Teaching Economy in 4th or 5th grade

I am not a licensed elementary teacher. Subbing this year has shown me so much about the workings of the lower grades. I have tried to piece together how teachers work with state and national standards, and it's a bit confusing. One aspect is teaching financial and economic literacy. In several classes I have been in, part of the reward/consequence system involves "payment" and "fines."

Here are the methods I have seen in action:
Method Ja
background: This is a fifth grade class with GLAD influence.

• students have jobs they get paid for. Some jobs are paid better than others (teaches that resources are allocated differently)
• Students make wallets where they keep their money.
• Students are fined for misbehavior and not turning in homework. They must take home their fine and get it signed and then pay the teacher out of their wallets. 
• Students may buy privileges from the BANKER (one of the classroom jobs) 
• examples include comfy toes, teacher chair, teacher desk, seat bump, computer time, etc.
• loans can be given and interest is collected. 

Method Je

background: This is a fourth grade class with GLAD influence. 

• students start with 5 fuzzies. They can be taken away for misbehavior.
• Fuzzies can be turned in for raffle tickets.
• raffle tickets buy objects students may need (pencils, spiral notebooks, emergency bathroom passes, etc.) or want (sharing time, extra recess, homework pass, lunch with teacher, etc.) (teaches the difference between need and want at a financial level.)
• students are responsible for their own tickets, BUT teacher has set up baggies in each cubby to hold tickets and fuzzies. 

At some point during the school year, students should be prompted to write about their experience with the fuzzies or job scenarios. This would likely be done without the students even knowing it was an assessment for economy standards.
