This was a super-loved club I ran at my school! The best way I found to run the club was by setting out labeled containers with all the different colors all over the tables before students came in. This made it so no one was waiting to switch out colors, and instead gave them a fun scavenger hunt to find the next color/letter they needed, while also giving them the chance to sit next to and talk with all the club members. For this club we bought small diamond art stickers found on amazon. I also went on to try this project with the kindergarteners at my school, and they loved it too!
