This guided practice lesson focuses on modeling character evidence in literature. Students will engage in identifying character traits and motivations, citing textual evidence to support their claims, and explaining how a character's decisions impact plot development and consequences. The lesson includes reading a story about a character named Leo, who is determined to solve a mystery late into the night. Various activities such as character trait identification, evidence collection using a Claim-Evidence-Reasoning (CER) frame, mapping character decisions and consequences, and a reflection on the character's traits will enable students to deepen their understanding of the text. An extension challenge encourages students to consider how changing a character's personality trait might alter the story's outcome, fostering critical thinking and creativity.
