Student Handout — Inflation (Week 14)
This handout summarizes what we learned in Week 14. Share it at home with a caregiver or trusted adult if you want.
What Is Inflation?
Inflation means prices go up over time. The same item costs more this year than it did last year.
A Simple Example
| Year | Price of a Sandwich |
|---|---|
| 2020 | $4.00 |
| 2022 | $4.50 |
| 2024 | $5.00 |
| 2026 | $5.50 |
The sandwich did not change — but the price did. That is inflation.
What Is Buying Power?
Buying power is how much stuff your money can actually buy.
If you have $20 and a sandwich costs $4, you can buy 5 sandwiches. If inflation raises the price to $5, your $20 now buys only 4 sandwiches.
You still have $20 — but your buying power went down.
Why Does Inflation Happen?
Inflation can happen for many reasons. Here are two common ones:
- More money, same stuff. If there is a lot more money floating around but the same amount of things to buy, sellers can charge more.
- Things cost more to make. If ingredients, materials, or energy become more expensive, the final product costs more too.
Guided Extension: Inflation and Saving
This comparison is optional extension work for older or ready learners.
Inflation is why saving money under your mattress is not always the best plan:
| Scenario | Your $100 After 5 Years |
|---|---|
| Under your mattress (0% interest, 3% inflation) | Still $100, but it buys what $86 used to buy |
| In a bank (3% interest, 3% inflation) | About $116, and your buying power stayed about the same |
| In a bank (5% interest, 3% inflation) | About $128, and your buying power actually grew |
The lesson: To protect your buying power, your savings need to earn interest that keeps up with (or beats) inflation.
Inflation Is Not Always Bad
- A little inflation (1–3% per year) is normal in most economies.
- It can be a sign that the economy is active and growing.
- It becomes a problem when prices rise much faster than people's income.
Key Vocabulary

Guided Extension: Inflation Detective
Ask an older person, use a teacher-provided old menu or ad, or compare a public price example: "How much did _________ cost then?"
| Item | Price Back Then | Price Now | How Much Did It Change? |
|---|---|---|---|
| A gallon of milk | $ | $ | $ |
| A movie ticket | $ | $ | $ |
| A candy bar | $ | $ | $ |
| A gallon of gas | $ | $ | $ |

Talk About It at Home or With a Trusted Adult
Only share what feels comfortable. You can use a public example, a classroom example, or a made-up scenario instead.
- Have you noticed any prices changing over time? Which ones?
- Why can it help to keep savings in a place where they can grow?
- What happens if prices keep going up but money stays the same?
