Third grade writers will be tasked with writing longer and more complicated sentences. This guided lesson in understanding, constructing and punctuating sentences can support kids as they learn to build bigger and better sentences in their writing. Grammar instruction and practical examples were written by our curriculum experts, complete with a list of recommended building sentence worksheets for third graders.

Sentences are the building blocks of paragraphs. A sentence is a complete thought that can stand alone and in this unit students will learn what comprises a complete sentence and how to identify a fragment, or incomplete sentence. They will explore different kinds of sentences and how to punctuate them. And, to sharpen their craft, students will learn how to spice up their own writing by adding sentence pattern variety.

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.
