Build writing stamina with sentence starters is one of the biggest challenges elementary teachers face. Students often have ideas but struggle to get started—or stop writing after just a sentence or two. Sentence starters can be a powerful tool to help students write longer, stay focused, and feel more confident as writers. Read on for ideas for writing instruction K-5.
I created this teacher-to-teacher guide to explain how to use sentence starters for writing intentionally to build writing stamina without limiting student voice or creativity.
Why Writing Stamina Is Hard for Elementary Students
Many students stop writing not because they’re “done,” but because:
- They don’t know how to start a sentence
- They run out of academic language
- Writing feels overwhelming or intimidating

I believe writing stamina is really about sustained thinking, not speed. Sentence starters help remove the barrier of how to begin so students can focus on what they want to say.
How Sentence Starters Support Writing Stamina
Sentence starters work because they:
- Reduce cognitive load
- Provide clear language models
- Increase student confidence
- Keep pencils moving
When students don’t have to struggle with sentence structure, they’re more likely to write for longer periods of time—and with greater detail.
What Sentence Starters Are (and Are Not)
Sentence starters for writing stamina ARE:
- Language scaffolds
- Confidence builders
- Temporary supports
Sentence starters for writing stamina are NOT:

- Fill-in-the-blank worksheets
- Permanent crutches
- The end goal of writing instruction
The goal is independence. Sentence starters are a bridge that helps students get there.
Sentence Starters That Actually Help Students Write Longer
Opinion Writing Sentence Starters

Teaching tip: Post just 3–4 options at a time to avoid overwhelming students.
Narrative Writing Stamina Sentence Starters
Great for personal narratives and storytelling.
- One day, I decided to…
- At first, I felt…
- Suddenly, something unexpected happened…
- In the end, I learned…
Stamina builder: Ask students to use two different sentence starters in one piece of writing.
Informational Writing Sentence Starters

- For example…
- In conclusion…
These sentence starters support both content learning and writing development.
Reflection & Journal Sentence Starters
Excellent for low-pressure writing and reluctant writers.
- This reminds me of…
- I used to think…, but now I think…
- I wonder why…
- Something that surprised me was…
These are especially helpful for English learners and students who need extra language support.

How to Use Sentence Starters Without Limiting Student Writing
Start Small
- Begin with 5 minutes of writing
- Model using one sentence starter
- Praise effort, not length
Gradually Increase Writing Time
- Add 2–3 minutes every few days
- Keep expectations consistent
- Track progress with a visible stamina chart
Offer Student Choice
Instead of saying “Use this sentence starter,” try:
“Choose a sentence starter that helps you today.”
Choice leads to ownership—and stronger writing stamina.
When and How to Fade Sentence Starters
As students grow more confident:

- Remove sentence starter sheets from desks
- Keep them on anchor charts
- Reference them only when needed
You’ll know sentence starters are working when students:
- Begin writing independently
- Write longer pieces
- Ask for more writing time
Final Thoughts for Elementary Teachers
Writing stamina doesn’t develop overnight. But when students feel supported and successful, they’re willing to stick with writing longer each day.
Sentence starters don’t make writing easier—they make writing possible.
And once writing feels possible, stamina follows.
