I love to use table helpers. I also like to switch my table groups frequently through the year.
After years of spending lots of time and stickers changing my students around at their tables and not wanting 2 of the same "helper" at the same table I figured out this system.
I contact paper down 1 main table color group with coded color symbols for each helper. These stay on the table year-long. Then I add on whatever name plate I'd like on the table. My kindergarten kiddos never seemed thrown by not having the color specifically on their name plate. Being a helper is so motivating that even those who struggled with colors learned them quickly! The best part is you can switch around names even during class if need be and not throw off your helper system!
