Solve Problems Using Information in a Bar Graph

Information is presented to us in many different formats.

In this activity, we are going to use information in a bar graph to solve some comparison problems.

What this bar graph is showing us:

The bar graph is showing some data about what children had for lunch.

The orange bar represents school lunch and the green bar represents packed lunch.

We can see the days of the week across the bottom.

The numbers up the side tell us the number of children.

Now, let's solve a problem related to this bar graph.

Example

How many more children had a school lunch rather than a packed lunch on Monday?

Answer

We can see that 100 children had a school lunch on Monday while 20 children had a packed lunch.

We need to subtract 20 from 100 to find out how many more had a school lunch.

100 - 20 = 80

80 more children had a school lunch on Monday.

Now it your turn to solve some problems  - good luck!
