## 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?

### 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.

### Step 3 to graphing.

• 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.

### Step 4 to graphing.

• Label, draw and shade the bars.

• Abbreviations are letters used to shorten a word.

### Step 5 to graphing.

Ice Cream Preferences

• Make a key.

• Make sure the colors in the key match the colors in the graph.

### 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.
