My students always struggle with theme. I made this graphic organizer so that they can track different motifs as we read The Tragedy of Macbeth. After we finish, I ask them to review the motifs and textual evidence and write a theme for the play. I find that having them track while reading forces them to notice different important aspects of the play.
One teaching tip: students often confuse motif and theme and use them interchangeably. Make sure to define the two before you begin. Then, when they use the motifs at the end of the play to come up with a theme, it will be more clear.
