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?

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.

What is the difference between a 2D shape and 3D shape? Which 3D shapes can you name?

CUBE Can you think of any objects which are the shape of a cube?

CUBOID Can you think of any objects which are the shape of a cuboid?

SPHERE Can you think of any objects which are shape of a sphere?

CONE Can you think of any objects which are the shape of a cone?

CYLINDER Can you think of any objects which are the shape of a cylinder?

SQUARE BASED PYRAMID

TRIANGULAR PRISM

How can we describe these shapes?

We can use words like… FACES EDGES CORNERS

FACES or SIDES All 3D shapes have faces.

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

CORNERS OR VERTICES All 3D shapes have vertices apart from a sphere.

We can also say what shape the face is. The face is the shape of a square.

Using these words, how could we describe a cube? It has… 6 faces that are square shaped 12 edges 8 vertices
