THE MONEY
MYSTERY
Why doesn't your paycheck match the money you earned?
FINANCIAL LITERACY
LESSON 1
The "Wait a Second" Scenario
You worked 10 hours this week at your neighborhood job. Your boss pays you $10 per hour.
Expected: $100.00
Actual Check: $85.00
WHAT HAPPENED?
Where did that $15 go?
The Starting Point
Gross Pay
Definition
The total amount of money you earned before any taxes or deductions are taken out.
The Math
Rate × Hours = Gross
The "Invisible Hands"
Before that money touches your hand, several "invisible hands" reach into the pot to fund shared community services.
Federal Taxes
Goes to the U.S. government for national things like the military, national parks, and roads.
State Taxes
Goes to your state for schools, police, and state highways.
FICA
Goes toward Social Security and Medicare to help seniors and people with disabilities.
The Real Deal
Net Pay
The amount of money you actually take home after all deductions are removed.
Gross Pay − Deductions = Net Pay
Quick Check
Question 1
If you earn $50 washing cars, and your parents take $5 for gas money, what is your Gross Pay?
Question 2
What is your Net Pay in that same scenario?
The Secret Formula
"Gross is BIG, Net is SMALL."
Gross is the total whole pie. Net is the slice you actually get to eat.

!
The "Mystery Slice" Hook (10 mins)
Teacher Script
"Imagine you just finished your first week at a dream job. You know you earned exactly $100. You open your envelope, and there's only $85. You didn't lose it. No one stole it. But it's gone. How would that make you feel?"
Discussion Prompts
What are some reasons that money might be missing? (List student ideas on board)
Is it 'fair' to work for money and then not get all of it?
Activity: The Invisible Hands (15 mins)
Setup
You need: A stack of 100 play-money dollars (or 10 slices of a paper "paycheck pizza").
The Steps:
1
Identify the Gross Pay
Give a student the full $100 stack. Tell them: "This is your Gross Pay—the total whole pie."
2
Assign the "Invisible Hands"
Pick 3 other students to be "Federal Government," "State Government," and "FICA."
3
The Deduction
The "Invisible Hands" take portions from the worker's stack before the worker can "go home" with it. What's left is the Net Pay.
Closing: Reflection (10 mins)
"The invisible hands aren't just taking money to be mean—they are paying for the things we all use together: schools, parks, and helping people who can't work. We will explore those specifics in the coming lessons."
Objectives
Define Gross vs. Net Pay.
Calculate Gross Pay using Rate × Hours.
Recognize common payroll deductions.
Pro-Tip
Use the term "Gross is BIG" and "Net is SMALL" to help students remember. Students often confuse them at first!
Misconception Alert
"Students might think deductions are optional. Clarify that for most jobs, these are mandatory by law."

"Why are YOU paying for your grandmother's doctor visit?"
If you worked today, a tiny bit of your money just helped a senior citizen buy medicine.
How do you feel about that? Is it a good system?

Stands for the Federal Insurance Contributions Act. It's a mandatory payroll tax.
Social Security
Provides income for people when they retire, or if they become disabled and can no longer work.

Community Pot Discussion Cards Community Pot Discussion
Exploring the Purpose of FICA
Group Activity Instructions
Cut out these cards. In your group, take turns drawing a card and discussing the scenario. Think about how FICA taxes (Social Security and Medicare) help the people in each story.
Scenario 1
"The Retired Teacher"
Mrs. Gable taught elementary school for 35 years. Now that she is retired, she doesn't receive a paycheck from the school anymore. She uses her Social Security check to buy groceries and pay her rent.
Discuss:
Without FICA taxes from current workers, how would Mrs. Gable pay for her life?
Scenario 2
"The Unexpected Injury"
Mr. Chen worked as a delivery driver until a serious back injury made it impossible for him to work. Because he paid into Social Security for years, he now receives disability support payments to help take care of his family.
Discuss:
How is this system like an "insurance policy" for every worker?
Scenario 3
"The Hospital Visit"
Grandpa Joe is 75 years old. He needed a surgery that cost thousands of dollars. Because he has Medicare, most of that bill was paid for by the government using funds collected from payroll taxes.
Discuss:
Is it better for everyone to pay a little bit now, or for seniors to pay huge bills alone later?
Scenario 4
"Your Future Self"
Imagine it is the year 2080. You are 70 years old and ready to retire. You hope there is still a "community pot" available to help you enjoy your golden years after a lifetime of hard work.
Discuss:
Why is it important for the system to keep going even when you are young?

You have two job offers. Job A pays $20.00 per hour. Job B pays $21.00 per hour. However, Job B is in a city with much higher taxes. If your Gross Pay is higher at Job B, is it guaranteed that your Net Pay will also be higher? Why or why not?

If you cannot afford it in one week, how many weeks of Net Pay will you need to save to buy it?
Post-Simulation Reflection
1. Look back at your Gross Pay and your Net Pay. Which number surprised you more? Why?
2. Some people prefer jobs with high hourly rates even if they work fewer hours. Others prefer more steady hours even if the pay is lower. Which did you choose, and why?
3. Now that you've seen how much "invisible hands" take from your check, does it change how you think about earning money? Explain.
