Mathematics Senior Level Capstone Course Unit Overview

Title of Unit: Make Your Vote Count Unit Designers:

Kristin Vaughn, Page County Lisa Rosazza, Page County Tiffany Comer, Page County Pam Walker, Page County Laura Hansen, Culpeper County Editor: Diane Leighty, UVA-SCPS Office of Mathematics Outreach

Context: Our current electoral system awards all electoral votes to the plurality winner of that state. Students will investigate different methods of awarding electoral votes and test their new method on past elections. Students will recommend an alternative way to award electoral votes for selecting presidents. If students believe the current method of selecting the president is satisfactory then they must defend the current method and show how an alternative method would not be better. Number of Class

Unit Title: Making Your Vote Count

Driving Question: How should the United States Constitution award electoral votes in presidential elections?

Problem: The constitution and its amendments have provided a subjective method for awarding electoral votes to states. Our current electoral system awards all state electoral votes to the plurality winner of that state no matter how close the state’s popular vote. Is this a fair method? Does your vote count? Is there a better method of determining who wins the election?

ENGAGE Introduce the problem

Number of hours _1.5__

The teacher will invite a local senator or government teacher to share how the electoral college system works. Or

The teacher will show a video explaining how the electoral system currently works. Several videos that explain the process are in the bulleted list below.

- http://www.commoncraft.com/video/electing-us-president

This video gives a School House rock version of the Electoral College. It is upbeat, catchy and may get your students interested in the project.

ee1f3005a68bfe608934/Electoral-College This video describes one proposed change to the electoral system. It also informs students on the nation’s voting process and why a change is desired.

Teacher Notes:

Teachers can review one possible solution to the problem of awarding electoral votes to different states at

http://www.ksl.com/?nid=960&sid=18116942

Teachers can review information about the Electoral College at http://www.archives.gov/federal-register/electoral-college/faq. html#number. Teachers may then want to recommend this to students.

Students identify 3 voting adults to interview. They explain briefly to the adults how our presidents are selected. Then they should ask if they believe the method is fair and if not how they would like to see our present presidential election process changed. They then respond to the journal prompt.

Teacher note: The journal prompt is intended to get the

students to begin thinking about other ways the election results could be determined.

EXPLORE Whole Class

Number of hours__1_

A whole class brainstorming session about the current

Electoral College model for elections and how a person’s vote counts. To prepare students to work in small groups teacher poses questions and records information generated by the students.

 What do we know about the current Electoral College process?

 What is fair?

 What else do we need to know?

 What are some first steps to get started?

 What resources are available to get you started?

Notes for teacher: Pose probing questions that will bring out the following.

1. Our presidential selection process may not select the president that the majority of the people want.

2. We know that if a candidate wins a state he/she receives all of the electoral votes.

3. We know that electoral votes were instituted during a time when the public was not well informed about the candidate. 4. As students consider fairness do they bring out fairness to an individual, to the population of a state, or other factors to consider.

5. Some ways that the selection process for president could be changed and how.

6. Teachers may want to provide the link to CNN One Page Student News: Electoral College to students

http://www.cnn.com/2008/LIVING/studentnews/07/22/one.sheet.ele ctoral.college/index.html

The journal prompts are to help students reflect on what they have heard or read and begin to identify what they see as a question to guide their research and their proposal.

EXPLAIN Expectations for students work and working together

Number of Hours__1_

Provide students with HO# 1a and 1b, Make Your Vote Count. Review the situation and the expectations for the group’s work.

Inform students they need to consider the following:  What questions does the issue raise?

1. Is our current process fair? Why or why not? 2. Is there a better way to choose a president? 3. What other ways have people suggested or

used in the past?

4. Is it possible to devise a process that is always fair?

5. How would different processes affect past election outcomes?

6. What mathematical models can be used to describe the processes and what mathematics can be used to compare different processes? 7. Groups may develop other questions.

Teacher will review the rubrics and expectations with the students so that students know what is expected of them and areaware of deadlines.

Rubrics for grading are provided including: HO#2 Peer/Self-Evaluation form HO#3 Written Presentation Rubric

The Problem:

The constitution and it’s amendments have provided a subjective method for awarding electoral votes to states. Our current electoral system awards all state electoral votes to the plurality winner of that state no matter how close the state’s popular vote. Is this a fair method? Does your vote count? Is there a better method of determining who wins the election?

Working with your group you will use different methods of mathematical processes to investigate the current mathematical model for awarding the state electoral votes. Then your group will create a mathematical model for at least one alternative method that is better than the current electoral system. Carefully describe your model and test the model with the data from the 1992 election provided with this handout and two other elections. Finally, justify why the new model is better than the current model or why the current model is better.

You will have three weeks to work with your group to develop your proposal with supporting evidence and to present your findings.

Expectations:

 Your group needs to develop a question to guide your research and your proposal. Once your group has determined what needs to be done develop an action plan with goals and tasks for how to work on the problem and how to develop the final products. Develop a table to show this plan which will include what needs to be done, who is the responsible person/persons, and the due dates.

 The group will meet three times with the teacher:

o 1st Meeting: Bring the groups action plan and notes to the meeting. Be ready to discuss 2 possible alternatives the group has explored.

o 2nd Meeting: Bring a rough draft of proposed change you group has identified and supporting mathematical models.

o 3rd Meeting: Final written proposal with supporting documentation and be prepared to trial run of the oral presentation.

 Evaluation

o Peer/Self Evaluation about how the group and individuals carried out their responsibilities. (HO #2)

o Written proposal with supporting documentation. (HO # 3 Rubric)
