  1. Constructing Graphs Created by Scott Mangum

  2. Mississippi 5th Grade Math Framework • 3b - Draw and label bar, line, circle graphs, and pictographs. • 3c - Gather, organize, and analyze data to create tables, charts, and graphs. • 3d - Incorporate appropriate technology and manipulatives to explore data collection, organization, and interpretation.

  3. Why construct graphs? • Graphs are visual aids that help people understand information.

  4. Let’s make a graph. • Take a survey of the information you need. • A survey is a tool you use to organize information. • You need questions that gather information. • Example - How many students in 1st and 2nd period like chocolate, vanilla or strawberry ice cream?

  5. LINE PLOTS Vanilla Chocolate Strawberry 1ST PERIOD FREQUENCY TABLES 1ST PERIOD Surveys, Line Plots, and Frequency Tables X X X X X X X X X X X X X X X X X X X X X X X X X X X X X X

  6. LINE PLOTS Vanilla Chocolate Strawberry 2ND PERIOD FREQUENCY TABLES 2ND PERIOD Surveys, Line Plots, and Frequency Tables X X X X X X X X X X X X X X X X X X X X X X X X X

  7. Surveys, Line Plots, and Frequency Tables SURVEYS We have 30 students in 1st period class. • 15 students like chocolate ice cream. • 10 students like vanilla ice cream. • 5 students like strawberry ice cream. We have 25 students in 2nd period class. • 10 students like chocolate ice cream. • 11 students like vanilla ice cream. • 4 students like strawberry ice cream.

  8. After you have gathered your information you can start making your graph. You must follow the five steps to making a graph.

  9. Step 1 to graphing. • Draw a subject and scale axis. • Axis are the horizontal and vertical lines that start the graph.

  10. Step 2 to graphing. • Label the subject axis. • The subject axis is the axis that contains the subject of the survey. Types of Ice Cream

  11. Step 3 to graphing. 15 10 5 0 • Choose a scale and label the axis. • The scale axis is the axis with the number scale on it. • The scale should have reasonable numbers. Example 2, 5, 10. Depending on how big the numbers are on the scale. Number of students Types of Ice Cream

  12. Step 4 to graphing. • Label, draw and shade the bars. • Abbreviations are letters used to shorten a word. Number of students Types of Ice Cream

  13. Step 5 to graphing. Ice Cream Preferences • Make a key. • Title your graph. • Make sure the colors in the key match the colors in the graph. Number of students Types of Ice Cream

  14. Types of Graphs. Bar Graph

  15. Double Bar Graph

  16. Line Graph

  17. Double Line Graph

  18. Circle Graph (Pie Chart)

  19. Pictograph = 1 cone Strawberry Chocolate Vanilla

  20. Practice • Survey the different colors of shirts in the classroom. • Put the information in a line plot and then a frequency table. • Build a graph with the information.
