You can use the information from a bar graph to solve a
question.
UNDERSTAND
What
is the question being asked? You
need to find the difference between the number of people who
own retrievers and number of people who own setters.
Plan
How can you solve the question? Find
the two bars you're comparing. Read the number scale for
each bar. Subtract to compare the numbers.
Solve
The bar for
retriever owners shows 30. The bar for setter owners shows
15.
30 - 15 = 15 So, 15
more people own setters.
Example 2
Nicole likes
to skate for exercise. She skated 2 miles the first week. Each
week, she skated 1 more mile than the week before. She did this
for 5 weeks.
What was the total number of miles
Nicole skated?

UNDERSTAND
What
is the question being asked? You
need to find the total number of miles Nicole traveled.
Plan
How can you solve the question? Use
a table to organize the information. Then add the number of miles
she skated each week to find how far she skated in 5 weeks.
Solve
2 + 3 + 4 + 5 + 6
= 20
She skated 20 miles in all.
Remember:
Graphs and
tables are common sources of information in everyday life,
so it is important to read labels and titles
carefully.
