You ask students to turn and talk about their math thinking.
And then you hear…
“Same.”
“I agree.”
“I dunno.”
Or worse, complete silence.
If that sounds familiar, I feel your frustration. Math talk can be tricky, especially in upper elementary classrooms where students are still learning how to explain their thinking clearly.
The good news? Students can learn how to talk about math. But most of them need more than a quick “turn and talk” direction. They need examples, sentence stems, practice, and clear expectations for what a strong math discussion sounds like.
Let’s look at a few simple ways to get students talking about math in a way that is actually helpful.
Why Math Talk Matters
Math talk helps students do more than share an answer. It gives them a chance to explain how they solved a problem, listen to other strategies, ask questions, and build a deeper understanding of the math.
When students talk about math, they start to notice things like:
- There can be more than one way to solve a problem.
- A mistake can help the class learn something important.
- Explaining a strategy helps make the thinking clearer.
- Listening to another student can help them understand a new method.
But here’s the catch: students do not always know how to do this naturally.
Some students are nervous. Some are not sure what to say. Some give one-word answers because they think agreeing is enough. Others may jump straight to “you’re wrong” because they have not learned how to disagree respectfully.
That’s why math talk needs to be taught like a classroom routine.
Start by Teaching What Math Talk Sounds Like
Before students can have strong math conversations, they need to know what kinds of things mathematicians say.
You might start by explaining that Math Talk is when students use words to:
- explain their thinking
- share ideas
- use math vocabulary
- ask questions
- build on someone else’s idea
- agree with a reason
- disagree respectfully
- compare strategies
This helps students understand that math talk is not just “tell your partner your answer.” It is a way to think, listen, and respond.
A simple anchor chart or set of Math Talk posters can be helpful because students need a visual reminder they can refer back to during discussions.
Give Students Sentence Stems
One of the easiest ways to improve math discussions is to give students sentence stems.
Sentence stems help students start their response when they are not sure what to say. They also make the conversation more focused.
| Instead of saying: | Students can say: |
| “I agree.” | “I agree because…” |
| “I don’t get it.” | “Can you explain that?” |
| “We did it different.” | “We solved it differently by…” |
These small changes make a big difference because students have to give more detail.
Here are a few helpful math talk sentence stems to try:
To explain thinking:
- “I solved it by…”
- “My strategy was…”
- “I know because…”
To ask questions:
- “Can you explain that?”
- “How did you get that answer?”
- “Why did you choose that strategy?”
To agree with a reason:
- “I agree because…”
- “That makes sense because…”
- “I got a similar answer when…”
To disagree respectfully:
- “I see it another way…”
- “I got a different answer because…”
- “Can we look at this part again?”
To compare strategies:
- “Both strategies work because…”
- “We solved it differently by…”
- “This strategy is helpful because…”
You do not have to introduce every sentence stem at once. In fact, it is usually better if you don’t.
Start with one or two stems. Practice them. Model them. Then add more as students get comfortable.
Model the Difference Between Weak and Strong Math Talk
Students often need to see what better math talk looks like.
You can do this with a simple “instead of saying / try saying” lesson.
For example:
| Instead of saying: | Students can say: |
| “That’s wrong.” | “Can we look at this part again?” |
| “I agree.” | “I agree because…” |
| “I just know.” | “I know because…” |
This type of quick modeling helps students understand that their words matter.
It also gives them a safer way to participate, especially when they are confused or when they disagree with a classmate.
Teach Students How to Ask Good Questions
A good math question can keep the conversation going.
But students need help understanding what makes a question useful.
For example, these questions usually do not lead to much discussion:
- “What’s the answer?”
- “Are you done?”
- “Is this right?”
Better math questions sound like:
- “How did you get that answer?”
- “Can you explain that step?”
- “Why did you choose that strategy?”
- “What does this number represent?”
- “Can you show that another way?”
These questions help students focus on the thinking, not just the answer.
One simple activity is to give students a few sample questions and have them decide which ones help the math conversation the most.
Then talk about why.
Make Respectful Disagreement Part of the Routine
Disagreeing in math should not feel rude. It should feel like part of the learning process.
Students need to know that respectful disagreement focuses on the math, not the person.
You can teach this with a simple reminder:
We question the strategy, step, or answer. We do not criticize the person.
Helpful stems include:
- “I see it another way…”
- “I got a different answer because…”
- “Can we check this step?”
- “Can we look at this part again?”
This is especially useful during problem solving because students will not always get the same answer. When that happens, you want them to compare their thinking instead of shutting down the conversation.
Help Students Compare Strategies
Comparing strategies is one of the best parts of math talk.
It helps students see that there may be more than one way to solve a problem. It also helps them think about which strategy is more efficient or easier to understand.
But students often need help moving beyond:
“We did it different.”
A stronger response would be:
“Our strategies are different because I used a picture, and you used an equation.”
Or:
“Both strategies work because they show equal groups.”
When students compare strategies, encourage them to look for:
- what is the same
- what is different
- what model was used
- what equation was used
- which strategy was more efficient
- how both strategies connect to the problem
This helps students become more thoughtful problem solvers.
Keep Math Talk Short at First
Math talk does not need to take over your whole lesson.
In fact, short practice is usually better when students are first learning the routine.
Try something simple like:
- Students solve one problem.
- Partner A explains their strategy.
- Partner B asks one question or agrees with a reason.
- Switch roles.
- Share one strategy with the class.
That’s it.
You can also give students a quick exit ticket after the discussion. Keep it simple so the writing does not become the main task.
For example:
Today I used Math Talk to:
☐ explain my thinking
☐ ask a question
☐ agree with a reason
☐ compare strategies
One sentence stem I used:
This gives you a little accountability without making the activity time-consuming.
Use Visual Reminders
Even after students learn the sentence stems, they will still need reminders.
That’s where posters, bookmarks, speech bubbles, and bulletin board displays can help.
A Math Talk display gives students a place to look when they get stuck. A bookmark or desk strip gives them a smaller reference they can use during partner work or independent problem solving.
The key is to make the reminders easy to use.
Students should be able to quickly find a stem like:
- “I agree because…”
- “Can you explain that?”
- “I solved it by…”
- “Both strategies work because…”
You do not need a huge display to make Math Talk work. Even a small set of posters or sentence stems can make a big difference when students use them often.
Make Math Talk Part of Your Routine
The best way to get students talking about math is to make it normal.
You can use Math Talk during:
- warm-ups
- problem solving
- partner work
- small groups
- test prep review
- error analysis
- math centers
- whole-group discussions
You do not have to use it every single day in a formal way. Just look for small moments where students can explain, ask, agree, disagree, or compare.
Over time, those small moments help students become more comfortable sharing their thinking.
Final Thoughts
Getting students to talk about math takes practice.
Most students are not going to go from shrugging their shoulders to a detailed explanation overnight. But with sentence stems, modeling, visual reminders, and short practice opportunities, they can learn how to have better math conversations.
Start small.
Pick one sentence stem. Model it. Practice it. Add another one when students are ready.
Before long, your students will have more tools for explaining their thinking, listening to classmates, and talking through math in a way that actually helps them learn.
