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
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.
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.

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.

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.
