00:00:03.050 --> 00:00:09.100
Jennifer and David are representing numbers with base ten blocks and digits.
00:00:10.470 --> 00:00:12.600
Have they represented the same number?
00:00:14.160 --> 00:00:17.830
Write the number represented by the blocks in unit form.
00:00:19.070 --> 00:00:21.950
What is the tens digit in Jennifer’s number?
00:00:23.790 --> 00:00:27.950
Here are Jennifer’s blocks and David’s number.
00:00:29.160 --> 00:00:33.770
The first part of the question asks us if they’ve represented the same number.
00:00:35.180 --> 00:00:38.770
Jennifer has used base ten blocks to represent the number.
00:00:40.000 --> 00:00:46.150
The blue base ten blocks represent 100, and there are three.
00:00:46.430 --> 00:00:50.070
So we know that Jennifer’s number has three hundreds.
00:00:51.440 --> 00:00:58.720
The pink blocks represent the number of ones in Jennifer’s number; there are six.
00:00:59.800 --> 00:01:03.690
And Jennifer’s number has no tens blocks.
00:01:05.380 --> 00:01:12.850
David’s number is number 36 which has three tens and six ones.
00:01:14.570 --> 00:01:19.170
The answer to the question have they represented the same number is no.
00:01:20.830 --> 00:01:24.130
Jennifer’s number is number 306.
00:01:25.150 --> 00:01:28.480
David’s number is number 36.
00:01:29.580 --> 00:01:36.430
The next part of the question asks us to write the number represented by the blocks in unit form.
00:01:37.700 --> 00:01:43.790
The number represented by the blocks is Jennifer’s number, 306.
00:01:45.010 --> 00:01:54.270
306 has three hundreds and six ones.
00:01:58.370 --> 00:02:04.210
And the final part of the question asks us what is the tens digit in Jennifer’s number.
00:02:06.760 --> 00:02:09.430
There are no tens in Jennifer’s number.
00:02:10.330 --> 00:02:13.760
So the tens digit is zero.
00:02:15.030 --> 00:02:19.790
Jennifer and David represented numbers with base ten blocks and digits.
00:02:20.770 --> 00:02:25.410
The number represented by Jennifer’s blocks was the number 306.
00:02:26.240 --> 00:02:31.330
And the number represented in digits by David was 36.
00:02:32.230 --> 00:02:36.320
So the answer to the question have they represented the same number is no.
00:02:37.780 --> 00:02:39.200
The numbers are different.
00:02:40.480 --> 00:02:48.170
The number represented by blocks in unit form is three hundreds and six ones.
00:02:49.220 --> 00:02:52.900
And the tens digit in Jennifer’s number is zero.
00:02:54.460 --> 00:03:02.800
Although Jennifer and David used some of the same digits, Jennifer’s number had a zero in the tens place.
