1. Circle Graphs, Line Plots, and Pictographs Created by Cher Wheeler Oak Hill Elementary School cwheeler@burke.k12.nc.us

2. Circle Graphs show “parts of a whole.”

3. Interpret this circle graph:

4. All of the information displayed in a circle graph must equal 100% or the entire group.

5. An easy way to make a circle graph is to think of a clock and divide the circle accordingly.

6. ½ of the clock would represent 50% of an entire group

7. An easy way to make a circle graph is to think of a clock and divide the circle accordingly. 1/4 of the clock would represent 25% of an entire group

8. An easy way to make a circle graph is to think of a clock and divide the circle accordingly. 1/3 of the clock would represent 33% of an entire group

9. Line Plots A line plot is a display of data along the number line with points, or symbols, indicating the frequency or tally of information about a single question or category.

10. Interpret this line plot:

11. How many people participated in this survey?

12. Pictographs A pictograph is a representation using pictures or icons to report the frequencies regarding a category or question.

13. What does this pictograph show? How many rainy days were in March?

14. Be sure to look for a key or legend. Sometimes one figure represents more than one item or person.

15. Watch for fractions in the key!

16. Interpret this graph:

17. What do circle or pie graphs show? Parts of a whole!

18. What do line plots show? The frequency of a certain response

19. What do pictographs show? A picture representation of the frequency of a response

20. Now let’s make some graphs!
