Essentially, a classroom number talk is a discussion around a particular problem. The teacher displays the problem, and the kids are first given a chance to solve it independently. Then, the teacher takes and records all answers (both correct and incorrect) so the class can discuss the strategies used. So, what's the teacher's role in a number talk?
When discussing a problem, ideally the teacher's role is that of facilitator, but it's going to take some time to get there. Kids (especially younger kiddos) are going to need lots of modeling and practice with how to respond to one another and ask questions. I love this pin of math talk discussion starters.

Being purposeful in selecting the problem is also an important role for the teacher. If the goal is to discuss various ways to solve 3 addend problems, the numbers selected for the problem should assist that goal. For example, the problem 3 + 7 + 3 would allow students to use doubles (and then near doubles when solving 6+7), finding a ten, or counting up. If the teacher wanted to focus on borrowing from one addend and giving to another, a problem like 8 + 5 + 3 might be helpful, because the student could take 2 away from the 5 and give it to the 8 to make a ten, leaving them with 10 + 3 + 3.
Sherry Parrish also recommends that teacher's have a specific spot in their classroom where they hold their number talks. Mine is on our carpet, as it's the place for students to be close to one another. She also recommends that teacher's have something to record student thinking, whether that be up on the Smartboard or on chart paper. Posting student strategies as anchor charts around the room can help keep students accountable during that time.
So how do I incorporate number talks?
I have to admit, I did a better job with this at the beginning of the year than I have lately. Mostly because I started the year off doing a LOT of subitizing and activities from my number sense pack. We had some great discussions, even as beginning first graders, about the different ways that we saw numbers. I have continued number talks occasionally in guided math, but have not done them whole group in awhile. What I would like to start doing is creating a bank of problems to use for my number talks. I think that having the problems ready to go will help me be more consistent with implementing number talks throughout the year.
So, have YOU implemented number talks in your classroom? I'd love to hear how it's going and if you have any tips for implementing them consistently. Feel free to share resources that you've found helpful as well. :)
Happy teaching!
