Teaching commas in a series seems like a quick grammar lesson, until students start writing. Some kids forget the commas entirely. Others sprinkle commas everywhere just in case (with as much enthusiasm as they sprinkle those sugar crystals on their Christmas cookies!) And many get confused about what actually counts as a “series” in the first place.
But with a little instruction and some hands-on practice, your kids can master it in no time.
Here, we’re sharing some engaging ways to teach commas in a series, plus a few ready-to-use resources to help reinforce the skill all year long!
Looking for a fun, festive holiday-themed activity for your kids to practice commas in a series? Check out our Commas in a Series Build-a-Sentence Buffet!
Start With a Simple, Clear Mini-Lesson
Before diving into activities, I like to begin with a quick mini-lesson and guided interactive notebook activity so the kids have something to reference when they’re working independently later on.
Explain that a series is simply a list of three or more things within a sentence. Then show an example or two:
The library is hosting a children’s story time, game nights, and a reading competition this summer.
Students may either choose spaghetti, hot dogs, or hamburgers for lunch today.
I start by displaying these sentences with no commas and let students explain why commas help the sentence make more sense. Then together, we underline the separate items in the series and add the commas. A tiny discussion here goes a long way when we switch to independent practice!
Fun Ways to Teach Commas in a Series
Students learn best when they’re doing something hands-on, silly, or creative. Here are several engaging activities that help reinforce the rule after we’ve covered it in our notebooks.
1. Build-a-Sentence Buffet
Lay out sets of vocabulary cards for categories like foods, animals, winter items, or anything tied to your current unit. Students can select or randomly choose 3–5 cards and write a sentence that includes all of them, using commas correctly. For students who need more support, you can also provide the sentence starters here and let them complete the sentence with the items they selected.
For example: “The penguin grabbed a scarf, a sled, and a cup of cocoa.”
This is a go-to activity for writing centers or early finishers.
2. Classroom Scavenger Hunt Lists
Give students 60 seconds to list three or more things they see around the classroom. Then challenge them to turn each list into a complete sentence:
“I spotted notebooks, crayons, and backpacks by the door.”
You could even turn this into a race for those extra-competitive kids in your group, or assign specific categories for a little challenge!
3. Teacher vs. Students Comma Challenge
Project sentences, some correct, and some with missing commas. Students earn a point every time they catch a mistake you “accidentally” wrote. This playful reversal helps them explain why the comma belongs there, and you know they love correcting us!
4. Nature or STEM Observation Sentences
If you use nature journaling, Science Scouts, or science materials in your classroom, pull them into writing! Students can observe an object or picture and write a descriptive sentence using a series, like “The leaf was red, brown, and speckled with gold.” This works great as a cross-curricular warm-up.
Independent Practice: Build Confidence!
Once students understand the skill, we shift to more structured practice. This helps them apply the rule in their own writing and on assessments.
Skill-Specific Revising & Editing Task Cards
Our Skill-Specific Revising and Editing Commas in a Series Task Cards include 24 multiple-choice questions that focus specifically on commas in a series. Students read sentences and choose the correct revision, just like they would on their big tests!
These are perfect for:
Literacy centers
Morning work
Small groups
Quick end-of-day review
Because the questions are short, students don’t get bogged down, and the repetition really cements the rule.
Skill-Specific Revising and Editing Comprehension Passage
To shift the skill into real reading context, we also created a short half-page passage with multiple-choice questions written just like the ones on state tests. Students practice identifying whether a sentence uses commas correctly and choosing the best revision.
This works great for a quick check, test-prep warm-ups, or a tool for intervention groups. Get the FREE download here!
Sentence Starters to Encourage Practice
Repetition is key, so here are a few quick prompts you can use for warm-ups or journal time:
On the field trip, we packed…
During winter break, I want to…
My favorite animals are…
For the party, we decorated with…
At the store, I bought…
Sentence starters make it easy for students to naturally include a series without overthinking it.
Teaching commas in a series doesn’t have to be a dry grammar lesson. Hands-on activities and repeated practice help your kids start applying the rule automatically in both writing and reading!
