Students can self-assess their learning and communicate to the teacher in a non-verbal way using these cards on ring. The first card says "I understand pretty well." and is printed on green paper. The second card says "I need some help/practice." and is printed on yellow paper. The third cards says "I don't understand." and is printed on red paper. Print, punch a hole in each card, and attach using a binder ring. Students indicate their understanding during whole group and small group lessons by turning the cars. It is a great tool for teachers to do a quick assessment of their students!
