Interpret bar graphs to answer single-step questions about a context.

Reading bar graphs

Bar graphs show information by using bars to represent numbers.
The bar graph below shows the number of kids that chose each activity as their favorite thing to do on a hot day.
The Eat ice cream bar lines up with 120, which means 120 kids chose eating ice cream as their favorite hot day activity.

Comparing with bar graphs

Bar graphs can also be used to make comparisons.
The bar graph below shows the number of kids that chose each activity as their favorite thing to do on a rainy day.
We can see that kids chose watching a movie the most because the Watch a movie bar is the tallest. But we can also compare different choices by looking at more than one bar.
Practice Problem 2A
How many kids chose jumping in puddles as their favorite activity?
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3/5
  • a simplified improper fraction, like 7/4
  • a mixed number, like 1 3/4
  • an exact decimal, like 0.75
  • a multiple of pi, like 12 pi or 2/3 pi

Practice Problem 2B
How many kids chose looking for rainbows as their favorite activity?
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3/5
  • a simplified improper fraction, like 7/4
  • a mixed number, like 1 3/4
  • an exact decimal, like 0.75
  • a multiple of pi, like 12 pi or 2/3 pi

Sometimes we will need to answer questions by comparing two bars.
Practice Problem 2C
How many more kids chose jumping in puddles than chose looking for rainbows?
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3/5
  • a simplified improper fraction, like 7/4
  • a mixed number, like 1 3/4
  • an exact decimal, like 0.75
  • a multiple of pi, like 12 pi or 2/3 pi

Practice Problem 2D
