This PowerPoint lesson guides students through the departure from the battlefield and Macbeth’s letter to his wife. It enables students to contrast, again, the public figure of Macbeth (loyal subject) and his private thoughts. Students are given tasks to consolidate their learning, exploring in more detail the soliloquy of Lady Macbeth (and what the soliloquy achieves as a dramatic technique) and the powerful symbolism conjured through her words about innocence and the figure of the serpent.
