This strategy is called behavior bingo. Depending on your class size and age level you can use the 8x8 size or the 10x10 size. Behavior bingo is used as a whole class behavior management tool.
Use this for your special student in your class. Example: I use mine as a reward for good behavior the day before. My VIP gets to use a special pencil box that is full of special pencils, pens, and even glitter glue for them to use. Use this badge on a lanyard for them to wear or tape it to their special pencil box! Enjoy!
