This is something that I've used in my 4th grade class to help show my students how to think about their characters. I like to have the students analyze the character's actions, feelings, thoughts, and words, then pick an adjective that describes them. You can see this in the graphic organizer.
There is room for the students to write a sentence about their character. If you desire your students to write more about the characters, there are other sentence starters provided at the bottom.
There is also a self-assessment included on the bottom so you know how confident you students feel.
