(Edit) - This is what my finished set-up looks like - LOVE it! The rocks are in bucket to the left. When a student nominates another student for a "character rock", they fill out the card (in the basket in the middle), glue the rock with a fitting character trait to the basket (they can use the glue gun by themselves, or ask me for help) and drop the finished rock and card into the bucket to the right (bucket-filling). :) At the end of the week I go through the bucket and hand out the rocks. And that way I have time throughout the week to monitor who is getting nominated for stones, and if there is a student who hasn't received one in a bit, I can drop one in the bucket).
If you're interested in trying this system yourself, I have a post HERE with a link to everything I have included on the bulletin board.
