The last step in the writing process is proofreading. After you have finished developing and supporting your ideas and after you have checked the organization, it is time to put the finishing touches on your paragraph. As your last step you need to check the spelling, punctuation, mechanics, and word choice of your paragraph as well as check to be certain you have a concluding statement. You cannot check all of these things in one reading so you should break the task into sections. First, check the punctuation and mechanics of your paragraphs. This means you are making sure you don't have errors like comma splices or fragments. You are also making sure you put question marks at the ends of questions and periods at the ends of statements.
The next step is to check your word choice and spelling. You want to be sure that you have used the correct words for your intended meaning, so you want to be sure that you haven't used a two when you need a too. Be sure to double check the spelling of any word you often misspell and look up any word you are unsure of. If you are word processing, use the spell check on your computer to help you with your possible spelling mistakes.
