3D SHAPES

What are we learning today?

• We will learn the names of 3D shapes.
• We will learn how they are made up.
• We will learn new ways to describe them.
• We will think about how shapes are all around us.

How do you think we can do this?
3

• We will be able to give examples of 3D shapes
  around us.
• We will be able to describe shapes in detail
  using the correct language.
• We will be able to explain how a 3D shape is made
  up.

4
What is the difference between a 2D shape and 3D
shape?

• Which 3D shapes can you name?

SQUARE BASED PYRAMID

TRIANGULAR PRISM
17
How can we describe these shapes?
18
We can use words like

• FACES
• EDGES
• CORNERS

19
FACES or SIDES

• All 3D shapes have faces.

20
EDGES

• All 3D shapes have edges apart from a sphere.

21
CORNERS OR VERTICES
All 3D shapes have vertices apart from a sphere.
22
We can also say what shape the face is.
The face is the shape of a square.
23
Using these words, how could we describe a cube?

• It has
• 6 faces that are square shaped
• 12 edges
• 8 vertices
