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.

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.

Verbs do a lot of the heavy lifting in good writing. Understanding the different kinds of verbs and how they are used enables students to write more compellingly. Students will explore how tenses work and how they must agree with and sometimes work together with other words in the sentence. Students will also learn about adverbs, the "sister" part of speech that enhance, or modify, verbs.
