The bar graph shows how many
children like each type of food for dinner. Which food is most popular? How many more children like pizza
than curry?
This bar graph shows us children’s
favorite dinners, burger, curry, or pizza. We have to read the information
presented in the graph to work out which food is the most popular. To answer this question, we need to
figure out which of the bars is the longest. It’s the pink bar. This means the food which is most
popular is pizza.
In the second part of the question,
we need to work out how many more children like pizza than curry. We can imagine the scale on the
graph is a number line. And this is where the bar for pizza
reaches on the number line, between the numbers 40 and 50. The difference between 40 and 50 is
10. And there are five small
intervals. That means each of the smaller
intervals is worth two. 40, 42, 44, 46, 48, 50. The number of children who like
pizza is 42.
This arrow shows the number of
children who liked curry the best. The number of children who like
curry best is between the number 20 and 30 on the scale. And we know that each interval is
worth two. So let’s start counting in twos
from number 20. 20, 22, 24, 26. We have to find the difference
between 26 and 42. We can start at number 26 on the
number line and count forward in twos until we reach 42. Two, four, six, eight, 10, 12, 14,
16. 16 more children like pizza than
curry. We read the information in the bar
graph. The most popular food is pizza. We knew this because the pink bar
is longest. 26 children preferred curry, and 42
preferred pizza. 16 more children like pizza than
curry.
