The Teacher Guides in this series include all the answers to the student books, along with lesson plans that help assess knowledge, provide oral activities and additional written activities, and present additional strategies to help teachers construct a sensible and effective way to teach vocabulary from a roots-based perspective, even if they have no background in classical languages. (The student book, to which this is a companion, includes 16 lessons teaching many English words with roots, prefixes, and suffixes originating from 40 different Greek and Latin words. Each lesson presents 8-10 words derived from classical roots, with the root forms defined in bold type at the beginning of the lesson. The roots are grouped thematically, and each resulting English word is shown in dictionary format with a pronunciation key, definition, and sentence showing correct word usage in context. Each lesson then provides a variety of exercises combining matching, fill in the blank, multiple choice, antonyms and synonyms, using vocabulary in context, and sentence completion activities.)
