Number Talks in 1st Grade: How to Build Number Sense with Daily Math Routines

If you’re looking for a simple way to strengthen math thinking in your classroom, number talks are one of the most effective (and low-prep) routines you can start using today.

In this post, you’ll learn:

• What number talks are
• Why number talks are important in 1st grade
• Simple tips for getting started
• A printable resource to make implementation easier

What Are Number Talks?

Number talks are short, daily math discussions that encourage students to solve problems mentally and share their thinking out loud. They are not about speed or just getting the right answer, number talks focus on:

• Mental math strategies
• Flexible thinking
• Explaining reasoning
• Listening and comparing different approaches

These routines typically take just 5–10 minutes and are done without paper or pencil. Students are encouraged to “think in their heads” and show a silent signal (like a thumbs up) when they’re ready to share.

Why Are Number Talks Important in 1st Grade?

First grade is a crucial time for developing number sense, the ability to understand and work with numbers flexibly. Number talks help students:

• Build fluency with addition and subtraction facts
• Use strategies like doubles, making 10, and counting on
• Develop mathematical language and communication
• Gain confidence by hearing multiple ways to solve a problem

Best of all, number talks create a safe space where mistakes are seen as learning opportunities.

What Do Number Talks Look Like?

Here’s a simple example:

Teacher: “If you have 3 apples and get 4 more apples, how many apples do you have now?” Show a quiet thumbs up when you’ve figured it out in your head.”

Then the teacher invites a few students to share how they solved the problem.

• “I did 3 + 3 = 6 because I know that is a doubles fact, then I added the leftover 1 to get to 7.
• “I thought of 4 + 4 = 8, then I took away 1, so I know the answer is 7.”
• “I added using my fingers and counted on from 3… 4, 5, 6, 7.”

The class discusses these strategies. Students compare and notice patterns, developing a deeper understanding of how numbers work.

How to Start Number Talks in Your Classroom

Starting number talks in 1st grade doesn’t have to be complicated. Here’s a simple routine to follow:

1. Choose one math problem (start with addition or subtraction within 10).
2. Ask students to solve it mentally.
3. Encourage quiet thinking time and silent signals when they’re ready.
4. Invite students to share strategies—and write them on the board if helpful.
5. Facilitate a discussion about different approaches, encouraging respectful listening.

Start with just a few problems per week and gradually build consistency. You’ll see students become more confident in sharing their thinking and trying new strategies.

Free Number Talk Prompts

If you’re just getting started, here are a few prompt types that work great in 1st grade:

• “What is 7 + 8? Can you explain your strategy?”
• “What do you notice about the numbers 9 + 1 and 10?”
• Show a ten frame or number bond and ask: “What number is missing?”
• Use a number sentence with a missing addend: “__ + 4 = 10”

Visuals are especially helpful for young learners!

Final Thoughts

Number talks are one of the most powerful tools for helping 1st grade students become flexible, confident problem solvers. They don’t require a lot of prep or materials—but they deliver big results in terms of student engagement, mental math, and number sense development.
