The worksheet allows students to hone their skills in using commas in lists or series. It begins with a sample sentence and then presents 15 sentences about an interesting character named Wesley, the fancy Oxford Comma. Students are tasked with correcting each sentence by inserting two or more commas.

Commas in a series are used when listing three or more items in a sentence. You place the comma after each item on the list except for the last one. For example, in the sentence "I need to buy apples, bananas, and grapes," the commas separate each item in the list to make it easier to understand.

1. Read the sentence: Understand the context and identify the items or phrases in the series.

2. Find the series: Identify what is being listed. This could be words, phrases, or clauses. Make sure you separate each item in the series with a comma.

3. Use commas: Place a comma after each item in the series. The only one that can be tricky is the one that comes before the conjunction (and, or, nor), also known as the serial comma or Oxford comma. This comma is considered optional in most English styles but may help clarify.

4. Check your work: Reread the sentence to ensure it makes sense and that the commas are correctly placed.

Example:

Incorrect: I like apples bananas and oranges.

Correct (without Oxford comma): I like apples, bananas and oranges.

Correct (with Oxford comma): I like apples, bananas, and oranges.

The character of 'Wesley the fancy Oxford Comma' serves as a fun and engaging way to learn and remember the function and importance of the Oxford comma.
