A sentence stands alone to express a complete thought. Surprisingly, most 5th graders still need to revisit the concepts of complete sentences and fragments and how to punctuate the four different kinds of sentences. Combining shorter sentences into longer, more complex sentences is another skill that requires practice. Students get all of that needed review in this unit, in addition to learning how to identify and fix run-on sentences.

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.
