Some students ate bananas,
strawberries, or kiwis at a picnic. The given bar graph shows how many
students ate each type of fruit. How many more students ate
strawberries than bananas?
In this question, we’re given a bar
graph to read, and it’s all about a school picnic. We’re told that the students at the
picnic ate bananas, strawberries, or kiwis. We’re also told why this bar graph
is there for. It shows us how many students ate
each type of fruit. And there are two types of fruit
that we need to think about particularly here because we’re asked how many more
students ate strawberries than bananas.
This is a comparing question. We need to compare the bars that
show the number of students that ate strawberries with bananas. And if we look at the labels at the
bottom of our graph, we can see that these are the first two bars. And if we look at the side of our
graph, we can see a scale that goes up in ones, and it’s labeled “Number of
Students.” This is where we’re going to find
the information from that we need. So, let’s see how many students ate
each type of fruit.
First, the bananas. So, we’ll go all the way to the top
of the bar that represents bananas. And we’ll either use a ruler or
we’ll trace across with our finger until we hit the scale. It’s the same height as the number
six. So, we can say six students ate
bananas. And we could label this bar with a
six just to remind us. And if we do exactly the same with
the bar that represents strawberries, we can see that 10 students ate strawberries
on the picnic. You see, it’s level with the number
10. So to find out how many more
students ate strawberries and bananas, we can just work out a subtraction. 10 take away six equals four. And so, we can say that the
difference between 10 and six is four. Four more students ate strawberries
than bananas.
You know, there’s another way we
could have solved this problem. Because we know that each line on
the graph is worth one, we could have counted how many jumps it takes to get us from
the top of the bar that represents bananas to the one that represents
strawberries. The difference is one, two, three,
four. So that’s interesting, isn’t
it? It’s a way to find the answer
without actually reading across to the scale on the side. Well, we’ve used two different
methods, and we found the same answer both times. At the picnic, four more students
ate strawberries than bananas.
