Shapes Around us Video Lecture | Mathematics for Class 2 (Joyful-Mathematics)

0:0:0: hello
0:0:1: students today we are going to study
0:0:3: about shapes around
0:0:5: us this video is about
0:0:8: shapes we have learned about some shapes
0:0:11: in class
0:0:12: one like circle square rectangle
0:0:17: Etc all these are called 2D shapes but
0:0:21: there are many other shapes around us as
0:0:23: well like look at this
0:0:26: picture what do you see you see a ball a
0:0:31: bottle a dice a pencil box and a
0:0:34: birthday cap you notice how these shapes
0:0:38: are very different from the 2D shapes 2D
0:0:42: shapes are flat but these are
0:0:44: fat these are called 3D
0:0:47: shapes we will see how these shapes are
0:0:50: all around
0:0:52: us now I will show you some objects and
0:0:55: you have to tell me what they look like
0:0:58: look at this what do you you see yes
0:1:2: it's an orange and what does it look
0:1:5: like it looks like a ball what does this
0:1:9: crayon looks like looks like the bottle
0:1:13: right yes what does this eraser looks
0:1:17: like it looks like the pencil
0:1:20: box now what does this ice cube looks
0:1:24: like it looks like a
0:1:26: dice now tell me what does this ice
0:1:29: cream looks like
0:1:31: yes it looks like the cap here now these
0:1:34: shapes also have some names let us look
0:1:38: at them quickly all the shapes that
0:1:41: looks like this ball are called
0:1:43: spheres for example an apple here all
0:1:47: the shapes that looks like this bottle
0:1:49: and crayon are called
0:1:51: cylinders what do we call the shapes
0:1:54: that looks like this Ludo dice we call
0:1:57: it cubes and this shape shape of a
0:2:0: pencil box is called
0:2:2: cuboid and lastly this shape of a cap is
0:2:5: called a cone have you eaten ice cream
0:2:9: what shape does it have it's a corn
0:2:12: right yes notice how all these look so
0:2:17: different from each other what makes
0:2:20: them
0:2:21: different let's find out look at this
0:2:25: Cube it has some flat sides it also has
0:2:28: pointy corners
0:2:30: and see it has lines
0:2:32: too these flat sides are called
0:2:35: faces we call these pointy Corners
0:2:38: corners or
0:2:40: vertices and the line joining these
0:2:42: Corners are called
0:2:44: edges these three makes the shapes
0:2:46: different from each other so how many
0:2:50: faces does a cube has let's count them
0:2:54: together 1 2 3
0:3:0: four
0:3:1: five and
0:3:3: six as you can see the cube has six
0:3:7: faces now let's count the
0:3:10: corners Four Corners here and four
0:3:13: corners down here so the cube has eight
0:3:17: Corners now let's count the
0:3:21: edges it has four edges here four edges
0:3:24: here two edges here and two edges here
0:3:28: so it has 12 edges
0:3:30: es now see this
0:3:33: cuboid how is it different from a cube
0:3:36: it also has six faces eight corners and
0:3:39: 12
0:3:40: edges but in Cube all the faces are
0:3:44: equal see but in cuboid these four faces
0:3:49: are long and these two faces are
0:3:51: small now how many faces does the sphere
0:3:55: have it has only one face and and it is
0:4:0: all round so it has no pointy Corners
0:4:3: anywhere and no
0:4:4: edges how many faces does this cylinder
0:4:8: have it has three faces see one at the
0:4:11: top one at the bottom and one here in
0:4:14: the middle it also does not have any
0:4:18: corners but it has
0:4:20: edges can you point out
0:4:23: where yes one edge here and one edge
0:4:27: here how many faces does the one have it
0:4:31: has one face here at the bottom and one
0:4:34: face here it has a very pointy corner so
0:4:37: it has one corner as well it also has an
0:4:41: edge here at the
0:4:43: bottom see how different each shape is
0:4:48: great now that you have seen so many
0:4:51: shapes look around you and see how
0:4:53: shapes are all around
0:4:55: us we hope that you have understood the
0:4:58: concept of shape around us now here's a
0:5:2: secret on how you can study effectively
0:5:5: with the uref app you can learn with
0:5:8: chapter notes watch video lectures and
0:5:11: solve ncer based McQ tests of this
0:5:15: chapter on
0:5:16: eduv and that's not all you also get
0:5:19: amazing courses for Class 2 and much
0:5:22: more for your class 2
0:5:24: preparation thank you
