This a great tool for both students and teachers.
I have used these learning scales for 2 years and it proved to be very beneficial. Each student has an opportunity to self assess how well he or she understands a lesson.
It is also a great tool for LLI lessons and learning centers.
Simply copy on 11 / 17 paper (or colored) and laminate.
After laminating place posters in an area that's visible from all angels of the room. posters should be one above the other to make it easier for the student. Two sets would be ideal if posters cannot be visible from all angles.
