I stumbled into an organizational idea last year that went beyond my initial use. For extra flash card practice I used set partners for a week. This was getting rather humdrum (and chaotic) because certain students did not enjoy flashcards. As a way to spark their “want to” I wrote the partner groups on the board and attached two upside down stickers to each group. Once a group was finished for the day they could claim their stickers. (Part of the fun was that they didn’t know what sticker they may be getting.) It did help spark interest for a while but the bonus for me was that I could tell at a glance which groups hadn’t practiced. They usually did not forget to get their sticker.
