This skill will surely come up on state writing exams. Combining sentences can be very tricky and shows up in so many different forms. I am creating activities that focus in on each type of combining sentences so that students can focus in on and understand each form in isolation. This is a sorting activity that allows students to apply comma rules to sentences. This set includes sentences with coordinating conjunctions, prepositional phrases, commas in a list, and commas to set off a word or name at the beginning of a sentence.
