00:00Hi kids! Today we will learn what are 2D and 3D shapes. Let's start!

00:11Kids, can you put anything in this shape? Think!

00:17No, you cannot put anything in this shape.

00:22So, such shapes where you cannot put anything in them are 2D shapes.

00:30They are so called because they have only two dimensions, that is, breadth and length.

00:40So, what have we learned?

00:45We have learned that 2D shapes are those shapes where we cannot put anything in them.

00:53And they have only two dimensions, length and breadth.

01:00Good!

01:04Kids, can you put anything in this shape?

01:08Yes, you can put something in this shape.

01:13So, such shapes where you can put something in them are called 3D shapes.

01:22And they are so called because they have three dimensions.

01:29One more dimension than 2D shape.

01:34Have a look!

01:37It has depth also.

01:41So, 3D shapes are those in which we can put something in them.

01:49And they are so called because they have three dimensions.

01:56Length, breadth and depth or height.

02:03Here we have a picture.

02:05Is it a 2D shape or a 3D shape?

02:10This shape has three dimensions.

02:13It has length, breadth and height too.

02:17So, it's a 3D shape.

02:20Here we have another shape.

02:22Is it a 2D shape or a 3D shape?

02:27This shape has only two dimensions, length and breadth.

02:32No height.

02:34So, it's a 2D shape.

02:37Here we have another object.

02:40Now we have to tell.

02:42Is it a 2D object or a 3D object?

02:47Can we put something in this object?

02:51Yes!

02:52And how many dimensions does it have?

02:55It has length, it has breadth and it has height too.

03:00So, it's a 3D object.

03:03Now we have one more object.

03:06We have to tell that.

03:08Is it a 2D object or a 3D object?

03:13Can we put something in this object?

03:16Yes!

03:17We can put something in this object.

03:21How many dimensions does it have?

03:24It has length, breadth and height.

03:28So, it's a 3D object.

03:32Now one more object.

03:35We have to tell that.

03:37Is it a 2D object or a 3D object?

03:43It's a paper.

03:45This object has only two dimensions, length and breadth.

03:52And also, we cannot put something in this object.

03:56So, it's a 2D object.

03:59So kids, today we learned what are 2D and 3D shapes.

04:05Now you may go ahead and take a quiz to learn more.

04:09Bye-bye!
