Data-Driven Advocacy
7th Grade Math | 10 Hours
Unit Summary: Students use proportional and statistical reasoning to discover transportation improvements that are most needed in their school’s neighborhood. They will use data created throughout the unit to create a flyer or social media post that advocates for a transportation improvement in their school’s neighborhood.
The project covers all of the “Unit 6: Understanding Proportional Relationships” standards in the MNPS 7th Grade Math Scope & Sequence that are the major work of the grade. It also covers part of the “Unit 8: Statistics” standards. The unit may be taught alongside Unit 6 to provide a real world context to learning or may be completed at the end of the year on its own.

Universal Concept/Big Idea
Connectivity
Enduring Understanding
Well-planned physical connections allow us to access ideas, people, places, and resources.
Driving Question
How can we use data to advocate for more transportation options in our school’s neighborhood?
Materials
For “Day 1: Transportation Challenge,” students will need access to a computer to map routes to common destinations on Google Maps.
For “Day 4: Neighborhood Mapping,” each group will need a large laminated neighborhood map, two computers, string, scissors, and markers or colored pencils for the activity. Contact the Civic Design Center for help printing the map.
Unit Preparation
For “Days 8-9: Flyer Creation,” groups will need plain 8.5x11 paper and markers or colored pencils (or computers if you prefer them to design their flyers on Canva.com).
For “Day 10: Advocacy Plan,” students will need access to computers to research information about a local Council Member and to draft an email using the template in Part 7: Advocacy.
Unit Overview
-
-
Students will explore the pros and cons of different types of transportation that Nashville has to offer.
-
Students will use proportional reasoning in the form of tables, graphs, equations, and verbal descriptions to take a deeper dive into the pros and cons of the different modes of transit.
-
Students will share their analysis with the rest of the class and record their peers’ findings. They will reflect on their findings and prioritize information they believe could be used to persuade people.
-
Students will create a map of the area around their school that includes the existing transportation conditions. They will use a radius to create walk and bike radii and use unit conversions to calculate how many miles of improvements are needed.
-
Students will dive into the survey data from their sample population and represent it with tables, graphs, and percentages. They will reflect on all three representations and how they can be used to persuade people.
-
Students will use a constant of proportionality and percent increase to calculate how many students at their school could walk, bike, or take the city bus to school if there were not transportation infrastructure barriers.
-
Students will reflect on the data they have created throughout the unit and prioritize what they want to include on their flyer.
-
Students will design and create their flyers.
-
Students will create a plan to share their flyer with their Council Member and the surrounding neighborhood.

7.RP.A.2 Recognize and represent proportional relationships between quantities.
a. Decide whether two quantities are in a proportional relationship, e.g., by testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin.
b. Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships.
c. Represent proportional relationships by equations. For example, if total cost t is proportional to the number n of items purchased at a constant price p, the relationship between the total cost and the number of items can be expressed as t=pn.
d. Explain what a point (x,y) on the graph of a proportional relationship means in terms of the situation, with special attention to the points (0,0) and (l,r) where r is the unit rate.
7.RP.A.3 Use proportional relationships to solve multistep ratio and percent problems. Examples: simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error.
7.G.A.1 Solve problems involving scale drawings of geometric figures, including computing actual lengths and areas from a scale drawing and reproducing a scale drawing at a different scale.
7.SP.A.1 Understand that statistics can be used to gain information about a population by examining a sample of the population; generalizations about a population from a sample are valid only if the sample is representative of that population. Understand that
random sampling tends to produce representative samples and support valid inferences.
7.SP.A.2 Use data from a random sample to draw inferences about a population with an unknown characteristic of interest. Generate multiple samples (or simulate samples) of the same size to gauge the variation in estimates or predictions. For example, estimate the mean word length in a book by randomly sampling words from the book; predict the winner of a school election based on randomly sampled survey data. Gauge how far off the estimate or prediction might be.
Interdisciplinary Connections
-
Students will design a flyer with the data they have created to persuade city leaders and the community.
7.VA.Cr1.B Develop criteria to guide art-making or design to meet an identified goal.
7.VA.Cr2.C Apply visual organizational strategies to design and produce a work of art, design, or media that clearly communicates information or ideas
7.VA.R1.A Analyze multiple ways that images influence specific audiences
-
Students will use data to create persuasive arguments for transportation improvements. Students will use mapping to analyze current transportation conditions in their school’s neighborhood.
SSP.04 Construct and communicate arguments by citing supporting evidence to:
• Demonstrate and defend an understanding of ideas
• Compare and contrast viewpoints
• Illustrate cause and effect
• Predict likely outcomes
• Devise new outcomes or solutions
SSP.06 Develop a geographic awareness by:
• Using the geographic perspective to determine relationships, patterns, and diffusion across space at multiple scales
• Analyzing locations, conditions, and connections of places and use maps to investigate spatial relationships
• Analyzing interaction between humans and the physical environment
-
Students will read and analyze infographics that incorporate data. Students will write an email to their Council Member advocating for their proposed transportation improvement.
7.L.VAU.6 Acquire and accurately use grade-appropriate general academic and domain specific words and phrases; develop vocabulary knowledge when considering a word or phrase important to comprehension or expression.
7.SL.CC.2 Analyze the main ideas and supporting details presented in diverse media formats; explain how this clarifies a topic, text, or issue under study.
7.SL.PKI.5 Include multimedia components and visual displays in presentations to clarify claims and findings and to emphasize major points.

-
This project is based on the real world issue of transportation in Nashville. Students will use proportional and statistical reasoning to dive into the pros and cons of transportation, public opinion, and the current conditions in their neighborhood. At the end of the unit, they will take action to advocate for their recommendation to city leaders and community members.
