If you have not done so already, refer students to the Vocabulary bank at the end of Unit 1. Tell students to explain how this lesson can help them deal with new words in context. If you wish, make three groups. Group A looks at the first section, Using related words. Group B looks at the second section, Removing prefixes. Group C looks at the third section, Removing suffixes. Then make new groups of three with a student from each of the previous groups in each to explain to each other.
