- add, subtract and multiply money.
- set up and balance a bank book.
- calculate interest using decimals.
- set up and use a spread sheet.
Teacher planning
Time required for lesson
1 hour
Materials/resources
- Classroom money: $5, $10, $20, $50, $100
- Chart paper
- Construction paper
- Calculator-optional
- Computer-optional
Pre-activities
Students using calculators need to know how to add, subtract, multiply, divide and find percents.
Activities
- The class determines a salary scale as a reward system. Here is an example of what my class listed. Students earn:
- $100.00
- compliment from another teacher
- perfect math paper
- 100% on a computer test
- 100% on any classroom test
- $50.00
- attendance each day
- homework done
- special turn-ins
- $10.00
- job well done
- lunchroom conduct
- clean desk
Students pay:
- $10.00
- tardy
- talking
- idle
- late work
- disorderly
- $50.00
- verbal fighting
- $100.00
- physical fighting
- The class assigns a banker and bank tellers to distribute and collect money. At the end of a week the students deposit the money earned into a bank book. Here they practice math objectives. They count each bill and multiply that number times its value. They add using decimals. They also must write out the amount earned each week using number words. The bank book can be set up to accommodate any grade level. Example:
- We stopped earning money the week of April 15 and get ready to pay our taxes. The money that is left after taxes is used to purchase items brought in by the teacher. The students write out the amount of their purchase on a teacher prepared check. Here is the tax form I use. It can be adjusted to meet your objectives.
DATE - CURRENCY - HOW MANY - AMOUNT
3-13 - one hundred - 6 - $600.00
- fifty - 3 - $150.00
- ten - 7 - $ 70.00
+_________
$820.00
Total earned is eight hundred twenty dollars.

This lesson also gives each student an understanding that the way to purchase items is to work. They also see that they must work to provide a place to call their own, and that they pay for the school, the library and the services they often take for granted.
Assessment
I use their bank book to assess their computation skills. The tax form assesses direction following and computation skills.
Supplemental information
Comments
The students keep their currency in an envelope. We count the money at the end of each week, and record the amount in the bank book.
I like to reward good behavior and exemplary work in my classroom. I find this activity has positive results in classroom management, math skills, as well as an appreciation for tax money that is spent on school libraries, lunchroom and community services, even the text books the students use.
