Lesson Narrative
Students learn the mathematical formulation of a true emergency fund. Instead of picking a random savings goal, they will calculate their exact "Baseline Survival Number" by stripping away discretionary spending. They will then multiply it by 3 and 6 months to define a mathematically sound safety net, evaluating how their specific career paths dictate the size of their required fund.
Learning Goals
• Differentiate between standard monthly expenses and "baseline survival" expenses.
• Calculate a 3-month and 6-month baseline emergency fund target.
• Evaluate how different career paths (salary vs. freelance) dictate liquidity requirements.
Student Facing Learning Goals
• Let's calculate exactly how much cash we need to survive if we lose our jobs.
Student Facing Learning Targets
• I can calculate my baseline survival number.
• I can determine my 3-month and 6-month emergency fund targets.
• I can explain where to safely store an emergency fund.
Required Academic Standards
National Jump$tart Standards:
• Saving and Investing (Standard 1): Compare how saving and investing build wealth and help meet financial goals.
Glossary Entries
Emergency Fund: Highly liquid cash reserved strictly for unexpected financial crises or job loss.
Baseline Survival Number: The absolute minimum monthly dollar amount needed to keep you housed, fed, and safe (the "Four Walls").
Four Walls: The core survival categories: Housing, Utilities, Basic Food, and Transportation.
Income Shock: A sudden, unexpected drop or total loss of income.
Lesson
Warm Up
2.9.1: What is an Emergency?
Launch: Have students stand in randomized groups of 3 at vertical whiteboards. Present the prompt verbally or project it. Give them 4 minutes to write their answers.
Synthesis: Select two groups to share. Establish the definition of a financial emergency: It must be Unexpected, Necessary, and Urgent. A planned purchase is a "Sinking Fund," not an emergency.
Student Facing Task
Categorize these three events as either a "True Emergency" or a "Planned Expense/Want":
1. Buying holiday gifts for your family.
2. A blown tire on your car.
3. Upgrading to the new iPhone because your screen has a crack in it.
Activity 1
2.9.2: Finding the Baseline
Launch: Keep students at their whiteboards. Project the budget. Give groups 8 minutes to strip the budget down to the Four Walls.
Synthesis: Have the class observe the boards. (Teacher Key: Rent $1000 + Groceries $300 + Car/Insurance $400 = $1,700 Baseline). Emphasize that when you lose your job, Netflix, restaurants, and new clothes go to $0 immediately. The baseline is strictly survival.
Student Facing Task
Alex just lost his job. Look at his normal monthly budget: Rent ($1000), Groceries ($300), Netflix ($20), Eating Out ($150), Car Payment/Insurance ($400), New Clothes ($100).
1. Strip away all the "Wants." Calculate his absolute "Baseline Survival Number" (the minimum dollar amount he needs just to survive the month). Show your math.
Activity 2
2.9.3: The 3-to-6 Month Target
Launch: Present the task. Give the whiteboard groups 8 minutes to calculate the targets and debate the career question.
Synthesis: Facilitate a class debate. (Key: 3-month = $5,100. 6-month = $10,200). Ask: "Why does the graphic designer need 6 months, while a tenured teacher might only need 3?" Explain that income volatility dictates your risk. Freelancers have massive income shocks; tenured government employees have highly stable incomes.
Student Facing Task
Using Alex's Baseline Survival Number from Activity 1 ($1,700):
1. Calculate his 3-month emergency fund target.
2. Calculate his 6-month emergency fund target.
3. If Alex is a freelance graphic designer whose income changes every month, should he aim for the 3-month target or the 6-month target? Why?
Lesson Synthesis
Lesson Synthesis (5 min)
Narrative: Bring the class back to their seats. Review the student-facing learning targets. Ask the class: "If you have $10,000 saved, does that mean you are wealthy?" (Answer: No, it means you are protected. Wealth building (investing) does not start until the emergency fund is fully funded).
Cool Down
2.9.4: The Mattress vs. The Market
Narrative: This exit ticket serves as a formative assessment linking Lesson 3 (Savings Vehicles) to Lesson 9.
Teacher Rubric: A successful response must state that the stock market is too volatile (you might lose the money right when you need it) and physical cash loses value to inflation. The correct place is a High-Yield Savings Account (HYSA) because it offers growth with high liquidity.
Student Facing Task
Why is it a terrible idea to put your 6-month Emergency Fund into the Stock Market, and why is it a terrible idea to keep it as physical cash in a safe? Where is the mathematically correct place to store it?
