Each lesson in these books introduces about twelve new words and contains several exercises plus a Wordly Wise section, which discusss words with interesting histories and distinguishes between words that are commonly confused. Exercises A, B, and C use these new words in context, teach multiple meanings of words, and give practice using the words in sentences. Exercise D is a review of earlier lessons. Correct completion of Exercise E gives part of a quotation, poem, or riddle. A glossary is provided in Books 1-3.
