You
can use the information from a bar graph to solve a problem.

UNDERSTAND
What
do you need to find? 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 problem? 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?

You
can use the information from a table to solve a problem.

UNDERSTAND
What
do you need to find? You
need to find the total number of miles Nicole traveled.

Plan
How
can you solve the problem? 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.
