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.
