I created a list of jobs (there are 22) with descriptions so that every student in the class has a responsibility. I use a job application that I downloaded off TPT which they have to fill out at the start of each new quarter. Whoever uses the best skills and proper evidence and elaboration gets their first choice job. It's a good writing practice motivator. You don't have to use all jobs, I made extra because I know some classes have more students and not everything listed is applicable to each classroom. This list is editable so you can modify if needed. I provided the second page so that you can see some of the jobs.
