This resource focuses on enhancing vocabulary skills by teaching students how signal words, particularly 'but', can indicate contrasts or opposites (antonyms) in sentences. Through a structured approach, students learn to analyze sentences to deduce the meanings of unfamiliar words based on contextual clues. The exercise begins with an example sentence that illustrates this concept, prompting students to identify the contrasting meanings of the highlighted words. They are encouraged to explain their reasoning and reflect on how they might determine word meanings even in the absence of such signal words. This activity aims to foster critical thinking and improve vocabulary comprehension.
