Manipulating Sentences to Reinforce Grammar Skills

I am going to try this lesson with another teacher as a combined lannguage arts collaboration however, I am concerned about how to approach this subject with students who unfortunately fall into the basic and below basic category. I want to use several sentences and paragraphs to preclude this one in hopes that by the time we reach this level, they will have accomplished some things they need to know. I would like to ask if there is an 'answer sheet' per se that will give some ideas as to what the sentences might look like from various perspectives. I have tried one of them, but would like to see some others. Can you share this information or either a website? Thank you very much.
