Using Commas interactive worksheet - Free Printable

Let's go through each sentence and determine where the commas should be placed. The main rule we're applying here is the Oxford comma (also known as the serial comma), which is used before the conjunction (usually "and" or "or") in a list of three or more items. While its use can vary by style guide, it's often recommended in formal writing to avoid ambiguity.
