Making Teen Numbers with Tens and Ones
00:00:06.980 --> 00:00:16.620
In this video, we will learn how to decompose or break apart the numbers 11 to 19 into a ten and some ones.
00:00:17.920 --> 00:00:39.930
Here are the numbers 11 to 19: 11, 12, 13, 14, 15, 16, 17, 18, 19.
00:00:41.440 --> 00:00:45.840
We can make teen numbers from a ten and some ones.
00:00:47.120 --> 00:00:48.310
This is a ten frame.
00:00:48.770 --> 00:00:50.190
It’s full of counters.
00:00:50.220 --> 00:00:52.240
So, there are 10 counters.
00:00:53.020 --> 00:00:55.050
We can call this a ten.
00:00:56.610 --> 00:00:59.580
We can call these counters ones.
00:01:00.510 --> 00:01:03.780
We have a ten and a one.
00:01:05.010 --> 00:01:08.900
10 and one more is 11.
00:01:09.980 --> 00:01:15.570
We can decompose the number 11 or break it into two parts.
00:01:16.520 --> 00:01:19.200
11 has a ten and a one.
00:01:21.080 --> 00:01:25.580
We can break number 12 into a ten and two ones.
00:01:26.490 --> 00:01:42.010
10 and three ones makes 13, 14, 15, 16, 17, 18, 19.
00:01:44.160 --> 00:01:47.250
Sophia used base ten blocks to make a number.
00:01:48.400 --> 00:01:50.120
How many ones are there?
00:01:51.500 --> 00:01:52.710
What is the number?
00:01:54.420 --> 00:01:58.150
We know Sophia has used base ten blocks to make a number.
00:01:59.670 --> 00:02:01.280
She has one ten.
00:02:02.790 --> 00:02:04.510
How many ones are there?
00:02:05.750 --> 00:02:06.760
Let’s count.
00:02:07.340 --> 00:02:14.260
One, two, three, four, five, six, seven, eight.
00:02:15.840 --> 00:02:17.160
What is the number?
00:02:18.410 --> 00:02:22.000
We have one ten and eight ones.
00:02:23.180 --> 00:02:26.870
10 and eight more is 18.
00:02:28.470 --> 00:02:31.270
Sophia’s number is number 18.
00:02:34.370 --> 00:02:38.170
Decompose this number to complete the number bond.
00:02:39.940 --> 00:02:45.820
We have to decompose or break apart this number to complete the part whole model.
00:02:47.060 --> 00:02:49.740
We know the number is number 16.
00:02:51.170 --> 00:02:55.740
16 is 10 and some ones.
00:02:56.580 --> 00:02:59.180
We have to work out how many ones.
00:03:00.190 --> 00:03:01.410
Here’s our 10.
00:03:02.450 --> 00:03:05.640
Let’s add ones until we reach 16.
00:03:06.900 --> 00:03:18.510
11, 12, 13, 14, 15, 16.
00:03:20.160 --> 00:03:22.780
We’ve added six ones.
00:03:23.790 --> 00:03:27.520
A ten and six ones makes 16.
00:03:28.730 --> 00:03:31.010
The missing number is number six.
00:03:32.660 --> 00:03:37.590
We broke apart the number 16 into a ten and six ones.
00:03:40.370 --> 00:03:52.040
Look at how Sophia has made the number 13 from tens and ones. 13 is one ten and three ones.
00:03:54.350 --> 00:03:56.460
13 is one ten and three ones.
00:03:56.460 --> 00:04:00.090
What number does this table show?
00:04:00.090 --> 00:04:04.990
The table is called a place value table.
00:04:04.990 --> 00:04:07.880
It shows the number of tens and ones in our number.
00:04:09.400 --> 00:04:10.820
Our number has a ten.
00:04:11.930 --> 00:04:13.350
Let’s count the ones.
00:04:14.650 --> 00:04:21.050
There are one, two, three, four, five, six.
00:04:21.820 --> 00:04:25.620
Our number has a ten and six ones.
00:04:26.880 --> 00:04:29.640
Let’s count forward six from number 10.
00:04:31.630 --> 00:04:42.960
11, 12, 13, 14, 15, 16.
00:04:44.310 --> 00:04:48.170
A ten and six ones makes the number 16.
00:04:49.720 --> 00:04:52.550
The table shows the number 16.
00:04:53.800 --> 00:04:55.610
What have we learned in this video?
00:04:57.140 --> 00:05:04.960
We’ve learned how to decompose or break apart the numbers 11 to 19 into a ten and some ones.
