Why Wait Time Matters in Math Talks

Awkward silences can be uncomfortable, and as teachers, we often rush to fill them. It’s easy to feel the urge to take answers quickly, but in math talks (also called number talks or math routines), silence is a powerful tool to create deeper learning in math.

During Math Talks and Number Talks (aka mental math activities), students need time to process and think. When we jump in too soon, eager to get the conversation going, we may unintentionally signal that speed is more important than thoughtfulness. The reality is, most of the class still needs time to figure out their solutions when we take those first few raised hands.

This used to be me—I’d rush to take answers as soon as eager hands went up. Silence made me nervous, and I wanted to keep things moving. But then I realized that in math, that silence isn’t awkward at all. For students, it’s a signal: Math takes thinking especially if our goal is for kids to have deeper learning in math.

Embracing the Silence

Not all math problems are solved in a flash. Some students need a lot of time to think and work through their strategies. And that’s okay! In fact, it’s essential.

Think-time is critical during math talks because students are solving problems mentally. They need that quiet space to process, strategize, and think deeply. When we rush to take answers, we prioritize speed over understanding. By waiting—sometimes longer than feels comfortable—we ensure that every student has the time they need to engage with the math.

Why Think-Time Matters

In classrooms where quick answer-getters are always called on, many students fall into the habit of letting others do the thinking for them. They know a “faster” student will answer, so why try? But when you make it clear that you’re willing to wait for everyone to think, students realize you expect them to try and engage with the problem.

Let’s look at an example: Sandy is a student who takes a long time to think through math problems. First, she needs to choose a strategy, then work through it—sometimes counting on her fingers or using other strategies. When given enough time, Sandy can arrive at the right answer and feel proud of her thinking.

But what happens when her teacher moves too quickly? Sandy doesn’t get a chance to finish. She starts to believe she’s not fast enough, so she gives up before she even starts. Soon, she feels insecure about her math abilities, even though she’s fully capable of solving the problem if given the time.

The Harm of Rushing

Without adequate think-time, we send the message that quick answers are more important than thoughtful ones. Slower students begin to feel inadequate—not because they lack ability, but because they aren’t given the time they need to fully engage.

When we allow students ample time to think, we tell them we value deep thinking and problem-solving, not just fast answer-getting. Math is about exploring, strategizing, and figuring things out, not racing to the answer.

Encouraging Deeper Thinking

So, what about the students who solve the problem quickly? Encourage them to find multiple strategies for solving the same problem. This strengthens their flexible thinking and reinforces that math isn’t about speed—it’s about understanding. By finding different ways to solve a problem, they gain a deeper understanding of mathematical concepts and see the value in taking their time.

Conclusion

Giving students enough think-time during math talks is essential for their growth, confidence, and deeper learning in math. Whether they’re quick or need extra time, all students deserve the opportunity to engage deeply with the material. So next time you’re leading a number talk or mental math routine, embrace the silence. Give your students the time they need to think—because deep thinking leads to real mathematical understanding.
