These are charts that can be hung in the classroom for students to use as they self assess during learning. Self awareness of mastery can be done quickly and easily with color codes and numbers. You can use this color and number system for students while they do whole group, small group, or even independent work. Students can put a color dot on work to show if they understood or not. Students can write in the colors on an exit slip to show understanding. Students can write in the colors on open ended questions as well.
