Similar to a whole class behavior management strategy, I made this as a student self-assessment technique.
Each desk gets a traffic light and a car. Students move the car on the traffic light during independent work.
Green means "I'm good and don't need any help."
Yellow means "I think I'm okay, but I might need you to check on me."
Red means "I've tried, but I need help!"
I laminated mine for my students so they last longer and I attached the cars with velcro!
