00:00:01.800 --> 00:00:05.050
Counting Objects up to 10
00:00:06.240 --> 00:00:10.380
In this video, we’re going to practice counting up to 10 objects.
00:00:10.930 --> 00:00:18.430
And we’re going to learn that the number of objects doesn’t change even if they’re arranged in different ways.
00:00:20.680 --> 00:00:21.910
Here are some birds.
00:00:22.790 --> 00:00:25.950
They’re standing in a line balancing on a wire.
00:00:26.920 --> 00:00:28.120
How many birds are there?
00:00:28.960 --> 00:00:36.850
One, two, three, four, five, six, seven.
00:00:37.430 --> 00:00:43.250
There are seven birds, and we could represent our seven birds by using seven counters in a line.
00:00:43.970 --> 00:00:48.420
Now, let’s imagine that the same birds fly off making a circle shape.
00:00:49.060 --> 00:00:50.470
How many birds are there now?
00:00:51.110 --> 00:00:58.100
One, two, three, four, five, six, seven.
00:00:58.730 --> 00:01:04.570
Even though the arrangement or the position of the birds is different, the number is still the same.
00:01:05.090 --> 00:01:07.960
We can show seven in many different ways.
00:01:08.500 --> 00:01:12.080
Now, let’s practice counting some objects in different arrangements.
00:01:14.380 --> 00:01:16.090
How many cats are there?
00:01:16.960 --> 00:01:23.390
The cats in this problem are standing in a line, and we’re being asked how many are there.
00:01:24.100 --> 00:01:26.270
We need to count the cats.
00:01:26.880 --> 00:01:29.740
We could use a 10-frame and counters to help us.
00:01:30.350 --> 00:01:35.030
To start with, let’s put one counter underneath each cat.
00:01:35.650 --> 00:01:38.930
We know we have the same number of counters as cats.
00:01:39.740 --> 00:01:42.940
Now, let’s move each counter onto the 10-frame.
00:01:43.400 --> 00:01:45.770
And as we do so, let’s count them.
00:01:46.460 --> 00:01:58.980
One, two, three, four, five, six, seven, eight, nine, 10.
00:01:59.690 --> 00:02:03.030
There are 10 counters, and our 10-frame is full.
00:02:03.820 --> 00:02:06.710
We’ve counted the number of cats using counters.
00:02:07.290 --> 00:02:08.630
How many cats are there?
00:02:09.460 --> 00:02:11.380
There are 10 cats.
00:02:13.220 --> 00:02:15.130
Let’s practice counting more objects.
00:02:17.070 --> 00:02:21.300
How many stars are found in the flag of Singapore?
00:02:23.070 --> 00:02:27.390
Singapore is a country, and this is what its flag looks like.
00:02:27.920 --> 00:02:32.010
It’s made up of a moon shape or a crescent and some stars.
00:02:32.800 --> 00:02:35.520
We’re asked, how many stars are there?
00:02:36.450 --> 00:02:39.970
The stars are in a circle arrangement or pattern.
00:02:40.950 --> 00:02:46.680
To help us remember which stars we’ve counted, why don’t we draw rings around them as we say each number?
00:02:47.390 --> 00:02:48.920
We’ll start counting at the top.
00:02:49.040 --> 00:02:54.900
One, two, three, four, five.
00:02:55.540 --> 00:02:58.280
We’ve counted five stars.
00:03:00.040 --> 00:03:03.760
The flag of Singapore shows five stars.
00:03:06.490 --> 00:03:10.750
The objects in our next question make a rectangular shape, but we can still count them.
00:03:12.880 --> 00:03:14.620
How many umbrellas are there?
00:03:15.480 --> 00:03:20.490
To answer a question that asked us how many, we need to count.
00:03:21.120 --> 00:03:23.960
And we’ve been given a picture of some umbrellas to count.
00:03:25.150 --> 00:03:27.540
How could we make sure we count each umbrella?
00:03:28.040 --> 00:03:31.550
We could start by putting a cube next to each umbrella.
00:03:32.450 --> 00:03:33.060
There we go.
00:03:33.630 --> 00:03:40.540
There are the same number of cubes as there are umbrellas, so all we need to do is to count the cubes.
00:03:41.220 --> 00:03:54.420
One, two, three, four — that’s the top row done, let’s carry on counting — five, six, seven, eight.
00:03:54.990 --> 00:03:57.310
So, we know there are eight umbrellas.
00:03:58.590 --> 00:04:03.410
The cubes are in a tall tower and the umbrellas are making a rectangle shape.
00:04:04.230 --> 00:04:07.040
But both arrangements show the number eight.
00:04:07.830 --> 00:04:10.920
We can show the same number in different ways.
00:04:11.890 --> 00:04:16.490
We’ve counted the umbrellas and we can say there are eight.
00:04:19.650 --> 00:04:22.390
The objects in this question were in nice neat patterns.
00:04:23.120 --> 00:04:26.460
But what if they’re all jumbled up and not really making a pattern at all?
00:04:26.810 --> 00:04:28.100
Can we still count them?
00:04:28.970 --> 00:04:29.670
Let’s try.
00:04:31.500 --> 00:04:35.040
Count the jewels aloud, and then write the number.
00:04:36.180 --> 00:04:39.120
In the picture, we can see some shiny jewels.
00:04:39.780 --> 00:04:43.870
Now, they’re not making a nice neat line, but this doesn’t matter.
00:04:43.870 --> 00:04:45.090
We can still count them.
00:04:46.160 --> 00:04:49.680
In the question, we’re asked to count the jewels aloud.
00:04:50.270 --> 00:04:52.910
And then once we finish, we need to write the number.
00:04:54.030 --> 00:04:57.270
Let’s point to each jewel and say each number out loud.
00:04:57.750 --> 00:05:00.090
And as you watch the video, count aloud too.
00:05:01.110 --> 00:05:13.410
One, two, three, four, five, six, seven.
00:05:14.200 --> 00:05:17.870
We’ve counted the jewels, and there are seven of them.
00:05:18.590 --> 00:05:21.520
So to answer the question, we need to complete the second part.
00:05:21.860 --> 00:05:23.610
We need to write the number seven.
00:05:24.380 --> 00:05:27.170
And the number seven looks like this.
00:05:27.930 --> 00:05:32.980
We counted the jewels out loud, and then we’ve written the number to represent how many there are.
00:05:33.930 --> 00:05:36.080
There are seven jewels.
00:05:37.790 --> 00:05:40.130
We’ve counted objects in all sorts of shapes.
00:05:40.950 --> 00:05:47.280
In our final example, let’s see how we can represent the same number in different ways.
00:05:49.520 --> 00:05:51.070
Count the red cubes.
00:05:52.390 --> 00:05:56.650
Which set of cubes has the same number as set A?
00:05:56.650 --> 00:06:05.000
In the first picture, we can see a line of red cubes, and they’re labelled set A.
00:06:05.920 --> 00:06:08.590
We’re asked to count the red cubes.
00:06:09.410 --> 00:06:10.320
How many are there?
00:06:11.660 --> 00:06:24.320
One, two, three, four, five, six, seven.
00:06:25.230 --> 00:06:27.300
There are seven red cubes.
00:06:28.130 --> 00:06:33.120
Now, we’re given three more sets of cubes to look at, this time they’re yellow cubes.
00:06:33.920 --> 00:06:39.610
And we’re asked, which set of cubes has the same number as set A?
00:06:40.810 --> 00:06:43.700
Well, if we look at our cubes, they look different.
00:06:44.870 --> 00:06:46.740
For a start, they’re not red; they’re yellow.
00:06:47.190 --> 00:06:48.480
And they’re not in a line.
00:06:48.990 --> 00:06:50.110
They’re all jumbled up.
00:06:50.900 --> 00:06:52.970
None of them look the same as set A.
00:06:54.050 --> 00:06:59.600
But we know different arrangements of objects can still show the same number.
00:07:00.590 --> 00:07:06.910
Let’s count our sets of yellow cubes until we find one that has seven cubes just like the red.
00:07:07.510 --> 00:07:08.960
Let’s count the first set to begin with.
00:07:09.460 --> 00:07:21.880
One, two, three, four, five, six, seven, eight.
00:07:22.300 --> 00:07:24.240
We’re looking for a set of seven cubes.
00:07:24.500 --> 00:07:25.910
So, this answer is not right.
00:07:26.810 --> 00:07:28.310
Let’s count our second set.
00:07:29.130 --> 00:07:38.030
One, two, three, four, five, six, seven.
00:07:38.630 --> 00:07:42.170
This set of cubes has the same number as set A.
00:07:42.710 --> 00:07:44.610
Let’s count the final set just to check.
00:07:44.720 --> 00:07:55.990
One, two, three, four, five, six, seven — oh this is going to be more than seven — eight, nine.
00:07:56.750 --> 00:07:59.340
We counted seven red cubes.
00:07:59.870 --> 00:08:04.350
And we know that it doesn’t matter how cubes are arranged or even what color they are.
00:08:04.850 --> 00:08:08.290
We can still show the same number in a different way.
00:08:08.890 --> 00:08:16.690
And so, the set of yellow cubes that has the same number as set A is the one that contains seven cubes.
00:08:21.170 --> 00:08:22.710
Well, what have we learned in this video?
00:08:23.360 --> 00:08:27.360
Well, firstly, we’ve learned to count up to 10 objects.
00:08:28.240 --> 00:08:30.140
We’ve had lots of practice at doing this.
00:08:30.820 --> 00:08:41.500
We’ve also learned that even if we change the arrangement of the same number of objects, the number stays the same.
