“I need a worksheet for students to learn the following concepts with a substitute teacher: We use commas to separate items in a list or series when the items are simple and have no punctuation within them. Here’s an example: Our most popular pizza includes mozzarella cheese, bacon, and banana peppers. The comma used before the conjunction (in this case “and”) is called an “Oxford comma.” It gets its name from the Oxford Style Manual. This comma can be optional, but it is typically preferred. Without the Oxford comma, the sentence would look like this: Our most popular pizza includes mozzarella cheese, bacon and banana peppers. We use commas to separate items in a list but also anything else that comes in a series. Here’s an example: First, we make the dough from scratch, then we bake it for five minutes to make it crispy, and finally, we add the toppings and bake it for another 10 minutes. Sometimes we need to use semicolons to separate items in a series. We use semicolons when one or more items are more complex and already involve a comma on their own. Some examples include listing cities and states together, people with their titles, or multi-item sections. Here are some examples: Our food truck has served customers in Albany, New York; Cherry Hill, New Jersey; Philadelphia, Pennsylvania; and Mystic, Connecticut. Our team includes Jasmine, the cook; Hawthorne, the server; and Lily, the advertiser. You can create a personal pizza with mozzarella, Romano, or cheddar cheese; pepperoni, sausage, or bacon; olives, peppers, or onions; and basil, parsley, or oregano. Note that because the commas in these types of lists can complicate the sentence, we always need a final semicolon before the conjunction. It is not optional like the Oxford comma.”
