00:00	wow , we are going to learn so many cool
00:03	things on this home school pop video . All right
00:06	. What's the first thing we should learn ? How
00:09	about addition ? I love Edition . I love it
00:16	very much . I love Edition . I add up
00:19	all my stuff . I know the voice of an
00:22	angel . All right , So , really ? Why
00:27	do I love audition ? Why do I love Edition
00:31	? And why should you love Edition ? Well ,
00:35	I love Edition . Because Edition is so simple and
00:40	so much fun . We're gonna show you were gonna
00:43	prove to you that addition is so simple and so
00:46	much fun . You're gonna have a great time doing
00:49	it . Okay , So , you might be wondering
00:52	what is addition ? What do we do when we
00:54	do addition ? Well , addition is putting numbers together
00:58	. It's like a great game of putting numbers together
01:03	. Okay , addition is putting numbers together . Now
01:09	we're going to show you exactly how this works by
01:12	talking about this sport . Do you know what sport
01:18	this is ? Okay ? Mhm . Yeah , this
01:23	is golf . Mhm . This lady hit the golf
01:29	ball and she's hoping that the golf ball goes into
01:33	the hole . We're pulling for you sally . Don't
01:37	know if you actually got the ball in the hole
01:39	but we're pulling for you Sally . You can do
01:41	it sally , you can do it . You see
01:43	she's so excited . She doesn't know . She doesn't
01:46	know . But we don't know either . So anyway
01:50	, all we can do is guess we don't really
01:52	know sally all that well . But let's pretend that
01:57	Sally loves golf and let's pretend that Sally likes to
02:02	collect golf balls . So sally is playing with one
02:09	golf ball . Let's say that's the only golf ball
02:13	she has with her right now she's got one golf
02:16	ball but she finds another golf ball by a tree
02:24	. So she had one golf ball and then she
02:27	found another one . We need to put these numbers
02:32	together don't we to find out how many golf balls
02:35	she has now putting numbers together . That's that's addition
02:40	, that's addition . So now we put these two
02:45	numbers together , she had one golf ball , she
02:49	found another one . So let's add both of those
02:53	balls , how many do we have ? Mhm Yeah
02:59	to sally now has two golf balls . Good job
03:05	sally , oh audition I knew I loved you audition
03:11	. All you are is just putting numbers together .
03:15	So simple , so fun a game anyone can play
03:21	well you know sally you know sally she went back
03:26	to that golf course the very next day because remember
03:30	she loves golf right and of course sally brought her
03:36	to golf balls because remember she had one golf ball
03:39	and she found another one so now she has to
03:42	but you know what , she had a great day
03:44	at the course and she actually found two more balls
03:49	. I know and that crazy sadly is really great
03:53	at finding golf balls . She found two more balls
03:59	. Now we have to find out how many golf
04:02	balls she has . Wait a second . We're putting
04:06	that we're putting numbers together . It's addition it's time
04:09	we're gonna get to through addition again . Remember addition
04:12	is putting numbers together . She had two balls and
04:16	now she's found two more balls and we get to
04:19	find out how many she has now that's edition putting
04:23	numbers together . So she had two balls and she's
04:29	found two new ones . So we need to find
04:31	out what two plus two is . What a great
04:36	addition problem . What's two plus two ? If you
04:40	don't know you can actually just count the golf balls
04:44	. What's two plus two ? Yeah 42 plus two
04:51	equals four . Remember addition is putting numbers together .
04:59	Two plus two equals four . That's addition putting numbers
05:06	together . Oh bless her heart . Sally's at it
05:13	again . She's back at the golf course to collect
05:18	more golf balls . So sally brings all of her
05:23	golf balls now she has four of them . She
05:27	brought all four to the golf course . Well she
05:32	looked high and low and wouldn't you know it ?
05:35	She found three golf balls during her time at the
05:39	golf course . I know she's so good at collecting
05:42	golf balls . Now we need to figure out how
05:47	many golf balls she has and yes we're putting numbers
05:50	together so it's going to be an addition problem .
05:54	She had four golf balls and now she has three
05:59	more golf balls . So what is four plus three
06:06	? Remember with addition we're just putting numbers together so
06:12	if you need help you can actually count the number
06:15	of golf balls on the screen . What's four plus
06:19	three ? Yeah , four plus three equals seven .
06:29	She has seven golf balls now . Great job adding
06:36	. Well , now , you know , the basics
06:39	of audition and now , you know why I love
06:42	auditions so much in the comments below , Tell us
06:46	how much you love edition , because it's fun ,
06:49	right ? It's simple . It's fun . Where sally
06:52	, where sally , ah , there she is ,
06:55	she is , There's our little star . Thanks for
06:58	helping us count how many golf balls chicha . And
07:01	remember addition is just putting numbers together . We are
07:07	so happy to have you with us . I mean
07:09	, you are so awesome , You really are .
07:13	Oh , you like my poster , Mr Whiskers poster
07:16	, You know , it's pretty cool , pretty cool
07:19	. You know , it's a pretty cool poster .
07:22	Pretty cool cat too . I wonder what he would
07:24	like to learn about next . If he would learn
07:27	from one of our videos , what would he like
07:29	to learn next ? How about , let's learn about
07:37	equal parts . We're going to learn how to recognize
07:41	if something shows equal parts or if something shows unequal
07:46	parts . Hold on . My , my boss is
07:53	giving me his pizza order again . I'm telling you
07:56	he loves pizza way too much . I mean I
07:59	like pizza . It's fine , but he's always giving
08:03	me his pizza order . I'm always picking it up
08:05	for him and this is just , this is uh
08:09	, you know , I just here , I just
08:11	got to keep writing down , You know , he's
08:12	got all these instructions . He likes his pizza a
08:15	certain way . Oh wow . Oh , he's ,
08:20	he wants , he wants me to have some of
08:22	the pizza with him . Oh , man and and
08:25	Tad and and Gilbert . Oh , all four of
08:29	us having the same pizza . All the sharing of
08:33	pizza . So what would that look like ? What
08:38	would it look like if we had this pizza put
08:41	in four equal parts ? How would we know that
08:46	these parts of the pizza were equal mm A pizza
08:53	with four equal parts . Might look like this .
08:56	Pretty cool . Huh ? We know the parts are
09:01	equal because each of the parts are the same size
09:08	. Mhm . We're going to play a game called
09:12	Are these equal parts ? Okay . It's not really
09:17	a game but we can make it into a game
09:19	, right , Okay . It's not like checkers ,
09:22	It's not like chess . You know , it's not
09:24	like basketball , like soccer . Okay . It's not
09:28	like a game game game . Okay . But it's
09:31	still going to be fun and we're gonna be able
09:34	to see work with me or Okay , we're gonna
09:37	be able to see if these pictures show equal parts
09:43	or if these pictures show unequal parts . So here
09:50	is our first picture . Now we're gonna be looking
09:53	to see if this picture shows equal parts and this
09:58	picture shows how many parts . Two good job now
10:04	are these equal parts ? Yes this picture shows two
10:14	equal parts and we know they're equal because they're the
10:17	same size . Now look at this one . This
10:23	picture shows how many parts Yeah three parts . Now
10:30	are these equal parts ? No they're not equal parts
10:36	. They're not equal parts because they're not all the
10:39	same size . This picture does not show equal parts
10:45	. Great job . Now let's give this picture .
10:50	Try how many parts to this picture show three good
10:57	job . And are these parts equal parts . No
11:05	they're not equal parts . Can you imagine if you
11:08	got that bottom part ? If this if this square
11:11	was like a cake and you've got that bottom part
11:14	. That wouldn't be fair . Why these are not
11:16	equal parts . Let's give this triangle picture a try
11:23	. How many parts does this picture show ? Great
11:28	Job . three . And are these equal parts ?
11:35	Yeah . Yes they're equal parts because they are all
11:39	the same size . Equal parts means each part is
11:43	the same size . Great job . What about this
11:50	picture ? How many parts does this picture have ?
11:54	Be careful when you count . It's a little bit
11:57	tricky . This picture has four parts . Now .
12:04	Are these equal parts ? No they're not equal parts
12:10	. How do we know because they're not the same
12:13	size ? I don't know about you but I feel
12:20	pretty good about this . Equal parts stuff . It
12:23	just means that the parts are the same size when
12:26	they're the same size . That means they're equal oh
12:31	this little baby is putting together a little craft you
12:35	know it's so great . I just love that .
12:37	This has so good . Wait a second . Papers
12:41	from that book , isn't it ? Okay , this
12:44	is , see this is , this is not an
12:46	approved arts and crafts activity right now . Okay ,
12:51	we're gonna have to take care of this . But
12:53	first let's learn about subtraction . Oh , do you
13:04	know where I am ? Yeah . You know ,
13:07	I'm waiting patiently in this waiting room . Oh man
13:12	, it has been a while . Have you ever
13:15	been in a waiting room before ? Cool . Yeah
13:23	, they can be fun but you do have to
13:24	be patient and it's a good time to think ,
13:27	you know , you can think about all kinds of
13:29	things like , okay , I have eight cowboy hats
13:35	. I know it's crazy . It's weird . Eight
13:37	cowboy hats and they're all the exact same . The
13:41	exact same hat . I've got eight of them .
13:44	Eight brown cowboy hats . I mean what's the guy
13:49	going to do with eight brown cowboy hats that look
13:53	the exact same ? What could I possibly do with
13:58	eight brown cowboy hats that are all the same .
14:02	I mean I should probably give some of them away
14:05	. You know , I could give away one of
14:08	my hats to bob . I'm cooking , might want
14:11	one . Yeah , she might like a brown cowboy
14:13	hat , you know , I can give one a
14:16	nancy , you know just in case she ever got
14:18	invited to western party and chomsky , he'd take a
14:22	hat . So as I'm sitting here thinking about my
14:27	eight hats , I need to figure out how many
14:29	hats I'll have left if I give some of them
14:32	away to figure that out . We need to use
14:37	subtraction . You see subtraction is when you take numbers
14:42	away . Yeah , very simple subtraction is when you
14:45	take numbers away . So I begin with eight hats
14:51	and I decided to give one away . We're gonna
14:55	need to subtract one from eight . The way we
14:59	would write this is 8 -1 . Now remember when
15:06	we subtract we're just taking numbers away so 8 -1
15:11	we're gonna just take one away . There we go
15:15	. How many hats do I have left ? What
15:18	is 8 -1 ? If it helps you can just
15:22	count how many hats I have left . What is
15:26	8 -1 ? Mm . Yeah seven eight minus one
15:34	is seven . Now I have seven hats . Remember
15:41	subtraction is when you take numbers away and as you
15:46	might have noticed we use the minus sign when we
15:49	write a subtraction problem you can see it right there
15:53	in the middle . It's just like a dash that's
15:56	the minus sign . So now I have seven hats
16:01	but two of my friends stopped by and I decided
16:03	you know what I know I just have seven hats
16:06	now but I want to give two of them away
16:09	. Now I'm gonna be subtracting two hats from my
16:13	collection . We would write this by saying 7 -2
16:21	. Now let's take away two hats . We'll find
16:23	out how many we have left . What a wonderful
16:26	subtraction problem . What is 7 -2 . If you
16:32	need help you can just count how many hats are
16:34	left . What is 7 -2 ? Seven minus two
16:40	equals five . Yeah . Five hats . And you
16:44	can even count them 12345 There are five hats left
16:49	. Seven minus two equals five . Do you see
16:55	how fun and simple subtraction is ? Subtraction is when
16:59	you take numbers away . So now I have five
17:04	hats in my collection . Only five hats left .
17:08	But then I meet up with my cousins who we
17:11	dewey and Stewie who want to have hats too and
17:15	I'd love to give them hats so I'm gonna give
17:18	three more hats away . So I have five hats
17:22	and we're gonna subtract three hats , we would write
17:25	that five minus three . Oh I love subtraction so
17:33	much . Alright Bada Bing . There we go .
17:38	The three hats are gone , so 5 -3 .
17:43	How many hats are left ? It's pretty simple ,
17:47	isn't it ? Mhm , mm hmm . Yeah 5
17:54	-3 equals two . Good job . Subtraction is just
17:59	taking numbers away and 5 -3 leaves you with two
18:04	. Now I have just two hats . We love
18:08	subtraction . I mean subtraction is when you take numbers
18:13	away and why am I in the middle of the
18:16	road with the shopping card ? So I had my
18:23	two hats and that's fun because then the hat has
18:27	a friend and they're like buddies and they're like a
18:30	pair of friends and then chomsky came by and I
18:38	said oh I'm going to have to do subtraction again
18:43	, I'm going to have to subtract again . Old
18:45	chomsky , you know the charms the game by ,
18:50	I said I'm going to have to subtract again Mhm
18:55	I'm going to have to subtract one more time ,
19:01	so I have two hats minus one , 2 -1
19:09	. So we subtract that one , we take that
19:13	one away and how many hats are left ? What
19:17	is 2 -1 , yep , 2 -1 equals one
19:28	. There's only one hat left , which is fine
19:31	. I mean you know , I can only wear
19:33	one hat at a time and it was the same
19:36	exact hat I think about it . Subtraction has been
19:40	good to me , it's good . Subtraction is taking
19:43	numbers away Sometimes . I do wonder what would have
19:50	happened if I didn't give that Hattaway . If if
19:55	hat he still had his friend they could have gone
19:58	to the beach together . They could have gone to
20:01	birthday parties together . But actually they had a better
20:08	purpose to make a friend happy . So in this
20:13	waiting room , all I got to say is thanks
20:17	subtraction . You are pretty awesome . Oh this is
20:29	such a heavy cart . Oh my goodness . It's
20:33	hard work . You know A lot of times learning
20:35	can be hard work too . But we hope that
20:38	these videos are really helpful . Make learning fun .
20:41	So that learning is hard like pushing this cart .
20:45	Oh my goodness ! All right . What's the next
20:48	thing we should learn about ? Let's learn about even
20:53	and odd numbers . A number belongs to one of
20:57	two groups . Either it's an even number or it's
21:00	an odd number . So what's going on ? Why
21:03	is this even a thing we're going to talk about
21:06	it even in odd is actually pretty easy , but
21:12	it's just a matter of knowing what to look for
21:15	. So we're going to be like detectives together .
21:17	Okay , You're gonna have to have an eagle ,
21:20	uh , to help us out on her quest .
21:23	We're gonna use dinosaurs , dinosaurs are awesome . And
21:27	here's a red dinosaur . That's I don't know why
21:30	it's windy . There's wind going on . And I
21:33	don't know what's what's let's change the scenery . Let's
21:36	let's make it more modern day . There you go
21:39	. Look at that . Just walking through the neighborhood
21:41	strolling . He's ready to help us discover the secret
21:48	, right to knowing even an odd . So what
21:52	is this key that we're looking for ? What are
21:54	we looking for that will tell us if a number
21:56	is even or if the number is odd and even
22:02	number can be grouped by to an odd number cannot
22:07	be evenly grouped by two . So it's all about
22:10	the number two . And that might sound confusing .
22:12	Let me show you and you'll see here is the
22:16	easiest number to do . We're looking for the number
22:20	two . Okay . Can it be put in a
22:23	group of two ? Well yes because it's the number
22:25	two . We've got to dinosaurs . That makes to
22:28	even now this is odd . This dinosaurs All alone
22:34	. He's not in a group of two . This
22:36	makes the number one an odd number because he's all
22:40	alone . That's odd . It's an odd number .
22:45	Let's look back at the number to see what's neat
22:48	about . This is it's an even group of two
22:51	. That means our dinosaur has a friend , he
22:53	can talk to his friend , he can hang out
22:55	. It's not it's not weird . It's not odd
22:58	. It's an even number here . We have three
23:01	dinosaurs . Now can we put the number three in
23:05	even groups of two ? Well no because that third
23:08	dinosaurs all alone . The top two dinosaurs have somebody
23:11	three is odd . There's one that's missing a partner
23:15	here we have four dinosaurs . Now we're looking for
23:19	groups of the number two . Now we have two
23:22	groups of . To hear . That means it's an
23:24	even number . Each dinosaur has a friend , wow
23:31	five dinosaurs but look One on the bottom doesn't have
23:36	a pal , doesn't have a friend . That's odd
23:40	. It's not evenly grouped into 25 is an odd
23:44	number . Hey buddy . Okay . Don't don't run
23:47	. Okay , we'll get back to the even numbers
23:49	. I know you don't like the odds . You
23:50	don't like being the odd dinosaur out . It's okay
23:53	. I promise this next number is going to be
23:56	even because it goes for even odd , even odd
23:59	. Just hang on man dinosaurs . You know ,
24:04	so temperamental . You know I mean what's that all
24:08	about ? I mean a dog , dog wouldn't have
24:10	done that . You know , dogs are better I
24:13	think now than dinosaurs . You know , I'm just
24:18	kidding , dinosaurs are so cool . Moving on here
24:27	we have six dinosaurs now . Each dinosaur has a
24:32	friend . That means six is even . You can
24:36	split it up in groups of two . Oh here
24:42	we have seven dinosaurs . But there's one dinosaur that's
24:46	all alone . Six of them have friends . But
24:49	one is all alone . Doesn't have a pair .
24:51	Seven is odd for the number eight . Does everyone
24:59	have a friend ? Yes , there's no one without
25:02	a friend . Number eight is an even number .
25:06	It splits up into two very nicely . Eight is
25:09	even let's go even higher than number nine . Now
25:14	you can see really quick , it's easy to spot
25:17	is nine even or odd . Yes , it's odd
25:22	. There's one who doesn't have a friend . Nine
25:24	Izod . Oh my goodness . 10 . 10 is
25:29	it even or is odd ? You tell me you
25:33	know how to do it now . You know the
25:34	trick ? Yes , 10 is even everybody has a
25:39	friend . Now we're about to teach you to sneaky
25:45	tricks that you can use with even and odd numbers
25:49	. Okay , so seriously ? Because it's well it's
25:53	it's not it's not really sneaky . But anyway ,
25:57	so this first trick is that all of the numbers
26:00	alternate from odd to even and back . And we're
26:05	going to show you what that means and what that
26:08	looks like . Here we have the 1st 10 numbers
26:14	, numbers one through 10 . And the trick was
26:17	all of the numbers alternate from odd to even and
26:21	back . Do you remember if number one is odd
26:24	or even ? Yeah . Yes . Number one is
26:30	odd because remember number one all by himself doesn't have
26:33	a friend , doesn't have a partner . It's not
26:35	an even number . Number one is odd . Now
26:39	we remember number two right . Number two is even
26:44	. Yes because it can be grouped into because it
26:46	is too . Now if they alternate that means which
26:50	one is number three it's odd . This is where
26:58	it gets fun . If three is odd then that
27:01	means four is yeah even good job . And if
27:08	four is even , that means five must be odd
27:14	. Yeah and if five is odd , that means
27:18	six must be you guessed it even and if six
27:24	is even , that means seven must be odd .
27:30	Yes seven is odd . If seven is odd that
27:34	means eight is come on . What's the pattern ?
27:37	Eight is even and if aid is even , that
27:41	means night must be odd and nine is odd .
27:46	Come on . Is this not just the most fun
27:48	drink ever ? If nine is odd , that means
27:53	10 is even . They all alternate . So the
27:58	first trick is that they alternate , the numbers alternate
28:02	, odd , even odd , even odd , even
28:06	odd , even odd . Even now . We're going
28:09	to look at the second trick . The second trick
28:12	is that with numbers bigger than 10 If it's odd
28:16	or even you can see on the end With numbers
28:21	bigger than 10 . If it's odd or even you
28:23	can see on the end to demonstrate , let's play
28:30	a game . We here at home school pop call
28:33	Odd or even . We're gonna look at a number
28:37	that's bigger than 10 . We're gonna look on the
28:39	end to see if it's even or if it's odd
28:43	. Our 1st 1 is the number 21 . Is
28:46	it odd ? Or is it even ? It's odd
28:52	. How why what we look on the end ?
28:55	The end is a one . A one is odd
28:58	. It's all by itself . A one is odd
29:02	. So 21 is odd because one is the ending
29:06	. It did . You know ? That means 71
29:12	is odd and 101 is odd and 131 is odd
29:18	and the number 1000 and one is odd . Why
29:21	they all end in ? What ? Let's try this
29:25	one . The number 32 . Is it odd ?
29:28	Or is it even 32 is even ? Well how
29:36	do we know because of the ending ? Look at
29:38	the ending , it's the number 22 is an even
29:41	number because it's a group of two . It can
29:44	be put in groups of two because it is to
29:47	the same rule applies . This is the second trick
29:50	with numbers bigger than 10 if it's odd or even
29:53	you can see on the end every single number that
29:58	you can think of ends in two is an even
30:02	number . Let's try one . That's a little more
30:09	tricky . Let's try the number . 100 is 100
30:13	odd or is it even 100 is even ? It's
30:26	even and we know that because of the ending ,
30:29	it ends in a zero . Now remember second trick
30:33	with numbers bigger than 10 if it's odd or even
30:37	You can see on the end and ending is a
30:40	zero and every number that ends and zero is even
30:45	. Let's look at the chart again As you can
30:49	see 10 on the bottom ends in zero . And
30:54	it's even every single number that ends in zero is
30:58	even just like every number that ends in a one
31:01	is odd . Every number that ends in a two
31:04	is even . Every number that ends in a three
31:08	is odd because three is odd . Every number that
31:11	ends in a four is even and it goes on
31:14	and on , numbers that end in five are odd
31:17	, numbers that end in six or even numbers that
31:20	end in seven are odd . Yeah , Numbers that
31:26	end in eight are even numbers that end in nine
31:31	are odd and the numbers like 10 end in zero
31:35	are always even . So there you go odd .
31:40	And even as long as you learn these , you'll
31:44	know any number because the endings always tell you if
31:48	it's otter even . So once you know these ,
31:50	you'll know all of them , You're doing great .
31:56	You're increasing your skills just like this razor , you're
31:59	racing on the water , you're increasing your skills ,
32:02	you're doing a wonderful job . And next we are
32:06	going to learn about three dimensional shapes . This is
32:11	gonna be awesome . Love the three D shapes .
32:13	A lot of people know the two D shapes .
32:15	You might not know the three D shapes . You're
32:17	in the right place before we get started . Me
32:21	just dance here real quick . This is really cool
32:24	music . I really like this . You know ,
32:25	I like the dance . You know , some people
32:27	, they're not dancers , you know , I dance
32:29	, I dabble and dancing , you know ? All
32:33	right , that's enough . Can somebody turn that music
32:36	off ? Seriously ? I can I can't teach like
32:38	this . I can't teach with this music going on
32:41	. You know , I didn't feel like I'm in
32:42	a candy shop . Listen to some music off ,
32:44	please . Thanks . So here they are , our
32:49	old friends . The two D shapes . You're familiar
32:52	with these . You know , you're familiar with the
32:54	circle , the oval , the triangle , the pentagon
32:59	, the trapezoid , the hex a gone , the
33:02	square , the rectangle , the parallelogram in the octagon
33:07	. These are all our our shapes , R2D shapes
33:11	, you know , but these are old family friends
33:13	of ours . We don't want to just Forget about
33:16	these . And before we look at 3D shapes ,
33:18	it's really important for us to look at these shapes
33:21	again because these are old friends . So we're gonna
33:24	look at each one of these one by one just
33:26	to make sure you know who they are . Before
33:29	we learn all these new shapes . This first shape
33:34	doesn't even need an introduction . It's the circle ,
33:37	the circle that round figure . It's awesome . We
33:40	love this shape . It's one of the first ones
33:43	we ever learn the circle . This next shape is
33:48	one of the stretchy shapes . The oval , it's
33:51	like a circle got stretched out . Its elongated .
33:55	It's a tremendous shape . The oval , mm .
34:02	Mhm . Here's another familiar shape . The triangle .
34:06	Three sides . We love the triangle . The triangle
34:11	is great , The three sighted friend . Three sides
34:14	. A triangle . Wait , I keep saying we
34:19	love the shapes . I mean we like the shapes
34:22	. But do you love the shapes ? Do I
34:24	love the shapes ? I mean , I don't know
34:27	. I need to take it easy here . Uh
34:30	All right , let's keep going . Yeah . Ah
34:34	The square of four sides all equal . You know
34:38	, the square is good . The squares a good
34:40	shape . You know , sometimes you just need a
34:43	square . Sometimes you just need a square . Here's
34:49	the rectangle . The rectangle is longer than the square
34:54	because not all four sides are equal . The rectangle
35:00	. I know I'm we're in the middle of something
35:04	here , but I have to share this . Okay
35:05	, so what do you call a hamster with a
35:08	top hat ? Abraham stir Lincoln . I digress the
35:18	trapezoid . A cool shape with two of the sides
35:22	being parallel to each other and the parallelogram , another
35:25	four sided shape . Both pairs of sides are parallel
35:30	to each other and finally the pentagon with five sides
35:36	. The hex a gone with six sides and the
35:38	octagon with eight sides . What awesome shapes . So
35:48	let's go ahead and do a quick to D shaped
35:51	quiz . I need your help . I want to
35:53	see if you really learn these if you really know
35:56	these before we get into the three D . Shape
35:57	. So help me out here , we're gonna have
35:59	an awesome time . Wait what ? It's not my
36:05	birthday . Oh well what type of shape is on
36:09	the top ? Yeah . Yeah . A circle .
36:16	What type of shape is in the middle ? A
36:23	square , awesome . Okay now what shape is on
36:29	the bottom ? Of course A triangle , awesome job
36:36	. Now we've got more , this is a little
36:40	trickier . Which shape is in the middle ? Mhm
36:44	mm . Yeah . A trapezoid . Which shape is
36:50	on the right ? The pentagon . Good job .
36:57	And which shape is on the left ? Yeah ,
37:05	the square . Now try these . Which shape is
37:12	on the bottom ? Yeah , the oval . Which
37:19	shape is on the top ? Yeah , the parallelogram
37:28	. Which shape is in the middle . All right
37:35	. The rectangle . Great job . All right .
37:39	The last one which shape is on the left ?
37:48	Yeah , the hexagon which shape is on the right
37:58	. Great . The octagon and which shape is in
38:02	the middle , phenomenal ? The pentagon . Yeah .
38:10	All right . We're ready to learn the three D
38:13	shapes . We're going to learn how to identify the
38:16	three dimensional shapes . If you struggle through the quiz
38:19	, you might want to watch the first part of
38:21	the video again . Otherwise let's get started . So
38:26	as we're starting out it's important to remember what makes
38:30	a three D . Shape a three D . Shape
38:33	. There's an old rhyme that says three D shapes
38:36	are fat , not flat . And you can see
38:38	that with the sphere which is a three D .
38:41	Shape . We're about to learn and the circle ,
38:44	the circle is flat but the sphere is three D
38:49	. It's three Dimensional . All the shapes are like
38:52	that . So let's learn all these three D shapes
38:56	. So the first three D . Shape we're going
38:58	to learn is the sphere , the one that we
39:01	just mentioned . The sphere is the three D .
39:03	Version of the circle . It's perfectly round . There
39:12	are spheres all around us . One of the spheres
39:14	we see all the time . Our balls like this
39:17	soccer ball , a soccer ball is a sphere ,
39:21	it's perfectly round , it's a three D circle .
39:23	It's a sphere , you know this fear , Yes
39:27	, it's the Earth , it's where we live .
39:30	Our planet is a sphere . How cool is that
39:34	? Our own planet is a sphere perfectly round .
39:38	It's a sphere in this picture . We have two
39:43	spheres . Can you spot them ? Yeah , the
39:46	two spheres are the two bullying balls . Perfect round
39:52	spheres , spheres are all around us . Here we
39:57	have a group of three spheres and you can count
40:00	them right now . 123 spheres all together the shape
40:06	of a ball , a sphere perfectly round . Well
40:12	there you have it . The sphere . What a
40:14	cool three D shape to start with . Its round
40:17	there examples all around us and it's just so cool
40:21	. And you know what ? The three d shapes
40:23	are going to get even better . Our second three
40:28	D shape is the cone . The cone is a
40:31	really cool shape with a circle as the base or
40:35	the bottom . And it all comes up to one
40:38	point called a vertex . Here's an example of a
40:42	cone . I think we all love the ice cream
40:45	cone . If it doesn't have any ice cream inside
40:47	and you flipped it upside down , you'd be able
40:49	to see the circle base and it all comes up
40:52	to one point called the vertex . Here are two
40:57	cones , a red cone and a blue cone .
41:01	And you can see both cones have that circle basin
41:04	. All comes up to of vertex . What ?
41:07	Wonderful cones ? Yeah . Have you seen these before
41:12	? Their traffic cones here are many cones . I
41:17	didn't count all of them , but there's a lot
41:20	and they're wonderful wonderful cones . Yeah . So that's
41:25	our second three D shape . The kona wonderful cone
41:29	with the great circle base . It all comes up
41:32	to one point called the vertex . How awesome is
41:37	that ? Our third three D shape is the pyramid
41:41	. I love the pyramid . The pyramid is great
41:43	. It comes up to one point just like the
41:46	cone . Except the base is a square and the
41:48	sides instead of being smooth . They are triangles .
41:54	Okay like these are awesome . These are so cool
41:59	. The pyramids of Egypt , you see that they
42:01	have the triangle sides and the bottoms of these pyramids
42:06	are square . They're awesome examples of the pyramid .
42:09	This is a pretty cool pyramid . It's a decoration
42:12	that you plug into the wall but it's a great
42:14	example of what a pyramid looks like . The bottom
42:17	of the bases square . And there's the triangles on
42:21	the sides . How cool is this ? Here's another
42:26	pyramid and it's made of glass . There are so
42:29	many decorations and things around . Maybe even your house
42:33	that are shaped like a pyramid because pyramids look so
42:36	cool . People love putting them everywhere . There you
42:40	go . I mean , you know the pyramid ?
42:41	It's in good shape . You know , you see
42:42	a lot of them around . They've got the square
42:45	bottom or base and the triangles on the sides and
42:49	all goes up to a vertex . It's a classic
42:51	shape . It's pretty awesome . Our 4th 3D shape
42:57	is the cylinder . Now a cylinder is easy to
42:59	spot because it's got a circle on the top and
43:02	a circle on the bottom . And it's smooth all
43:06	around here we have a can of soup and it's
43:12	a cylinder has a circle on the top , a
43:15	circle on the bottom and it's smooth all around .
43:19	All cans and most jars are cylinders . Here we
43:24	have three cylinders . Their candles . And can I
43:27	tell you a secret ? Most candles are cylinders to
43:32	write this . This is just too crazy and too
43:37	awesome . Here are two more cylinders . Are you
43:41	kidding me ? Are you kidding me ? Even batteries
43:44	are cylinders , cylinders are seriously everywhere . A circle
43:48	on the top , a circle on the bottom and
43:51	smooth all around . I mean really ? The cylinder
43:55	is everywhere . I mean , you know the circle
43:58	on the top circle on the bottom , smooth all
44:00	around . I cylinder like what in the world do
44:03	you have to be everywhere ? Okay , the next
44:10	three D shape is the cube . The cube is
44:13	the three D version of the square . It has
44:16	six sides or faces that are all squares . Mm
44:22	hmm . Here we have two dice dice are in
44:27	the shape of a cube . So these two dice
44:30	or two cubes , they have six sides or faces
44:34	that are all squares . Here we have many cubes
44:41	. These are cubes that are made out of wood
44:44	. Each of them have six sides or faces that
44:48	are all squares . Here are seven cubes of ice
44:56	. Have you ever had a warm drink and you
44:58	need to put ice in it ? It's awesome because
45:00	it has this great shape , the shape of a
45:03	cube , six sides or faces all squares . I
45:08	mean there you go . The cube , right ?
45:11	The three D version of a square . And it's
45:14	got squares all along The sides , right there .
45:18	six sides or faces all squares . And I don't
45:21	know . I think it's pretty cool shape . Mm
45:26	Our final three D shape is the rectangular prism .
45:29	The rectangular prism is the three D version of the
45:32	rectangle . It has six sides or faces that are
45:36	all wrecked . Okay . An awesome example of the
45:40	rectangular prism are bricks and here we have four bricks
45:44	which are four rectangular prisms . The three D .
45:48	version of the Rectangle . You may have seen this
45:55	in your classroom or in your home . It's a
45:58	clean Xbox . And the clean Xbox is a great
46:01	example of the rectangular prism . It's got six sides
46:05	or faces that are all rectangles . Okay , so
46:08	the secret is , most boxes are rectangular prism .
46:13	So here's another rectangular prism and it's a box and
46:16	it's a shorter box , but it still has rectangles
46:19	all around . And it's rectangular prism . What else
46:25	can we say ? It's a cool shape . The
46:27	rectangular prism is the three D . Version of the
46:30	rectangle has six sides or faces that are all rectangles
46:34	. And it's just a neat shape to have around
46:37	, I think . I mean , you know .
46:39	Okay , so let's review . Pyramid , mm hmm
47:04	cylinders , mhm sphere , mhm cylinder cones . Yeah
47:33	. Pyramid , rectangular prism . Mhm . Mhm spheres
47:50	. Let's do some more On the top here .
47:56	We have cubes . We can tell that because it's
48:00	the 3D square . It has six sides or faces
48:04	. Each of them are squares . Is pretty cool
48:07	. Do you remember what shape these bricks are ?
48:10	Yeah , a rectangular prism . They are rectangular prisms
48:16	there . The 3D versions of the rectangle at the
48:24	top . We have a cone cone . It's got
48:29	a circle base on the bottom and all comes up
48:33	to one point called a vertex . Do you remember
48:37	the shape here on the bottom ? These are three
48:41	cylinders . They have a circle on the top and
48:45	a circle on the bottom . And it's smooth all
48:49	around . You're doing such an awesome job . Seriously
48:56	. So , cool . So , what's this top
48:58	shape , do you remember ? Yeah , it's a
49:01	pyramid . A pyramid . A pyramid has a square
49:04	base . It comes up to one vertex or one
49:07	point and has triangles as the sides . All right
49:16	. Do you remember this last shape here on the
49:18	bottom ? Yes . It's the sphere , the sphere
49:22	which is the three D . Circle . And we
49:25	started with it and we're ending with it and it's
49:27	so awesome . Hey Petey . I know , I
49:34	know I heard about your plane . You know it's
49:36	a cool plane . You know and and it's it's
49:39	neat . I don't know if it flies or you
49:41	you look pretty confident that it's gonna fly which is
49:44	cool . Yeah , I see you . Hello ?
49:48	Yeah thanks for waving . Thanks for saying hello .
49:50	You know we're actually in the middle of learning ,
49:52	we're in the middle of learning a lot of new
49:55	cool things right now . So I actually do have
49:58	to go high . You're still waving . Okay .
50:00	Um We're gonna go because now we need to learn
50:05	about roman numerals , which is a different way to
50:09	write numbers . And it was used a long time
50:12	ago in ancient Rome . And it's been used since
50:15	then . And you can think of it almost as
50:17	a secret code way of writing the numbers . It's
50:21	pretty simple to learn . And we're going to go
50:23	through that . The first roman numeral we're going to
50:28	learn is the roman numeral . I and I is
50:33	one I equals one . So if you see an
50:37	eye with the roman numeral , it's one . The
50:40	letter V . Is the roman numeral that means five
50:45	. And the letter X . Is the roman numeral
50:49	that means 10 . So when you think one it's
50:53	an eye , you think five , it's a V
50:57	. And if you think 10 it's an X .
51:02	So that's it . Just those three . I it
51:06	almost looks like a one . That's how you can
51:08	remember that . I is a one I . Is
51:12	the roman numeral for one . A V . Is
51:15	in the number five . When you spell it out
51:17	the number five , you see that right there .
51:19	It has a V . In it . So when
51:21	you think of V . You know oh you know
51:24	what ? There's a V . In the spelled out
51:28	number five . So the has to be five now
51:32	10 is exit , we can't think of anything that
51:36	could remind us of that . So there is no
51:38	memorization thing just when you see the exits 10 and
51:42	that's just what we're going to have to do .
51:45	Mhm . Okay , one last time here , I
51:47	just want to make sure you get it . There's
51:49	only three . I is the roman numeral for one
51:52	, the is the roman numeral for five and X
51:57	. Is the roman numeral for 10 . And you've
52:00	got to understand that so that we can start playing
52:02	kind of a game of putting them together And making
52:06	numbers other than just 15 and 10 . So let's
52:10	get started . So let's practice putting these Roman numerals
52:17	together . What number do you think this is two
52:22	? U . C . Two eyes and i is
52:26	one . So the answer is to two eyes is
52:32	the number 21 What about this one ? You what
52:41	number do you think this is why there are three
52:46	eyes ? Yeah it's the number three . The let's
52:54	try this one . What number do you think this
52:57	is ? We see two X . Is an X
53:04	equals 10 . So 10 plus 10 equals 20 .
53:10	Great job . This is the number 20 . Whoa
53:19	. This one is so cool . Okay . An
53:22	X . And A V . What number do you
53:24	think ? This is A A . The X .
53:30	Is a 10 V . Is what number five ,
53:36	awesome . So what is 10 plus five ? 15
53:44	. Whoa . Thanks so much for helping out now
53:49	that we've looked at how to put some of these
53:51	together . I want to tell you about two special
53:54	numerals that are a little bit different . And so
53:57	you're gonna have to just remember these on their own
54:00	. The first is the number four and the number
54:02	four is represented with an I . And V .
54:06	And eyes before the V . Because four is one
54:10	less than five which is V . So remember with
54:14	four its I . V . With nine similar except
54:20	with the X . Nine is I . X .
54:23	X . Is 10 and I is just before it
54:26	. So nine is I . X . Okay .
54:31	That was really cool . Thanks for hanging out and
54:34	learning those with me . But we're not done .
54:36	We want to go through all the numbers up to
54:39	30 just using the numerals and I want to see
54:42	how much you've really learned . So if you'll do
54:45	me a favor as the numerals go up , I
54:48	want you to say the numbers along with me and
54:52	we can practice together . Sound good . Alright ,
54:55	let's get started . One two 34 five , sex
55:12	seven eight nine 10 11 . Mhm . 12 13
55:27	, 14 15 , 16 , 17 , 18 ,
55:38	19 , 20 21 22 23 24 25 26 ,
55:52	27 28 29 and 30 . Mhm . Well there
