This product creates a visual, easy to check assessment system within your classroom. It has a red light green light theme and incorporates anchor words for the students to utilize to indicate their level of comprehension of the lesson. Simple and easy to use, appeals to all age groups and age levels. Simply print them out, laminate them, and put them on the student's desks. It is a great visual way to do self assessment. I would recommend this product for Elementary, Middle and High School age students.
