I created a 3-Point Scale (based on 5-Point Scales, but more manageable) for one of my students with autism and am amazed at the changes in his behavior. Not only will he point to indicate how he is feeling and what he needs, he has also spontaneously started verbalizing "I'm angry" or "I need a squeeze", which are statements from the 3-Point Scale.
Knowing that not all students are the same, I created this editable document. I suggest leaving the colors and pictures alone (unless the clip art images will increase the problem behaviors) and simply change the "I'm Feeling" and "I Need" columns to fit your students. This document can be used for any student in any grade!
