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!
