00:00:01.350 --> 00:00:02.560
Picture Graphs
00:00:03.880 --> 00:00:12.500
In this video, we will learn how to read picture graphs to find how many items are in a category or group.
00:00:13.690 --> 00:00:21.270
And we will learn how to find out which category or group has the most or least items.
00:00:21.980 --> 00:00:27.610
This is a picture graph, at sometimes called a pictogram.
00:00:28.920 --> 00:00:35.170
A picture graph or a pictogram shows us information using pictures.
00:00:36.840 --> 00:00:42.100
In this picture graph, the pictures we’re shown are stick people.
00:00:43.200 --> 00:00:47.240
Each stick person represents one person.
00:00:48.530 --> 00:00:51.510
We count one for each stick person.
00:00:52.550 --> 00:00:57.170
The picture graph is showing us the games that children like to play in the playground.
00:00:58.070 --> 00:01:05.430
Some children like to play with the skipping rope, and other children like to play with the ball.
00:01:06.600 --> 00:01:10.000
We call these the categories in the picture graph.
00:01:10.430 --> 00:01:13.930
Rope is a category and ball is a category.
00:01:14.910 --> 00:01:17.750
How many children are playing with the skipping rope?
00:01:19.240 --> 00:01:26.810
If each stick person represents one person, we just need to count the number of stick people.
00:01:27.630 --> 00:01:32.140
In other words, we need to count the number of pictures in this category.
00:01:33.490 --> 00:01:41.330
One, two, three, four.
00:01:43.340 --> 00:01:47.190
There are four pictures in the rope category.
00:01:47.710 --> 00:01:50.350
Four children are playing with the skipping rope.
00:01:51.810 --> 00:01:53.910
How many children are playing with the ball?
00:01:54.540 --> 00:01:56.320
Can you count the pictures?
00:01:57.690 --> 00:01:58.670
There are two.
00:02:00.130 --> 00:02:02.890
We know that four is more than two.
00:02:04.100 --> 00:02:11.300
So, we can say that playing with the skipping rope is more popular than playing with the ball.
00:02:12.550 --> 00:02:16.200
More children like playing skipping rope than playing ball.
00:02:17.790 --> 00:02:23.750
So, we’ve learned that a picture graph or a pictogram uses pictures to show information.
00:02:24.930 --> 00:02:33.120
Let’s try some questions now to help us practice reading information in picture graphs or pictograms.
00:02:35.740 --> 00:02:40.730
Benjamin made a picture graph to show how many children came to the after-school club.
00:02:42.140 --> 00:02:51.030
The number of boys is more than, less than, or the same as the number of girls.
00:02:52.900 --> 00:02:56.050
We have to complete this sentence.
00:02:57.920 --> 00:03:09.130
We need to use the information shown in the picture graph to work out if the number of boys is more, less, or the same as the number of girls.
00:03:10.350 --> 00:03:15.020
The picture graph shows us how many children are in the after-school club.
00:03:16.020 --> 00:03:21.350
It has two categories, boys and girls.
00:03:22.620 --> 00:03:26.810
And we’re told that each picture of a smiley face stands for one child.
00:03:29.180 --> 00:03:32.570
How many smiley-face pictures are there in the boys’ category?
00:03:33.830 --> 00:03:41.120
One, two, three, four.
00:03:42.340 --> 00:03:54.760
Now, we know there are four boys in the after-school club, and there are one, two, three, four girls in the after-school club.
00:03:55.810 --> 00:04:03.800
The number of boys is the same as the number of girls, four boys and four girls.
00:04:05.270 --> 00:04:08.830
We read the information in the picture graph.
00:04:09.540 --> 00:04:13.280
We compared the number of boys and the number of girls.
00:04:13.610 --> 00:04:20.060
And we found that the number of boys is the same as the number of girls.
00:04:22.350 --> 00:04:26.350
Mason asked his class to choose what they usually ate for breakfast.
00:04:27.530 --> 00:04:31.120
What do most students eat for breakfast?
00:04:31.650 --> 00:04:35.520
Fruit, toast, or eggs.
00:04:37.180 --> 00:04:39.950
How many students eat fruit?
00:04:41.270 --> 00:04:44.880
How many more students eat toast than fruit?
00:04:46.170 --> 00:04:55.740
We know that Mason has asked his class what they eat for breakfast: fruit, eggs, or toast.
00:04:56.600 --> 00:05:01.900
We’re told that each picture of a pink circle stands for one student.
00:05:02.630 --> 00:05:09.150
We have to answer three different questions about the information in the picture graph.
00:05:10.000 --> 00:05:16.040
The first question is asking us, “What do most students eat for breakfast?
00:05:16.560 --> 00:05:19.730
Fruit, toast, or eggs.”
00:05:21.270 --> 00:05:32.910
To find out which category or which type of breakfast is the most popular, we’re looking for the category with the most pictures of pink circles.
00:05:33.880 --> 00:05:35.540
Which category is it?
00:05:36.560 --> 00:05:37.650
It’s eggs.
00:05:38.740 --> 00:05:47.350
We can see without counting that there are more pictures of pink circles next to eggs than there are next to fruit or toast.
00:05:48.560 --> 00:05:53.440
This means that eggs are the most popular type of breakfast.
00:05:54.380 --> 00:05:57.680
Most students eat eggs for breakfast.
00:05:58.840 --> 00:06:03.700
The next question is asking us how many students eat fruit for breakfast.
00:06:04.720 --> 00:06:10.590
Remember, each picture of a pink circle stands for one student.
00:06:12.130 --> 00:06:20.560
There are two pink circles in the fruit category, which stands for two students.
00:06:21.400 --> 00:06:28.170
The last question asks us how many more students eat toast than fruit.
00:06:29.050 --> 00:06:33.400
We need to compare the fruit and toast categories.
00:06:34.510 --> 00:06:40.640
Two children like fruit and four like toast.
00:06:42.100 --> 00:06:45.480
Four is two more than two.
00:06:47.000 --> 00:06:53.370
There are two more circles in the toast category than there are in the fruit category.
00:06:56.150 --> 00:07:00.500
Two more students eat toast than fruit.
00:07:02.320 --> 00:07:07.730
The table shows the number of points obtained by three students in a test.
00:07:08.850 --> 00:07:12.670
What is the least number of points obtained in the test?
00:07:14.080 --> 00:07:17.050
In this question, we’re shown a picture graph.
00:07:17.780 --> 00:07:23.860
The picture graph shows the number of points three different students got in a test.
00:07:24.740 --> 00:07:30.710
The students are Madison, Chloe, and Liam.
00:07:31.620 --> 00:07:36.990
And we’re told that each star represents one point.
00:07:37.930 --> 00:07:45.760
The question is asking us to work out the least number of points obtained or scored in the test.
00:07:46.710 --> 00:07:49.840
Let’s count the number of points that Madison scored.
00:07:51.340 --> 00:07:54.130
Each star represents one point.
00:07:54.500 --> 00:08:01.270
One, two, three, four, five, six, seven, eight, nine.
00:08:02.580 --> 00:08:05.310
Madison scored nine points.
00:08:05.900 --> 00:08:07.680
How many points did Chloe score?
00:08:09.230 --> 00:08:13.440
One, two, three, four, five.
00:08:14.620 --> 00:08:16.700
And how many points did Liam score?
00:08:17.800 --> 00:08:22.800
One, two, three, four, five, six, seven.
00:08:24.810 --> 00:08:28.460
So, which was the least number of points scored?
00:08:29.130 --> 00:08:32.520
Nine, five, or seven.
00:08:33.740 --> 00:08:38.250
Madison has nine stars, so she scored the most points.
00:08:39.310 --> 00:08:42.170
And Chloe scored the least.
00:08:42.880 --> 00:08:45.870
Five points is less than seven points.
00:08:46.340 --> 00:08:49.130
It’s also less than nine points.
00:08:50.000 --> 00:08:54.230
The least number of points obtained in the test is five.
00:08:55.620 --> 00:08:57.340
What have we learned in this video?
00:08:59.210 --> 00:09:03.250
We’ve learned how to read information in picture graphs.
00:09:03.990 --> 00:09:09.340
We’ve also learned how to find the category with the most or least items.
