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.

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.
