The mysterious comma is arguably the trickiest form of punctuation, which is why assigned it it’s own unit in 5th grade. As students become more sophisticated writers they craft more complex sentences. They incorporate independent phrases and clauses, generate compound sentences, and utilize transition words to combine ideas - and the exercises in this unit will teach them how to use commas correctly in each scenario.

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.
