Building a unit? This order moves from the parts of a sentence to fixing errors and combining ideas, then a mixed review.
- 1Subject and predicate. Show that every complete sentence names who or what it is about and tells what they do.
- 2Sentence types. Sort statements, questions, commands, and exclamations, and match the end punctuation.
- 3Subject-verb agreement. Make the verb match the subject in number so sentences sound right.
- 4Sentence fragments. Find groups of words that are missing a part and finish them into complete sentences.
- 5Run-ons and comma splices. Separate or join two complete ideas correctly instead of running them together.
- 6Conjunctions. Use coordinating and subordinating conjunctions to connect ideas the right way.
- 7Compound and complex sentences. Combine clauses into longer, clearer sentences with the right punctuation.
- 8Capitalization and punctuation. Polish each sentence with capital letters, end marks, and commas.
- 9Mixed review. Blend the skills so students edit real sentences from start to finish.
