Math talk culture starts long before students can explain a strategy or solve a word problem. In fact, if you’re waiting until your students “know enough math” to start talking about math, you’re already behind. I know that sounds a little dramatic, but hear me out.
One of the biggest mistakes I see teachers make is treating math talk as something they add later in the year. The problem is that students don’t suddenly wake up in October ready to explain their thinking. Just like any classroom routine, math talk has to be taught, modeled, and practiced from the very beginning. That’s why during the first week of school, I’m not just teaching math. I’m building a math talk culture.
Before we dive into standards and curriculum lessons, I help my students build that math talk culture. And the best part? None of this takes weeks to implement. Let me show you exactly what I do.
Build Math Talk Culture Day 1: What Is a Mathematician?
If you’ve ever asked first graders what a mathematician is, you’ve probably gotten answers like:
- “A really smart person.”
- “Someone who does hard math.”
- “My older brother.”
- “A teacher.”
Rarely do they point to themselves. And honestly, that’s exactly why I start here. Before I teach addition, subtraction, place value, or even open our math curriculum, I want my students to start seeing themselves as mathematicians.
I begin with a lesson called What Is a Mathematician? We brainstorm what mathematicians are, what they do, and what they use. At first, my students are usually pretty hesitant. They’re trying to figure out the “right” answer and looking at me for approval. But after a few minutes, something shifts. Students start sharing ideas more freely. They begin building on each other’s thinking. They realize there isn’t just one way to think about math.
By the end of the lesson, many students have gone from thinking mathematicians are people somewhere out there to realizing they already do many of the same things mathematicians do every day. That’s when something special happens. Their identity starts to shift. When students start believing they are mathematicians, they’re willing to share ideas, take risks, and explain their thinking. That’s exactly the kind of math talk culture I want from Day 1.
Build Math Talk Culture Day 2: Where Can We Find Math?
Now that we’re starting to build that mathematician mindset, it’s time to help students realize that math isn’t something that only happens during math block. Math is everywhere.
For this lesson, I like reading books such as Math at the Store and Math at the Airport. As we read, we talk about all the ways people use math in real life. Then I send my students on a mission around the classroom. Working with a partner, they look for examples of math all around them. They might notice numbers on our calendar, shapes in the room, patterns on classroom materials, or opportunities for counting and measuring. And let me tell you, once they start looking, they can’t stop finding examples.
The purpose of this lesson is simple: I want students to understand that math isn’t just something we do on worksheets. Math is part of our everyday lives. When students start noticing math in the world around them, they become more invested in learning it. Before I’ve taught a single standard, my students are already discussing mathematical ideas. That’s a win in my book.
Establishing Math Talk Norms
After those first two lessons, it’s time to talk about what math discussions should actually look and sound like in our classroom. Teacher bestie, don’t skip this step. You may be tempted to start the curriculum, but establishing math talk norms early will make your math lessons run so much smoother all year long.
I use anchor charts to introduce our expectations for math discussions. One thing I love doing is having students help create these charts. Instead of me standing at the front of the room telling them all the rules, we brainstorm together. Students help generate ideas about how mathematicians communicate and collaborate.
The best part is that this doesn’t need to take an entire math block. I usually attach it to our “Where Can We Find Math?” lesson, and it only takes a few extra minutes.
The Next Few Days: Introducing the 8 Math Practice
Once my students see themselves as mathematicians and understand that math is all around them, it’s time to introduce the habits that mathematicians use every day. That’s where the 8 Mathematical Practices come in. Over the next several days, I introduce one math practice at a time. We talk about what it means, what it looks like, and why it matters.
I don’t just read a poster and call it a day. We discuss examples and practice together. Then we do a simple activity that helps students experience the math practice in action. These lessons are short, meaningful, and easy to fit into those first days of school.
One thing I love about this approach is that I don’t have to choose between building a math talk culture and starting my curriculum. I can do both. While I usually wait until after the first full week of school to officially begin Lesson 1 of my math curriculum, these mini-lessons fit right alongside our regular math instruction.
Why Math Talk Culture Matters
Creating a math talk culture isn’t one more thing to add to your already overflowing teacher to-do list. It’s the foundation that everything else is built on. When students feel comfortable sharing their thinking, they become more confident learners. They develop deeper mathematical understanding because they’re talking through ideas instead of simply memorizing procedures.
The reality is that most math curriculums focus on teaching standards. That’s important, of course. But they don’t always teach students how to discuss mathematics. That’s the piece we have to intentionally build. And teacher bestie, it doesn’t have to be complicated.
If you’d like everything planned out for you, my Mathematician Unit walks students through these exact lessons and activities while helping you build a strong math talk culture from the very beginning of the school year.
And if you only take one thing away from this post, let it be this: Don’t wait to start math talk. Start on Day 1. Because the students who confidently explain their thinking in April are usually the same students who were encouraged to share their ideas in August. You’ve got this!
