Entry Events

Events that will be used to introduce the project to students

The 'One Word' Manifesto

The classroom is transformed into a dark studio with a single, massive, glowing wooden letter '?' in the center. Students must investigate 'The Power of a Single Word' by selecting one evocative word that represents a social issue, calculating the precise surface area and lighting spacing (Math) while writing an accompanying artist statement that analyzes the word's etymology and rhetorical weight (English).

📚

Portfolio Activities

These activities progressively build towards your learning goals, with each submission contributing to the student's final portfolio.

Activity 1

The 'One Word' Manifesto

Before touching a saw or a calculator, students must define the purpose of their marquee letter. In this activity, students select a single, evocative word that represents a social issue or a community value. They will perform a 'rhetorical deep dive' into this word, exploring its etymology, its history, and why a specific font (typography) conveys the right mood for that word.

Steps

Here is some basic scaffolding to help students complete the activity.

1. Select one powerful word that resonates with a community issue (e.g., 'HOPE', 'EQUITY', 'RISE').

2. Research the etymology (origin) of the word and how its meaning has evolved over time.

3. Select three different fonts and analyze how the visual weight of each font changes the 'tone' of the word.

4. Draft a statement explaining how this word will impact a stakeholder and why specific design choices were made.

Final Product

What students will submit as the final product of the activityA written 'Artist Statement' or 'Manifesto' (approx. 500 words) that justifies the word choice and typography.

Alignment

How this activity aligns with the learning objectives & standardsThis activity aligns with CCSS.ELA-LITERACY.W.9-10.2 by requiring students to examine and convey complex ideas and information clearly through the analysis of their chosen word's rhetorical weight.

Activity 2

Scaling the Soul of Design

Students move from concept to geometry. Using a small printed template of their chosen letter, students must determine a scale factor to enlarge it to a marquee size (e.g., 3 feet tall). They will use similarity transformations to ensure the proportions of the font remain perfect during the enlargement process.

Steps

Here is some basic scaffolding to help students complete the activity.

1. Measure the dimensions of the small-scale letter template in centimeters.

2. Calculate the required scale factor to reach the target height for the final wooden structure.

3. Use a grid system or coordinate geometry to plot the points of the letter onto a large piece of butcher paper.

4. Verify similarity by checking that the ratios of corresponding side lengths are equal and all angles remain congruent.

Final Product

What students will submit as the final product of the activityA full-scale paper blueprint of the letter with all scale factor calculations documented.

Alignment

How this activity aligns with the learning objectives & standardsThis activity aligns with CCSS.MATH.CONTENT.HSG.SRT.A.2, as students use scale factors to ensure their large-scale letter is geometrically similar to their small-scale template.

Activity 3

The Geometric Blueprint

With a blueprint in hand, students must now act as engineers. They will deconstruct their letter into composite geometric shapes (rectangles, triangles, circles) to calculate the exact amount of wood needed for the face and the 'troughs' (sides). They will also use perimeter calculations to determine the spacing for the marquee lights.

Steps

Here is some basic scaffolding to help students complete the activity.

1. Identify and draw the geometric sub-shapes that make up your letter (e.g., the letter 'A' might be two trapezoids and a rectangle).

2. Calculate the total surface area of the letter face and the total length of the side walls (troughs).

3. Determine the number of LED bulbs needed based on the perimeter, ensuring even spacing (e.g., one bulb every 4 inches).

4. Calculate the total cost of materials based on current wood and lighting prices.

Final Product

What students will submit as the final product of the activityA 'Technical Spec Sheet' including a material list, budget estimate, and surface area/perimeter calculations.

Alignment

How this activity aligns with the learning objectives & standardsThis activity aligns with CCSS.MATH.CONTENT.HSG.MG.A.1 (modeling objects as geometric shapes) and CCSS.MATH.CONTENT.HSG.GMD.A.3 (using formulas to solve surface area problems).

Activity 4

The Artisan’s Assembly Guide

As students begin the physical construction (or prepare for it), they must document the process. This activity tasks students with writing a professional-grade technical manual that someone else could use to build the same letter. This requires clear sequencing, precise terminology, and the use of diagrams.

Steps

Here is some basic scaffolding to help students complete the activity.

1. Outline the chronological steps of construction, from cutting the wood to wiring the lights.

2. Identify key safety protocols and specific tools required for each step (e.g., miter saw, wood glue, drill bits).

3. Write clear, concise instructions using imperative verbs (e.g., 'Measure,' 'Align,' 'Secure').

4. Incorporate 'Tech Tips' that explain common pitfalls discovered during the prototyping phase.

Final Product

What students will submit as the final product of the activityAn illustrated 'Artisan’s Assembly Guide' (Technical Manual).

Alignment

How this activity aligns with the learning objectives & standardsThis activity aligns with CCSS.ELA-LITERACY.W.9-10.2, focusing on writing technical documentation and using precise language to explain a complex process.

Activity 5

The Luminary Pitch

In the final phase, students act as design consultants pitching their work to a community stakeholder. They must use their math data to prove efficiency and their English analysis to prove the word’s impact. They will present their finished (or near-finished) marquee letter alongside their portfolio of work.

Steps

Here is some basic scaffolding to help students complete the activity.

1. Synthesize the rhetorical analysis (Activity 1) and the technical data (Activity 3) into a cohesive argument.

2. Create a visual presentation that highlights the 'Why' (meaning) and the 'How' (math/construction).

3. Practice a professional delivery that uses evidence to justify why the chosen word and design suit the stakeholder's needs.

4. Prepare to answer technical questions regarding scale factor and material costs during a Q&A session.

Final Product

What students will submit as the final product of the activityA 5-minute 'Design Pitch' delivered to a panel of peers or community members, supported by a visual slide deck.

Alignment

How this activity aligns with the learning objectives & standardsThis activity aligns with CCSS.ELA-LITERACY.SL.9-10.4 (presenting findings and evidence) and CCSS.ELA-LITERACY.W.9-10.1 (forming an argument for design choices).
