Words are like legos - they can have interchangeable parts. In this unit students will study the construction of words including roots, prefixes and suffixes. Students will also explore how to modify words to make them possessive, a different part of speech and adjust to signify singular and plural. Understanding the basic building blocks of words, will increase students’ vocabulary, improve their spelling and add strategies for decoding unfamiliar words.

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.

Letter writing is a very engaging and authentic way to learn formatting, punctuation and grammar. The activities in this unit should be learned in tandem with actual letter writing to aunts, uncles or other special far-away people. That way, students can learn and practice the letter writing skills and then apply them in their own letters. It would be especially rich to include their thoughts about books they are reading.
