This unit not only builds students' vocabulary, it also enables students to explore how words are related, in meaning, sound and construction. Learners will also discover some of the ways words are constructed using derivational root words, prefixes, suffixes, and compound words. Students will also learn strategies we use to shorten words and phrases like acronyms and abbreviations.

Words work together in a sentence, each one performing a different task. By fifth grade, students have become more adept readers and writers and they are familiar with the basic parts of speech. The activities in this unit revisit some of the basics and also add depth to their existing understanding. Students will engage in such topics as superlative adjectives, correlative conjunctions and prepositional phrases, to name a few.
