In my Personal Finance senior-level class, I have created classroom jobs to help myself and reduce time spent on these tasks. It also ties into the curriculum and I use it to explain Careers and filling out job applications, etc.
Classroom Jobs are not a new idea, but have mostly always been geared to the elementary grades. I have "updated" the job titles and descriptions to be more fitting for high school students. They feel important and in turn are "paid" with bonus points; however, you may create your own system.
This file is completely editable and I would encourage you to personalize it to best fit your needs. You may not want to rotate certain jobs or you may wish to rotate them all. I find it works best to keep certain jobs steady with the same person and create a "substitute" position that fills in any job if a person is absent.
