**Constructing Graphs**Created by Scott Mangum**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.**Why construct graphs?**• Graphs are visual aids that help people understand information.**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?**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**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**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.**After you have gathered your information you can start**making your graph. You must follow the five steps to making a graph.**Step 1 to graphing.**• Draw a subject and scale axis. • Axis are the horizontal and vertical lines that start the graph.**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**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**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**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**Types of Graphs.**Bar Graph**Pictograph**= 1 cone Strawberry Chocolate Vanilla**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.
