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.

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.

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.
