WEBVTT 00:00:00.470 --> 00:00:01.660 - What we're going to do in this video 00:00:01.660 --> 00:00:04.800 is get some practice writing reasonably large numbers 00:00:04.800 --> 00:00:06.850 in different ways. 00:00:06.850 --> 00:00:09.920 So, for example, let's say we had this number 00:00:09.920 --> 00:00:12.570 and I'm going to not say it out loud on purpose. 00:00:12.570 --> 00:00:15.723 So, this number right over here. 00:00:16.600 --> 00:00:18.090 What I wanna do is think 00:00:18.090 --> 00:00:21.130 about how would I write this out in words? 00:00:21.130 --> 00:00:22.970 And I encourage you to pause this video 00:00:22.970 --> 00:00:24.720 and try to figure that out on your own 00:00:24.720 --> 00:00:25.610 before we do it together. 00:00:25.610 --> 00:00:28.110 And if you take out paper and actually write this out, 00:00:28.110 --> 00:00:29.823 how would you write this number? 00:00:31.080 --> 00:00:33.150 Well now, we can do it together. 00:00:33.150 --> 00:00:35.220 Actually before I even write it out in words, 00:00:35.220 --> 00:00:37.700 I'll write this out in a place value table 00:00:37.700 --> 00:00:39.350 'cause it might help us, or it just helps us 00:00:39.350 --> 00:00:42.910 break down exactly what this number represents. 00:00:42.910 --> 00:00:45.310 So, just as a bit of a refresher, 00:00:45.310 --> 00:00:47.960 if you're not familiar with place value tables. 00:00:47.960 --> 00:00:50.660 You think of a column for the different place values 00:00:50.660 --> 00:00:52.210 and here we're going from the ones place 00:00:52.210 --> 00:00:55.390 all the way to 10s, 1,000s, 10,000s, 00:00:55.390 --> 00:00:57.734 so we're going to have a 10,0000s 00:00:57.734 --> 00:00:59.456 place right over here. 00:00:59.456 --> 00:01:03.930 We're going to have a 1,000s place right over here. 00:01:03.930 --> 00:01:07.110 This is just an S here, so ten thousands, one thousands. 00:01:07.110 --> 00:01:08.760 Sometimes you'll see it written out. 00:01:08.760 --> 00:01:12.045 This is the 100s place. 00:01:12.045 --> 00:01:15.280 This is the 10s place. 00:01:15.280 --> 00:01:17.650 And this is the ones place. 00:01:17.650 --> 00:01:20.710 And so, how many 10,000s do we have? 00:01:20.710 --> 00:01:22.300 Actually, let's start at the ones place. 00:01:22.300 --> 00:01:23.580 How many ones do we have? 00:01:23.580 --> 00:01:24.413 We see it right here. 00:01:24.413 --> 00:01:26.720 We have five ones. 00:01:26.720 --> 00:01:28.220 How many 10s do we have? 00:01:28.220 --> 00:01:29.053 We see it right there, 00:01:29.053 --> 00:01:31.610 actually, we have zero 10s. 00:01:31.610 --> 00:01:34.280 How many 100s do we have? 00:01:34.280 --> 00:01:36.930 We see it right there, six 100s. 00:01:36.930 --> 00:01:38.610 How many 1,000s? 00:01:38.610 --> 00:01:39.837 We go to the 1,000s place 00:01:39.837 --> 00:01:42.160 and we see we have two 1,000s. 00:01:42.160 --> 00:01:45.460 And then, how many 10,000s we have? 00:01:45.460 --> 00:01:46.390 Well, we see right there, 00:01:46.390 --> 00:01:48.510 we have eight 10,000s. 00:01:48.510 --> 00:01:50.660 So now that we have this representation, 00:01:50.660 --> 00:01:51.493 let's write it out in words 00:01:51.493 --> 00:01:53.030 and you don't have to do this every time, 00:01:53.030 --> 00:01:54.380 but I am just trying to make sure we see 00:01:54.380 --> 00:01:57.200 every possible way of thinking about it. 00:01:57.200 --> 00:01:59.698 So, you could say eight 10s, 00:01:59.698 --> 00:02:04.140 two 1,000s, six 100s, and five ones, 00:02:04.140 --> 00:02:07.260 but that's not exactly how people would say it out in words. 00:02:07.260 --> 00:02:09.180 What is typical is that people would say 00:02:09.180 --> 00:02:14.040 82 1,000s, 600 and five. 00:02:14.040 --> 00:02:15.790 And so I'm gonna write it that way. 00:02:15.790 --> 00:02:17.490 And when you write it out in words, 00:02:17.490 --> 00:02:19.900 the standard way of doing it is actually put commas 00:02:19.900 --> 00:02:22.000 wherever you put the commas in, 00:02:22.000 --> 00:02:24.430 this is right over here written in standard form. 00:02:24.430 --> 00:02:27.240 So what we would do is, we would express this part 00:02:27.240 --> 00:02:30.310 right over here as eighty-two thousand, 00:02:30.310 --> 00:02:31.850 so let me write it out. 00:02:31.850 --> 00:02:33.537 Eighty two thousand. 00:02:42.330 --> 00:02:45.400 And then, put this comma there. 00:02:45.400 --> 00:02:47.260 Eighty two thousand, comma, 00:02:47.260 --> 00:02:50.940 and then we have 600 and then we have no 10s, 00:02:50.940 --> 00:02:52.430 so it's 605. 00:02:52.430 --> 00:02:53.800 If there was a one 10 here, 00:02:53.800 --> 00:02:55.100 then it would have been 615, 00:02:55.100 --> 00:02:56.820 but this is just 605. 00:02:56.820 --> 00:02:59.980 And so I will do it in a different color. 00:02:59.980 --> 00:03:01.730 Let's do it in this blue color. 00:03:01.730 --> 00:03:06.730 So eighty-two thousand, and then six hundred five. 00:03:10.560 --> 00:03:11.810 And we're done! 00:03:11.810 --> 00:03:13.433 Let's do another example. 00:03:14.670 --> 00:03:16.770 So now I'm gonna write out a number in words 00:03:16.770 --> 00:03:18.340 and I want you to write it in standard form. 00:03:18.340 --> 00:03:22.983 So, the number is fifty thousand, six hundred thirty-one. 00:03:35.310 --> 00:03:38.240 And I want you to write this in standard form. 00:03:38.240 --> 00:03:40.120 So it's really just write it out as a number 00:03:40.120 --> 00:03:41.810 and put commas in the appropriate places. 00:03:41.810 --> 00:03:44.073 Pause this video and see if you can do that. 00:03:44.980 --> 00:03:47.190 All right, now let's do it together. 00:03:47.190 --> 00:03:51.120 So, this first part, fifty thousand, 00:03:51.120 --> 00:03:53.420 well, we could just write that as, 00:03:53.420 --> 00:03:55.150 actually, let's put the place values out here, 00:03:55.150 --> 00:03:56.621 so there's a 10,000s place, 00:03:56.621 --> 00:04:00.843 this is a 1,000s place, 100s, 10s, and ones. 00:04:00.843 --> 00:04:02.493 So, fifty thousand, so 50 1,000s, 00:04:04.080 --> 00:04:05.350 you could write like this, 00:04:05.350 --> 00:04:07.430 you could say that's five 10,000s, 00:04:07.430 --> 00:04:09.849 or you could say this is 50 1,000s. 00:04:09.849 --> 00:04:13.830 Then they say six hundred thirty-one. 00:04:13.830 --> 00:04:18.410 So, six hundred, well that's six 100s right over here 00:04:18.410 --> 00:04:23.220 and then thirty-one, that is thirty and one, 00:04:23.220 --> 00:04:25.700 or three 10s and one one, 00:04:25.700 --> 00:04:28.930 three 10s and one one, or 31. 00:04:28.930 --> 00:04:31.240 And of course, you wanna put your comma 00:04:31.240 --> 00:04:33.840 in the same place, and you put your comma 00:04:33.840 --> 00:04:36.360 every three places, so the first time you do it, 00:04:36.360 --> 00:04:37.860 if you're moving from the right, 00:04:37.860 --> 00:04:42.180 you put it between the 100s and the 1,000s place. 00:04:42.180 --> 00:04:43.013 So, there you have it. 00:04:43.013 --> 00:04:47.623 This is the same thing as 50,631. 00:04:49.080 --> 00:04:52.593 This is that number written in stand form.
