Picture Graphs
In this video, we will learn how to
read picture graphs to find how many items are in a category or group. And we will learn how to find out
which category or group has the most or least items.
This is a picture graph, at
sometimes called a pictogram. A picture graph or a pictogram
shows us information using pictures. In this picture graph, the pictures
we’re shown are stick people. Each stick person represents one
person. We count one for each stick
person. The picture graph is showing us the
games that children like to play in the playground. Some children like to play with the
skipping rope, and other children like to play with the ball. We call these the categories in the
picture graph. Rope is a category and ball is a
category.
How many children are playing with
the skipping rope? If each stick person represents one
person, we just need to count the number of stick people. In other words, we need to count
the number of pictures in this category. One, two, three, four. There are four pictures in the rope
category. Four children are playing with the
skipping rope. How many children are playing with
the ball? Can you count the pictures? There are two. We know that four is more than
two. So, we can say that playing with
the skipping rope is more popular than playing with the ball. More children like playing skipping
rope than playing ball.
So, we’ve learned that a picture
graph or a pictogram uses pictures to show information. Let’s try some questions now to
help us practice reading information in picture graphs or pictograms.
Benjamin made a picture graph to
show how many children came to the after-school club. The number of boys is more than,
less than, or the same as the number of girls.
We have to complete this
sentence. 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. The picture graph shows us how many
children are in the after-school club. It has two categories, boys and
girls. And we’re told that each picture of
a smiley face stands for one child. How many smiley-face pictures are
there in the boys’ category? One, two, three, four. 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. The number of boys is the same as
the number of girls, four boys and four girls.
We read the information in the
picture graph. We compared the number of boys and
the number of girls. And we found that the number of
boys is the same as the number of girls.
Mason asked his class to choose
what they usually ate for breakfast. What do most students eat for
breakfast? Fruit, toast, or eggs. How many students eat fruit? How many more students eat toast
than fruit?
We know that Mason has asked his
class what they eat for breakfast: fruit, eggs, or toast. We’re told that each picture of a
pink circle stands for one student. We have to answer three different
questions about the information in the picture graph. The first question is asking us,
“What do most students eat for breakfast? Fruit, toast, or eggs.”
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. Which category is it? It’s eggs. We can see without counting that
there are more pictures of pink circles next to eggs than there are next to fruit or
toast. This means that eggs are the most
popular type of breakfast. Most students eat eggs for
breakfast.
The next question is asking us how
many students eat fruit for breakfast. Remember, each picture of a pink
circle stands for one student. There are two pink circles in the
fruit category, which stands for two students.
The last question asks us how many
more students eat toast than fruit. We need to compare the fruit and
toast categories. Two children like fruit and four
like toast. Four is two more than two. There are two more circles in the
toast category than there are in the fruit category. Two more students eat toast than
fruit.
The table shows the number of
points obtained by three students in a test. What is the least number of points
obtained in the test?
In this question, we’re shown a
picture graph. The picture graph shows the number
of points three different students got in a test. The students are Madison, Chloe,
and Liam. And we’re told that each star
represents one point. The question is asking us to work
out the least number of points obtained or scored in the test. Let’s count the number of points
that Madison scored. Each star represents one point. One, two, three, four, five, six,
seven, eight, nine. Madison scored nine points.
How many points did Chloe
score? One, two, three, four, five. And how many points did Liam
score? One, two, three, four, five, six,
seven. So, which was the least number of
points scored? Nine, five, or seven. Madison has nine stars, so she
scored the most points. And Chloe scored the least. Five points is less than seven
points. It’s also less than nine
points. The least number of points obtained
in the test is five.
What have we learned in this
video? We’ve learned how to read
information in picture graphs. We’ve also learned how to find the
category with the most or least items.
