedron)

3. Prisms vs Pyramids

Feature	Prism	Pyramid
Bases	2 identical parallel bases	1 base
Side faces	Rectangles	Triangles
Vertices	Base vertices × 2	Base vertices + 1 apex
Example	Rectangular Prism (like a box)	Square Pyramid

4. Let’s Practice Together! 🎉

Question 1

A 3D shape has two triangular bases and three rectangular sides. What is it?

Triangular Prism ⭐

Question 2

A shape has one square base and four triangular faces. What is it?

Square Pyramid ⭐

Question 3

How many faces does a pentagonal prism have?

7 faces (2 pentagons + 5 rectangles) ⭐

5. Real Life in Canada 🇨🇦

• Cereal boxes and tissue boxes = Rectangular prisms
• Toblerone chocolate = Triangular prism
• Egyptian pyramids (and glass pyramids in museums)
• Roof shapes of many houses = Pyramids
• Tents and camping structures

You are now a Prism & Pyramid Expert! 🌟

Wonderful work today! You can now look at any 3D shape and tell if it’s a prism or a pyramid and name it correctly.

Keep your eyes open — these shapes are all around us!

Love and proud high-fives,
Mrs. Brenda ❤️
