# Graphing a Path to the National Sites

Mathematics and Technology

## Lesson Plan

### Overview

The teacher will introduce the concept of graphs to the students and model for them various types of graphs.  Students will then research how many national sites are located in their state and in one of the states represented on the 2010 quarters.  Students will compare their findings and show the results on a graph type of their choice.

### Objectives

Students will demonstrate an understanding of graphs.

### Time

Two 20- to 30-minute sessions

### Materials List

• 1 overhead transparency (or photocopy) of the "How Many Sites Are There?" worksheet
• 1 class map of the United States
• 1 copy of a text that gives information about graphs
• Chart paper
• Markers
• Pencils
• Graphing software
• Computer

### Keywords

• Bar graph
• Line graph
• Pictograph
• National Site

### Summary

• Read the students a chosen text on graphs.  Review the various types of graphs with the students.
• Model creating a class graph on simple topics (such as favorite colors, how the students get to school, how many brothers and sisters they have).  Be sure to show the students how to complete each type of graph by using a pictograph, bar graph, and line graph.
• Describe the America the Beautiful Quarters® Program for background information.  The program is described at .  Tell the students that the back of a coin is called the reverse, and "obverse" is another name for the front.
• With the students, examine each of the five 2010 quarter designs.  Locate each of the sites on a class map.  Note their position in relation to your school's location.  Demonstrate how to find the national sites located in each state, using your own state as an example.  Answer any student questions.
• Allow the students time to research one of the featured states and identify which national sites are located there.  Have the students record their findings for their own state and the chosen state on the "How Many Sites Are There?" worksheet.
• Model for the students how to create a graph using the graphing software and one of the examples from the previous class.
• Have the students complete the graphing project by choosing a graph style and creating a graph from the data on their "How Many Sites Are There?" worksheets with the graphing software.  Help the students present the graphs to the class.

### Assessment

• Take anecdotal notes about the students' participation in class discussions.
• Use the students' worksheets and projects to evaluate whether they've met the lesson objectives.

### Differentiated Learning

• Allow students to work in pairs.
• Allow students to use a scribe to label their worksheets.
• Allow students to use a template to complete the project.

## Standards

### Mathematics

National Council of Teachers of Mathematics (www.nctm.org)

• Data Analysis and Probability:  Students will formulate questions that can be addressed with data and collect, organize, and display relevant data to answer them.

### Technology

International Society for Technology in Education (www.iste.org)

• Research and Informational Fluency: Students apply digital tools to gather, evaluate, and use information.

• Create your own sample graph using the software program to model the project expectations for the students.
• Fill in the name of your state on the "How Many Sites Are There?" worksheet ahead of time.
• Bookmark websites for the students to use in their research.
• Create a template on the software you will be using to help students complete the graph.

## Student Version

### Objectives

You will learn how to complete a bar graph, line graph, or pictograph from the information that you will collect on the national sites.

### Step-By-Step Directions

1. Use the links on www.nps.gov to find out how many national sites are in your state.
2. Record your state name and the number of sites on your "How Many Sites Are There?" worksheet.
3. Now locate one of the featured states for 2010 and find out how many national sites are located there.
4. Record that state name and the number of sites on your "How Many Sites Are There?" worksheet.
5. Choose whether you want to make a bar graph, line graph, or pictograph.
6. Using the graphing software, create your graph using the findings on your "How Many Sites Are There?" worksheet to show how many parks are in the two states that you researched.
7. Present your graph to the class or another class when it is complete.
