This document outlines a 60-minute English lesson plan aimed at helping students use the third conditional to talk about an imaginary past and write sentences describing the fictional past of the main character in David Copperfield. The lesson includes a warmer discussing the character's problems, a presentation on third conditional grammar forms, a controlled practice activity completing sentences in the grammar forms, a listening activity to identify short grammar forms, and production activities where students write letters to the character and participate in a debate about positive versus negative thinking.
