Season 1 | Episode 15 – Productive Ways to Build Fluency with Basic Facts

Guest: Dr. Jennifer Bay-Williams 

Mike Wallus: Ensuring students master their basic facts remains a shared goal among parents and educators. That said, many educators wonder what should replace the memorization drills that cause so much harm to their students' math identities. Today on the podcast, Jenny Bay-Williams talks about how to meet that goal and shares a set of productive practices that also support student reasoning and sense making. 

Mike: Welcome to the podcast, Jenny. We are excited to have you. 

Jennifer Bay-Williams: Well, thank you for inviting me. I'm thrilled to be here and excited to be talking about basic facts. 

Mike: Awesome. Let's jump in. So, your recommendations start with an emphasis on reasoning. I wonder if we could start by just having you talk about the ‘why’ behind your recommendation and a little bit about what an emphasis on reasoning looks like in an elementary classroom when you're thinking about basic facts. 

Jenny: All right, well, I'm going to start with a little bit of a snarky response: that the non-reasoning approach doesn't work. 

Mike and Jenny: ( laugh ) 

Jenny: OK. So, one reason to move to reasoning is that memorization doesn't work. Drill doesn't work for most people. But the reason to focus on reasoning with basic facts beyond that fact, is that the reasoning strategies grow to strategies that can be used beyond basic facts. So, if you take something like the making 10 idea—that nine plus six, you can move one over and you have 10 plus five—is a beautiful strategy for a 99 plus 35. So, you teach the reasoning upfront from the beginning, and it sets students up for success later on. 

Mike: That absolutely makes sense. So, you talk about the difference between telling a strategy and explicit instruction. And I raised this because I suspect that some people might struggle to think about how those are different. Could you describe what explicit instruction looks like and maybe share an example with listeners? 

Jenny: Absolutely. First of all, I like to use the whole phrase: ‘explicit strategy instruction.’ So, what you're trying to do is have that strategy be explicit, noticeable, visible. So, for example, if you're going to do the making 10 strategy we just talked about, you might have two ten-frames. One of them is filled with nine counters, and one of them is filled with six counters. And students can see that moving one counter over is the same quantity. So, they're seeing this flexibility that you can move numbers around, and you end up with the same sum. So, you're just making that idea explicit and then helping them generalize. You change the problems up and then they come back and they're like, ‘Oh, hey, we can always move some over to make a 10 or a 20 or a 30’ or whatever you're working on. And so, I feel like, in using the counters, or they could be stacking unifix cubes or things like that. That's the explicit instruction.

Jenny: It's concrete. And then, if you need to be even more explicit, you ask students in the end to summarize the pattern that they noticed across the three or four problems that they solved. ‘Oh, that you take the bigger number, and then you go ahead and complete a 10 to make it easier to add.’ And then, that's how you're really bringing those ideas out into the community to talk about. For multiplication, I'm just going to contrast. Let's say we're doing add a group strategy with multiplication. If you were going to do direct instruction, and you're doing six times eight, you might say, ‘All right, so when you see a six,’ then a direct instruction would be like, ‘Take that first number and just assume it's a five.’ So then, ‘Five eights is how much? Write that down.’ That's direct instructio
