Entry Events

Events that will be used to introduce the project to students

The Forensic Accounting Autopsy

Students enter to find a 'Crime Scene' of a failed local business, including unpaid invoices, a confusing menu with low-margin items, and a bank statement in the red. They must act as forensic accountants to identify the exact mathematical errors in overhead and unit pricing that led to the collapse before proposing a 'Phoenix Plan' to revive it.
📚

Portfolio Activities

Portfolio Activities

These activities progressively build towards your learning goals, with each submission contributing to the student's final portfolio.
Activity 1

The Forensic Profit Autopsy

Before building their own business, students must understand why others fail. In this activity, students act as lead auditors to analyze the 'Forensic Accounting Autopsy' evidence. They will translate messy, inconsistent data (e.g., costs in grams vs. sales in ounces) into a standardized spreadsheet to reveal the 'hidden' losses of the failed business.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Review the 'Crime Scene' documents (invoices, menus, bank statements) and list all items with their associated units.
2. Convert all material costs and sales prices into a single, consistent unit of measure (e.g., cost per unit or cost per gram).
3. Calculate the 'True Unit Margin' for each item on the failed business's menu by subtracting the unit cost from the sale price.
4. Identify the 'Red Zone' items—products that were actually losing money despite being sold—and explain the mathematical error (e.g., failure to account for shipping units or labor time).

Final Product

What students will submit as the final product of the activityA 'Correction Memo' that identifies exactly where the failed business miscalculated its margins, supported by a standardized unit-cost spreadsheet.

Alignment

How this activity aligns with the learning objectives & standardsHSN-Q.A.1: Use units as a way to understand problems and to guide the solution of multi-step problems; choose and interpret units consistently in formulas. This activity requires students to standardize inconsistent units from the 'failed' business to find the true financial discrepancies.
Activity 2

The Unit Margin Blueprint

Students transition from auditors to entrepreneurs. They will identify a local community need and design a product or service to solve it. To do this, they must define every 'input' quantity—from the exact amount of raw material to the 'opportunity cost' of their own labor hours.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Identify a local community need and propose a micro-enterprise product or service to solve it.
2. Create a Bill of Materials (BOM) listing every single physical component needed, including its bulk cost and the amount used per unit.
3. Define 'Labor Quantities' by timing how long it takes to produce one unit and assigning a fair market hourly wage to that time.
4. Research and define 'Fixed Quantities' (overhead) such as marketing, equipment depreciation, or space rental.

Final Product

What students will submit as the final product of the activityA 'Variable & Quantity Catalog' that lists every material, labor hour, and overhead expense required for one single unit of their product.

Alignment

How this activity aligns with the learning objectives & standardsHSN-Q.A.2: Define appropriate quantities for the purpose of descriptive modeling. This activity focuses on identifying the specific variables (labor, materials, overhead) that will dictate the success of their own micro-enterprise.
Activity 3

The Break-Even Engine

In this activity, students turn their variables into algebraic power. They will build linear equations that represent their business's total cost and total revenue. By graphing these functions, they will visually locate the 'Break-Even Point'—the exact moment their enterprise stops losing money and starts making it.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Construct a Total Cost Equation: C(x) = (Variable Cost)x + (Fixed Costs).
2. Construct a Revenue Equation: R(x) = (Price)x.
3. Create the Profit Function, P(x) = R(x) - C(x), and simplify the expression.
4. Graph both C(x) and R(x) on a coordinate plane, labeling the axes, scale, and the intersection point (the break-even point).
5. Analyze the graph: Determine how many units must be sold to cover all initial overhead.

Final Product

What students will submit as the final product of the activityA Break-Even Visual Model, including algebraic equations for C(x), R(x), and P(x), and a professional-grade coordinate graph showing the intersection of revenue and cost.

Alignment

How this activity aligns with the learning objectives & standardsHSA-CED.A.2: Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes. This activity moves from static costs to dynamic modeling of revenue, cost, and profit.
Activity 4

The Uncertainty Audit

Entrepreneurship is never certain. Students will identify three potential 'Risk Scenarios' (e.g., a 20% increase in material costs, a slow-sales month, or a broken piece of equipment). They will use probability to calculate the 'Expected Profit' under these different conditions, helping them decide if their business model is truly sustainable.

Steps

Here is some basic scaffolding to help students complete the activity.
1. Brainstorm three realistic risks that could impact your micro-enterprise (e.g., supply chain delay, low demand, or competitor price drops).
2. Assign a probability (p) to each scenario based on local market research or historical data.
3. Recalculate your profit for each scenario (the 'Impact').
4. Calculate the 'Expected Value' of your profit by multiplying each outcome by its probability and summing them.
5. Propose one mathematical strategy to mitigate the highest-impact risk (e.g., changing the unit margin to create a larger 'buffer').

Final Product

What students will submit as the final product of the activityA 'Risk & Mitigation Matrix' that uses probability to forecast profit outcomes under various market conditions.

Alignment

How this activity aligns with the learning objectives & standardsHSS-MD.B.7: Analyze decisions and strategies using probability concepts. This activity challenges students to quantify the 'Risk' element of their business idea using statistical outcomes.
Activity 5

The Phoenix Pitch & Portfolio

The final phase is the 'Venture Pitch.' Students must not only present their math but also prove they have the mindset of an accountable self-starter. They will compile their forensic audit, their unit margins, their break-even graphs, and their risk analysis into a professional proposal for potential 'investors' (classmates and community members).

Steps

Here is some basic scaffolding to help students complete the activity.
1. Synthesize all previous activities into a cohesive slide deck (The Phoenix Plan).
2. Write a 'Founder's Statement' explaining how you took initiative to solve problems encountered during the modeling process (AS-11.1 alignment).
3. Practice 'Mathematical Defensibility': Be prepared to explain any variable or equation in your model during a live Q&A.
4. Deliver the final pitch, highlighting the 'True Cost,' the break-even timeline, and the risk mitigation strategy.

Final Product

What students will submit as the final product of the activityThe 'Phoenix Plan' Pitch Deck and an 'Accountability Log' documenting their independent progress and iterations throughout the 21 days.

Alignment

How this activity aligns with the learning objectives & standardsAS-11.1: I am an accountable self-starter. This final activity focuses on the synthesis of the math into a professional pitch, requiring the student to demonstrate the initiative needed to launch the venture.
