00:00:01.490 --> 00:00:03.570
We can count in hundreds.
00:00:04.760 --> 00:00:11.790
100, 200, 300, 400, what?
00:00:13.190 --> 00:00:15.940
Write the missing number in words.
00:00:16.750 --> 00:00:19.690
And, write the missing number in digits.
00:00:21.220 --> 00:00:25.940
Each of the blue blocks in this question represents 100.
00:00:26.650 --> 00:00:33.880
We can tell this because there’s only one block in the first column, and it’s labeled with the number 100.
00:00:35.030 --> 00:00:38.980
So, we can use these 100-blocks to help us count in hundreds.
00:00:39.830 --> 00:00:42.770
Look at how we add one more block each time.
00:00:43.510 --> 00:00:46.280
To start with, we have one block.
00:00:48.030 --> 00:00:52.570
Then, it becomes two and then three.
00:00:53.970 --> 00:00:57.440
We keep on adding one more 100 each time.
00:00:58.780 --> 00:01:03.520
And so, every column is 100 larger than the last one.
00:01:05.360 --> 00:01:07.950
The final column isn’t labeled.
00:01:08.750 --> 00:01:15.180
Let’s count in hundreds from the start to see if we can work out what the final column should be worth.
00:01:16.110 --> 00:01:23.950
100, 200, 300, 400.
00:01:25.030 --> 00:01:29.800
We go from 400 to having one more 100 in the last column.
00:01:30.390 --> 00:01:32.820
We have five 100s.
00:01:33.710 --> 00:01:36.480
The missing number is 500.
00:01:37.480 --> 00:01:41.720
There are five blocks and each one is worth 100.
00:01:42.480 --> 00:01:45.080
Altogether that’s 500.
00:01:46.230 --> 00:01:50.330
Now that we know our missing number is 500, we can answer the question.
00:01:50.630 --> 00:01:54.880
First, we’re told to write the missing number in words.
00:01:55.600 --> 00:02:00.720
And to do this, we write the number five as a word, F-I-V-E.
00:02:01.480 --> 00:02:02.950
And then, the word hundred.
00:02:04.200 --> 00:02:07.030
Five hundred.
00:02:07.970 --> 00:02:12.130
Secondly, we’re asked to write the missing number in digits.
00:02:12.680 --> 00:02:16.810
We can see the numbers from 100 to 400 already written in digits.
00:02:17.820 --> 00:02:24.450
To write the number 500, we simply need to make sure that the digit five is in the hundreds place.
00:02:26.000 --> 00:02:32.580
And to show that it is in the hundred place, we need to put a zero in the tens place and a zero in the ones place too.
00:02:33.960 --> 00:02:44.030
So to write the missing number, which we said was 500, in digits, we have to write the digit five, zero, zero.
00:02:45.170 --> 00:02:47.380
This is the same as 500.
00:02:48.290 --> 00:02:51.600
We counted in hundreds to help us find the missing number.
00:02:52.280 --> 00:02:57.410
100, 200, 300, 400, 500.
00:02:58.150 --> 00:03:03.960
We write the missing number in words with the words five followed by hundred.
00:03:05.180 --> 00:03:11.320
And, we write the missing number in digits with the digits five, zero, zero.
