3D Shapes in the Real World

In this video, we will learn how to recognize 3D shapes in real-world objects and use the names of 3D objects to describe them.

Here’s a ball. What shape is the ball? It’s a sphere. A sphere is a 3D shape. Here’s a party hat. Which 3D shape is it? It’s a cone. You may be used to seeing a cone this way up with some ice cream on top. What’s the name of this 3D shape? It’s a cylinder. This is a cube. All of the surfaces of this 3D shape are made from squares. This box of tissues is called a cuboid. The surfaces of a cuboid are either rectangles or squares. This 3D shape is called a pyramid.

Let’s look at some real-world objects and see if we can name the 3D shapes.

What shape is this?

The surfaces we can see are squares. Can you remember which 3D shape has surfaces made from squares? It’s a cube.

What 3D shape does this look like?

It’s a cylinder.

Which shape is different from the rest?

We’re shown four 3D shapes. We have to pick the one which is different from the rest. The first object is a ball. The name of this 3D shape is a sphere. This beach ball is also a sphere. Spheres have a curved surface. You can roll them. This shape doesn’t have curved surfaces. Its surfaces are flat. They’re rectangles. This is a cuboid. Our fourth shape is another ball and another sphere. So the matchbox is different from the rest. It’s a cuboid. And the other shapes are spheres. This is the shape which is different from the rest.

What have we learned in this video? We’ve learned how to recognize 3D shapes in real-world objects.
