Rewrite all the sentences in the paragraph so they are in list form, with space between each sentence. If you have a very large paragraph, use a pen to mark a vertical line separating each sentence.
Examine each sentence in the list or paragraph to fix run-on sentences. Run-on sentences are two independent sentences with no punctuation between them. An example is "I have two dogs I have two cats." Fix this to read, "I have two dogs. I have two cats." You can also add "and/or" to correct sentences.
Use different colored pens to highlight and group like sentences together to decide which should remain in the paragraph. Sentences that are part of a single idea create one paragraph. If the topic or idea changes, a new paragraph should begin. If a sentence does not belong in any group, mark a line through it and exclude it from consideration.
Rewrite a new paragraph with the grouped sentences that fit a similar idea. Transfer the other group of sentences to form a second and third paragraph. Re-read to confirm the sentences flow together and read well.
