I use this in my classroom EVERY day! My students know that if they get a compliment as a class while transitioning through the school, I will add another link to our chain by loping the strip of paper through the last, and stapling it.
I hang ours by our front door as a reminder when we are leaving. When the chain gets to the floor, we vote on a treat to share as a class. That may be extra recess, popcorn party, cupcakes, etc.
Then, we start all over! This has really helped ensure my classes behavior while in line!
I have included a few different options for the compliment chain poem. You can print on colored paper and laminate for durability!
I have also included a few different options for the links themselves!
