Emma thinks that the number in Group C is greater than the number in Group D.
00:00:08.157 --> 00:00:10.707
Is this true or false?
00:00:12.417 --> 00:00:15.917
Let’s start by looking at the number in Group C.
00:00:17.497 --> 00:00:19.977
How many tens does this number have?
00:00:21.607 --> 00:00:23.037
It just has one ten.
00:00:24.237 --> 00:00:27.657
So we can write a one in the tens column.
00:00:28.957 --> 00:00:31.167
How many ones does this number have?
00:00:33.057 --> 00:00:36.967
One, two, three, four, five.
00:00:38.297 --> 00:00:41.297
So we can write a five in the ones column.
00:00:42.477 --> 00:00:45.827
The number in Group C is the number 15.
00:00:46.337 --> 00:00:49.327
One ten and five ones makes 15.
00:00:50.767 --> 00:00:53.117
Now, let’s look at the number in Group D.
00:00:54.267 --> 00:00:56.347
How many tens does this number have?
00:00:57.627 --> 00:00:59.007
There are two tens.
00:01:00.657 --> 00:01:02.167
Now, let’s count the ones.
00:01:02.557 --> 00:01:06.187
One, two, three, four, five.
00:01:07.277 --> 00:01:09.267
Both numbers have five ones.
00:01:11.147 --> 00:01:14.347
The number in Group D is the number 25.
00:01:14.767 --> 00:01:18.327
Two tens and five ones makes 25.
00:01:20.007 --> 00:01:27.527
Emma thinks that the number in Group C, which is 15, is greater than the number in Group D, which is 25.
00:01:28.577 --> 00:01:29.747
Is she correct?
00:01:31.327 --> 00:01:34.567
Is 15 greater than 25?
00:01:36.067 --> 00:01:44.687
One ten is less than two tens, so the number 15 is less than 25.
00:01:46.157 --> 00:01:48.397
Emma’s statement is false.
00:01:50.277 --> 00:01:53.187
15 isn’t greater than 25.
00:01:53.227 --> 00:01:54.977
It’s less than 25.
00:01:55.897 --> 00:01:58.107
The correct answer is “false.”
