I use this graphic organizer to help students remember all the characters who have an impact on Melinda in the novel "Speak" by Laurie Halse Anderson.
I tell students that the girl in the center is Melinda, and that they should write her name somewhere on or around the figure. Then I have them write a character trait or two on the body of Melinda. Finally, in each of the bubbles around Melinda, I have students write a character's name and a few things they know about the character. This can be traits, quotes, characterization, etc.
