What this lesson shows
A jar at home, a savings account, or a bank: compare which keeps money safe and which pays interest, and what banks do with money.
The worked example
The lesson works this one step by step: $100 saved, $2 interest a year. Then your kid tries one like it on paper.
The steps
- Jar: easy to reach, no interest
- Bank: kept safe, pays interest
- Banks lend savings to borrowers
Helping at home
Read each problem aloud. A jar keeps the same amount; a savings account adds its interest. Your kid adds the interest, then subtracts to see how much more the account holds.
If your kid gets stuck
Jar: the same. Account: add the interest.
