Words Matter features a conceptual approach to teaching mid- to high-level vocabulary. Each chapter introduces ten words linked together by theme, such as humor, light, heat, and friendship. This common thread helps students to compare and contrast words related in meaning or structure. As a result, students have multiple opportunities to form connections and anchor each new word and its meaning in their long-term memory. Readings also focus on topics of social and historical importance so that students expand their cultural literacy along with their vocabulary.
