I have been a girl scout leader for quite some time now and made a very HANDY caper chart when my oldest daughter was a brownie. I wish I had a picture, but I don't. Sorry... I will do my best to describe it to you.
We took a piece of metal (2'x1') and covered it with felt (green for scouts), typed their names on a slip of paper, laminated them and attached a piece of velcro to the backs. THis made it easy to "stick" their names on the jobs for the week.
THen we took the "chart" typed the "jobs" on a slip of paper, laminated them, and attached them with hot glue to the left side of the felt covered chart. Every week we would change the girls jobs by taking their names off the duty they had that week and move their name tags. I also gave the girls a form that I designed for them that showed their job for that week and had them write thier duty on it. (I tried to encourage the girls to give the form to moms/dads when they came to get the girls).
I hope this is helpful. SOrry I don't have a photo.
Blessings,
P.
