Intended to help students improve their vocabulary and spelling skills, this booklet offers activities on synonyms, antonyms, homonyms (including homophones and homographs), and acronyms. It is suggested that the teacher present these types of words as members of the "Nym Family." Ideas for posters and books to be used as instructional aids are given. The activities include writing or rewriting sentences, identifying "nyms" in a sentence, writing short stories, and identifying the full meaning of acronyms. Following the activities, an answer key is provided for the acronym worksheets along with additional ideas for teaching about antonyms, homonyms, and synonyms. This document is part of a collection of materials from the Iowa Area Education Agency 7 Teacher Center project. (DC)
