A project meant to take place over several weeks. Students must create their own business, record both expenses and profits. A very valuable learning experience and KIDS LOVE IT! I gave students class time (40min) Mon-Thurs and had the "market place" on Friday. 3-4 weeks is a good duration. I also recommending inviting other classes to the marketplace!
Copyright slips- so other kids can't "copy"
Ethics violations- if kids are copying or insulting other businesses, students can have a "mediation conference" with the teacher and the offending students.
