Learn where the little comma mark goes when you write a date or list words in a row!
Have you ever tried to read a really long word without any spaces? It would be so hard! A long time ago, people figured out that writing needs little marks to help readers know when to pause. One of those little marks is the comma. It looks like a tiny curved tail: ,
The comma helps us read sentences the right way. Without commas, words can get all jumbled up and confusing. Let's look at how people started using commas!
So the big question is: Where does the comma go? In this lesson, you will learn two important places where commas belong. Ready? Let's go!
In first grade, you need to know two special comma rules. These rules are easy to learn and you will use them all the time when you write!
Let's look at a picture that shows where commas go in a date. The comma sits right between the day number and the year. It is like a little bridge that connects them!
See how the comma sits right after the number 15 and before the year 2025? The month name comes first, then the day number, then the comma, then the year. Easy!
Now let's see a picture of a list with commas:
Look at the pink commas! Each one comes after a word in the list. The word "and" tells us the last item is coming. You can see that with three items, we need two commas.
When you write a date, you write the month name first. Then you write the day number. Then you put a comma. Then you write the year. Here is the pattern:
Here are more examples:
September 5, 2024
December 25, 2023
My birthday is June 10, 2018.
When you write three or more words in a row, those words make a series. A series is just a fancy word for a list! You put a comma after each word — but not after the last word. The word "and" or "or" connects the last two things.
Here are more list examples:
I can run, jump, and swim.
She has a dog, a cat, and a fish.
Do you want red, blue, or green?
Notice that in each list, we have three items and two commas. If you had four items, you would use three commas!
I ate toast, eggs, fruit, and milk.
Let's look at different kinds of lists and dates so you can see commas in action!
| Type | Example | How Many Commas? |
|---|---|---|
| Date | May 3, 2025 | 1 comma |
| List of 3 things | cats, dogs, and birds | 2 commas |
| List of 4 things | red, blue, green, and yellow | 3 commas |
| List of actions | run, hop, and skip | 2 commas |
| List with "or" | cake, pie, or cookies | 2 commas |
See the pattern? For a date, you always use just one comma. For a list, count the items. The number of commas is always one less than the number of items!
Let's practice putting commas in the right places together!
Here are some things to watch out for when you use commas!
| ❌ Wrong | ✅ Right | Why? |
|---|---|---|
| June 1 2025 | June 1, 2025 | A comma goes between the day and the year. |
| I like cats dogs and fish. | I like cats, dogs, and fish. | Put commas between the items in a list. |
| I like cats, and fish. | I like cats and fish. | Only two items — no comma needed! |
| red, blue, and, green | red, blue, and green | Don't put a comma after "and." |
You are learning two comma rules right now. But did you know there are even more comma rules you will learn as you grow up? Here is a sneak peek!
| What You Know Now (1st Grade) | What You'll Learn Later |
|---|---|
| Commas in dates: July 4, 2025 | Commas in addresses: Austin, Texas |
| Commas in a list: red, blue, and green | Commas after greetings: Dear Mom, |
| Lists of single words | Lists of groups of words (phrases!) |
You are building a strong base for writing! Every time you use a comma the right way, you are getting ready for even bigger and better sentences. Great job! 🌟

Today you learned two important comma rules! First, when you write a date, you always put a comma between the day number and the year, like this: July 4, 2025. Second, when you write a list of three or more words, you put a comma after each word except the last one, like this: red, blue, and green.
Remember, commas are like little pause signs that help your reader understand your writing. You only use commas in a list when there are three or more items — two items with "and" don't need a comma. Keep practicing, and you will be a comma expert in no time! 🎉
