This worksheet answers the question "Ugh! Why do commas matter?" Students are given 5 sentences that use commas (or don't use commas) improperly. Without the proper use of commas, these sentences are likely found in a scary story. With the commas, these sentences are quite normal. This worksheet is meant to be fun and instructive. I hope your students will get a laugh out of it as they learn to use commas properly.
