I always get a chuckle out of the “Punctuation saves lives” memes and signs. They usually go something like this:
Let’s eat, Grandpa!
Let’s eat Grandpa.
It may seem silly, but it is a great example of why proper use of commas in a sentence can make all the difference! Put a comma in the wrong spot, or have no comma at all, and the meaning of the sentence is completely changed. Let’s take a closer look on how commas are used in 2nd grade grammar.

What is a comma?
A comma is a punctuation mark that separates words in a sentence. A comma indicates that the reader should take a pause.

Teaching Comma Rules in 2nd Grade
The comma has many uses in English grammar. 2nd grade learners will focus on these uses of commas:
1. Separating words in a list
When there are three or more nouns in a list in a sentence, they should be separated with a comma.
Example: Grandpa wants to ride the Ferris Wheel, swings, and roller coaster.
2. In greetings and closings of a letter

When writing a friendly letter, a comma should come after the greeting and the closing.
Example:
Dear Grandpa,
I had so much fun at the carnival.
Love,
Molly
3. When writing a date
Commas help separate important parts of a date. When writing a date, there should be a comma after the day of the week, and after the numerical date.
Example: Election Day is Tuesday, November 8, 2022.

4. To separate a city and state
Separate a city and state in a sentence with a comma.
Example: We will travel to Philadelphia, Pennsylvania.
Tactile ways to Teach Commas in 2nd Grade
Many learners love hands on, tactile activities to reinforce a new skill. When teaching commas, write a sentence on large sentence strips. Then have students use a piece of elbow macaroni to show where the comma belongs. Once students have practiced on several pre-written sentences, have them practice writing their own sentence. Glue down the elbow macaroni on their sentence strips, and hang the new sentence art around the room. You can also use play-doh or a fingertip dipped in paint to form commas in this activity, too.
