Latest / Rounding Up / I Have, You Need: The Utility Player of Instructional Routines with Kim Montague
Transcript
- 0:03In sports,
- 0:04a utility player is someone who can play multiple positions competently
- 0:08providing flexibility and adaptability. From my perspective,
- 0:12the routine I have you need may just be the utility player of
- 0:17classroom routines.
- 0:19Today we're talking with Kim Montague about I Have You Need and the ways it can
- 0:23be used to support everything from fact fluency to an understanding of algebraic
- 0:28properties. Welcome to the podcast, Kim.
- 0:33I am really excited to talk with you today.
- 0:36So let me do a little bit of grounding for listeners without prior knowledge,
- 0:40I'm wondering if you could briefly describe the I have you need routine,
- 0:45how does it work,
- 0:46and how would you describe the roles that the teacher and the student play?
- 0:50Thanks for having me, Mike. I'm excited to be here.
- 0:52I think it's an important routine.
- 0:54So for those people who have never heard of I Have You Need,
- 0:57it is a super simple routine that came
- 1:01from a desire that I had for students to become more fluent with
- 1:06partners of 1,000 thousand.
- 1:09And so it simply works as a call and response.
- 1:13Often I start with a context and I might say, Hey,
- 1:17we're going to pretend that we have 10 of something and if I have seven of them,
- 1:21how many would you need?
- 1:23So that together we have those 10 and so it's often prosed as a missing add-in
- 1:28with older students. Obviously I'm going to have some higher numbers,
- 1:32but it's very call and response. It's playful.
- 1:37I'll lob out a question, wait for students to respond.
- 1:41I'm choosing the numbers,
- 1:43so it's a teacher-driven purposeful number sequence,
- 1:47and then students figure out the missing number.
- 1:50I often will introduce a private signal so that kids have enough wait time to
- 1:55think about their answer and then I'll signal everyone to give their response.
- 2:01Okay, so there's a lot to unpack there. I cannot wait to do it.
- 2:05One of the questions I've been asking folks about routines this season is just
- 2:09at the broadest level, regardless of the numbers that the educator selects,
- 2:14how would you describe what you think I have you need is good for What's the
- 2:19routine good for?
- 2:20How can an educator think about its purpose or its value? You mentioned fluency.
- 2:25Maybe say a little bit more about that and if there's anything else that you
- 2:28think it's particularly good for.
- 2:31So I think one of the things that is really fantastic about I Heavy Need
- 2:36is that it's really simple. It's a simple to introduce,
- 2:39simple to facilitate routine,
- 2:43and it's great for so many different grade levels and so many different areas of
- 2:46content, and I think that's true for lots of routines.
- 2:49Teachers don't have time to reintroduce something brand new every single day.
- 2:53So when you find a routine that you can exchange pieces of content that's really
- 2:58helpful. It's short and it can be done anywhere and like I said,
- 3:02it builds fluency, which is a hot topic and something that's important.
- 3:05So I can build fluency with partners of 10,
- 3:09partners of a hundred partners of thousand partners of one can build
- 3:13complimentary numbers for angle measure and fractions.
- 3:17Lots of different areas depending on the grade that you're teaching and what
- 3:21you're trying to focus on.
- 3:23So one of the things that jumped out for me is the extent to which this can
- 3:27reveal structure when we're talking about fluency.
- 3:32In some ways that's code for the idea that a lot of our
- 3:36combinations we're having kids think about the structure of 10 or a hundred or a
- 3:40thousand or in the case of fractions one whole and its equivalence.
- 3:46Does that make sense?
- 3:48Yeah, absolutely.
- 3:49So we have a really cool place value system and I think that
- 3:53we give a lot of opportunities maybe to place label,
- 3:57but we don't give a lot of opportunities to experience the structure of number.
- 4:01And so there are some very nice structures within Partners of 10 that
- 4:06then repeat themselves in a way within partners of a hundred and partners of a
- 4:10thousand and partners of one, like I mentioned.
- 4:13And if kids really deeply understand the way numbers form and the way they are
- 4:17fitting together,
- 4:19we can make use of those ideas and those experiences within other
- 4:23things like addition, subtraction.
- 4:25So this routine is not simply about can you name a partner number,
- 4:29but it's laying foundation in a fun experience that kids then
- 4:34are gaining fluency that is going to be applied to other work that they're
- 4:38doing.
- 4:39I love that and I think it's a great segue. My next question was going to be,
- 4:44could we talk a little bit about different sequences that you might use at
- 4:49different grade levels?
- 4:50Sure. So younger students, especially in first grade,
- 4:55we're making a lot of use out of partners of 10 and working on owning those
- 4:59relationships.
- 5:00But then once students understand partners of 10 or when they're messing with
- 5:05partners of 10,
- 5:06the teacher can help make connections moving from partners of 10 to partners of
- 5:11a hundred or partners of 20. So if you know that nine plus one is 10,
- 5:16then there's some work to be done to help students understand that nine tens and
- 5:20one 10 makes 10 tens or a hundred.
- 5:24You can also use Capitalize on the idea of nine and one makes 10
- 5:29to understand that within 20 there are two tens.
- 5:32And so if you say nine and I say one, and then you say 19,
- 5:37and I say one that work can help sharpen the idea that there's a 10
- 5:41within 20 and there's some tens within 30. So when we
- 5:46do partners of 10, it's a foundation,
- 5:49but we've got to be looking for opportunities to connect it to other
- 5:53relationships.
- 5:55I think that one of the things that's so great I have you need is that we keep
- 5:59it game-like, but there's so many extensions,
- 6:01so many different directions that you can go and we want teachers to
- 6:04purposefully record and draw out these relationships with their students.
- 6:09There's a bit to it where it's a call and response oral,
- 6:11but I think as we'll talk about further,
- 6:13there's a lot of nuance to number choice and there's a lot of nuance and when to
- 6:18record to help capitalize on those relationships.
- 6:21So I think the next best thing we could do is listen to a clip.
- 6:26I've got a clip of you working with a student and I'm wondering if you could set
- 6:30the stage for what we're about to hear.
- 6:33Yeah,
- 6:33one of my very favorite things to do is to sit down with students and interview
- 6:38and kind of poke around in their head a little bit to find out where they
- 6:42currently are with the things that they're working on and where they can sharpen
- 6:47some content and where to take them next.
- 6:50So this is me sitting down with a student,
- 6:53Lanaya who I didn't know very well, but I thought,
- 6:56let me start off by playing I have you need with you,
- 6:58because that gives me a lot of insight into your number development.
- 7:03So this is me sitting down with her and saying,
- 7:05let's just play this game that I'd like to introduce to you.
- 7:09Oh, can I do one more thing with you? Can I play a game that I love? Okay,
- 7:13one more game. It's called I have you need.
- 7:16And so it's a pretty simple game actually.
- 7:19It just helps me think about or hear what kids are thinking.
- 7:22So it just is simply if I say a number,
- 7:25you tell me how much more to get to a hundred.
- 7:29So if I have 50, you would say you need,
- 7:33so that together we would have a hundred. What if I said 92 8?
- 7:38What if I said.
- 7:3975,
- 7:4425?
- 7:45How do you know that one? Because it's 30 to 70,
- 7:49so I just like my five more.
- 7:52Oh, cool. What if I said.
- 7:5464
- 7:5936?
- 8:01What if I said
- 8:0227
- 8:072
- 8:077
- 8:078?
- 8:09No, 72.
- 8:15No, 73.
- 8:16I don't remember what I said. Did I say.
- 8:1927 I.
- 8:1927? So then you said 73, is that what you said?
- 8:24And you were about to say 80 something. Why were you going to say 80 something?
- 8:27Because 20 is like 80 likes the other half,
- 8:32but I just had to take away more.
- 8:35Perfect. Let's see, three more. What if I said
- 8:3832
- 8:4368?
- 8:45What if I said 68, 32? What if I said.
- 8:4979
- 8:5421?
- 8:56How do you know that one?
- 8:58Because wait, wait, what was that one?
- 9:03What if I said 79? 79?
- 9:05Because 70 plus 30 is a
- 9:10hundred,
- 9:11but then I have to take away nine more because the other half is one,
- 9:16so yeah.
- 9:18Oh, you want to do it a little harder? Are you willing? Maybe I'll ask you that.
- 9:23Are you willing?
- 9:24Sure.
- 9:25Okay. What if I said now our total is a thousand.
- 9:29What if I said.
- 9:30850,
- 9:352
- 9:3550?
- 9:36How do you know? Or actually that'd be 150. How do know?
- 9:41Because
- 9:47800 plus 200 is
- 9:53a thousand, and
- 9:57so I would just have to take what was the number again? Eight 50?
- 10:03I would have to add 50 or have to minus 50 to that
- 10:08number. Perfect.
- 10:10640,
- 10:15360.
- 10:20What about 545?
- 10:27400
- 10:32you said 549.
- 10:37545 I think is what I said.
- 10:43That'd be
- 10:45465.
- 10:49How do you know?
- 10:50Because
- 10:54I just took away the number of each one.
- 10:58So this is five to make 10, and then this is six to make 10,
- 11:03and then it's five again, I think, or no, it would be 4 65,
- 11:08right?
- 11:094 65.
- 11:11I don't.
- 11:12Not sure about that one. There's a lot of fives in there.
- 11:14What if I give you another one? What if I said
- 11:18721?
- 11:22That'd be.
- 11:23If it helps to write it down so you can see it. Go ahead.
- 11:26389
- 11:31I.
- 11:31Think. Ah, okay.
- 11:35Because making a 10 in the hundreds and a 10 in the middle and a 10 at the end.
- 11:40Yeah. Interesting.
- 11:42Wow. So there is a lot to unpack in that clip.
- 11:47There is, yeah.
- 11:49I want to ask you to pull the curtain back on this a little bit.
- 11:52Let's start with this question.
- 11:54As you were thinking about the sequence of numbers,
- 11:57what was going through your mind as the person who's facilitating?
- 12:02Yeah, so as I said, I don't really know lanaya much at this point,
- 12:06so I'm kind of guessing in the beginning,
- 12:08and I just want her comfortable with her routine and I'm going to give her maybe
- 12:12what I think might be a simple entry. So I asked 50 and then I asked 92,
- 12:17excuse me, a chance to see kind of where she is.
- 12:19Is she comfortable with those size of numbers?
- 12:22You'll notice that I did 50 and 92 and then I did 75, 75.
- 12:26Often if I might hear a student talk about quarters with 75 and she didn't,
- 12:30but I did ask her strategy and throughout she uses the same
- 12:35strategy, which is interesting,
- 12:37but I changed the number choices up and you'll see if you were to write down the
- 12:41numbers that I did kind of backed away from the higher numbers,
- 12:45I went to 64 and then 27 and then 32. So getting further and
- 12:49further away from the target number.
- 12:52If I have students who are counting a lot,
- 12:55then it becomes cumbersome for them to count and they might be nudged away from
- 13:00accounting strategy into something a little bit more sophisticated.
- 13:03At one point I asked her 32, and then I asked her the turnaround of that 68,
- 13:08just checking to see what she knows about the commutative property.
- 13:12Eventually I moved into a thousand and I mentioned earlier that young students,
- 13:16you start with 10 and maybe combinations of a hundred multiples of 10,
- 13:20but I didn't mention that with older grades we might do hundreds by one or
- 13:25thousands by multiples of a hundred and then by fives.
- 13:29So I did that with Lanai.
- 13:30She seemed to feel very comfortable with the two digit numbers, and I thought,
- 13:33well, let's take it to the thousands, but if you notice,
- 13:37I did 850, 640,
- 13:41some multiples of 10 still. She seemed comfortable with those,
- 13:44but is still using the strategy of let me go a little bit over,
- 13:49let me add all the hundreds I need and then make adjustments.
- 13:53And so then I decided to do 545 and see what happened in that moment
- 13:58because at that point she's having to readjust more than one digit,
- 14:03And when I said the number 545, I thought, oh man,
- 14:06this is a poor choice because there's a lot of fives and fours.
- 14:10And so when she kind of maybe fumbled a little bit, I thought,
- 14:13is this because I did a poor number choice and there are lots of fours and
- 14:16fives,
- 14:17or is it because she's using a particular strategy that is a little more
- 14:21cumbersome? So I gave her a final problem of 7 21, and again,
- 14:26that was a little bit more to adjust. So in that moment I thought, okay,
- 14:29I know where we need to work and I need to work with her on some different
- 14:34strategies that aren't always about making tens because as she gets
- 14:39larger numbers or she's getting numbers that are by ones that
- 14:43becomes less sophisticated, it becomes more cumbersome,
- 14:46it becomes more adjustment than you maybe are even able to hold.
- 14:50It's not holding it in your head.
- 14:52We could have been writing some things down and we did towards the end,
- 14:54but it's just a lot of adjustment to make and the strategies that she's using
- 14:59really aren't going to be ones that help later in addition or in
- 15:04subtraction.
- 15:05So it's just kind of playing with number and she's pretty strong with what she's
- 15:08working on, but there is some work to do there that I would want to do with her.
- 15:13It was fascinating because as I was attending to the choices you were making and
- 15:17what she was doing and the back and forth,
- 15:19I found myself thinking a bit about this notion of fluency,
- 15:22that part of it is the ability to be efficient,
- 15:25but also to be flexible at the same time.
- 15:28And I really connect that with what you said because she had a
- 15:32strategy that was working for her,
- 15:34but you also made a move to kind of say,
- 15:37let's see what happens if we give a set of numbers where that becomes more
- 15:41cumbersome and it kind of exposed, there's this space where, again, as you said,
- 15:46now I know where we need to work. So it's a bit like a formative assessment too.
- 15:50Yeah, yeah. Interviewing students, like I said, is my very favorite thing to do,
- 15:55and it's tough because we want kids to be successful, which is a great goal,
- 16:00but I think it's often unfortunate that we leave students with a
- 16:05strategy that we think, oh, that's great.
- 16:07They have a strategy and it works for them,
- 16:10but we aren't really thinking about the long game.
- 16:13We're not thinking about Will this thing that they're doing support their needs
- 16:18as the size of the numbers increase, as the type of the numbers change,
- 16:22and we want them to have choice, and again,
- 16:25I have you need is fantastic because within this game,
- 16:28this simple routine, you can share strategies.
- 16:32There's a handful of strategies that kids generally use,
- 16:36and in the routine in the game, we get to talk about those strategies.
- 16:40So we have a student who's using the kind of same strategy over and over and it
- 16:44stops working because it's less sophisticated, it's less efficient,
- 16:48it's more cumbersome. Then in the routine,
- 16:51we get to expose other strategies that they can try on and see what works for
- 16:55them based on the numbers that they're being given.
- 16:58You made me think about something that I'm not sure how you could even put my
- 17:01finger on why,
- 17:02but sometimes people are wonky about this notion that students should have a
- 17:05choice of their strategies. In some ways,
- 17:08it makes me think that what you're really suggesting is part of this work around
- 17:12flexibility is building options, right?
- 17:14You're not trapped in a strategy if suddenly the numbers don't
- 17:19make it something that's efficient. You have options,
- 17:23and I think that really jumps out when you think about what happened with Anaya,
- 17:27but just generally what you're trying to build when you're using this routine.
- 17:32Yeah, I mean we are big fans of building relationships,
- 17:37so that strategies are natural outcomes,
- 17:39and I think if you are new to numeracy or you didn't grow up playing with
- 17:44number,
- 17:45it can feel like I'm just going to offer multiple and
- 17:50kids have to own them all and now there's too many things and they don't know
- 17:54how to pick.
- 17:55But when we really focus on relationship in number,
- 17:59then we strengthen those relationships in a routine with I have you,
- 18:04I grew up messing with number and the strategies don't feel like a bunch of new
- 18:08things I have to memorize.
- 18:09I've strengthened partners of 10 and a hundred and thousand and I understand
- 18:13doubles,
- 18:14and I understand the fact that you can add a little too much and backup,
- 18:18and so those relationships just get used in the
- 18:23way that I solve problems and that's what we want for kids.
- 18:26I love that we've spent a fair amount of time talking about this connection
- 18:30between building fluency and helping kids see and make use of structure.
- 18:36I'm also really taken by some of the properties that jump out of this routine.
- 18:41They're not formal, meaning they come up organically,
- 18:44and I found myself thinking a lot about algebraic reasoning or setting kids up
- 18:49for algebra.
- 18:50Could you just talk a little bit about some of that part of the work?
- 18:54I think that when we want kids to own and use properties,
- 18:58one way to go about it is to say,
- 19:00today we're going to talk about the commutative property,
- 19:03and you define it and you verbalize it and you write it down.
- 19:07You might make a poster,
- 19:09but more organically is the opportunity to use it and then name it as it's
- 19:13occurring. So in the routine, if I say 68 and she says 32,
- 19:17and then I say 32 and she says 68,
- 19:20then we are absolutely using the idea of 68 plus something
- 19:25is a hundred, and then 32 plus something is a hundred.
- 19:30There is something natural about you just know it's the other
- 19:35add-in.
- 19:36And some of the other strategies that we develop through I have you need,
- 19:40it's about breaking apart numbers in such a way that they are.
- 19:45And so when that happens for students, then we can name it afterward and say,
- 19:50oh, that's just this thing,
- 19:52and whether we name the property to students or not,
- 19:56it's more important that they're using. And so we put it in a game,
- 19:59we put it in a form that we just say, oh,
- 20:02that's just where you're breaking apart numbers and finding friendly adds to go
- 20:05together.
- 20:06I think it's really more important that teachers really
- 20:11understand the strategies that work so that they invite students to participate
- 20:15in experiences where they're using them.
- 20:18Yeah, I mean,
- 20:19what hits me about that is there's something about making use of a relationship,
- 20:23fleshing it out through this process of I have you need,
- 20:27and then at the end coming back and saying, oh, we have a formal name for that.
- 20:31That's different than saying, here's the thing, here's the definition.
- 20:34Remember the definition, remember the name.
- 20:37It just works so much more smoothly and sensibly because I've been able to apply
- 20:42that relationship and it feels like it's inside of me.
- 20:45Now I have an understanding and now I've just attached a name to that thing that
- 20:49just feels really, really different.
- 20:52I mean, if we give students the right experiences,
- 20:55then they have those experiences to draw on,
- 20:58and I'm a big fan of saying that some kids just have more experiences than
- 21:03others and all kids can,
- 21:05but it's our job to provide the right experiences for students that they
- 21:10can use and that they can think back on and that they can connect to other
- 21:14experiences that they have.
- 21:16Using the relationships of number is so powerful,
- 21:20and I think we just need to do more and more so that kids are just stronger
- 21:25in the properties and stronger in connections and relationships,
- 21:28so that then when they go solve problems, they're using what they know.
- 21:33Nice. So something that I want to call out for listeners who again,
- 21:36this might be new for them, is there's really two parts to this routine.
- 21:40There's the call and response,
- 21:42whether it's with an individual student or whether it's with a whole class of
- 21:46students, and then there's what happens after that call and response.
- 21:51So how do you think about the choices a teacher has after
- 21:56they've called a number and kids have responded?
- 21:59What are some of the choices of available to a teacher in that moment?
- 22:03Well, I think if you're playing,
- 22:04then you are kind of on a mission to learn more about
- 22:08students. For me,
- 22:10I'm always trying to figure out where students are and what they know and what
- 22:13they're tinkering with right now so that then I can make informed choices about
- 22:18what to do next. So I might make choices that are about my entire class.
- 22:22I might make choices based on I'm watching particular students as we play
- 22:27to see where are they kind of dropping off,
- 22:30where if I'm watching a video of myself playing this routine with a class,
- 22:34I'm scanning to say,
- 22:36those students wait a little bit longer and I want to strengthen some work when
- 22:41we do multiples of five because they're chiming in just a little bit late.
- 22:45So I'm looking for who's fluent, who's not,
- 22:48who's counting on by ones who needs another nudge. I'm ready to bump
- 22:52them a little bit further along. It's not about speed.
- 22:56This isn't a speed routine. I absolutely think we give kids some time to wait,
- 23:01but just enough. So like I said, we introduce a private signal,
- 23:04then they let me know when the majority of class is ready.
- 23:07Then I call for everyone to reply.
- 23:09But there is some bit of this where if you're counting by ones
- 23:14to get up from 68 to a hundred, then there's some intervention.
- 23:18There's some work that we can do to strengthen you.
- 23:21So it's important to give think time. It's important to use the private signal,
- 23:24and it's about the teacher being responsive to what they notice.
- 23:27Am I pulling a small group to give some students more experience,
- 23:30making connections? Am I moving some students to another set of numbers?
- 23:35Am I purposefully pairing students to give them what they need while I'm working
- 23:39with somebody else?
- 23:39So it's an information finding routine if I'm noticing and
- 23:44I'm aware of what's going on.
- 23:47I noticed with Lanaya, there were points where you called,
- 23:50she responded and you went right in and you called after and she responded,
- 23:55and there were other points where you decided to say something equivalent to
- 24:00tell me.
- 24:00How do you think about the points where you just keep on rolling
- 24:05or you pause and you ask that probing question?
- 24:09That's a great question.
- 24:11So when I make a shift is often a time that I will ask, how do you know?
- 24:16First of all,
- 24:17it's super important to ask how do you know when students have both right and
- 24:21wrong answers? We have a lot of kids who are only asked,
- 24:24how do you know when it's wrong?
- 24:25And then they backpedal and then they just pick a new answer.
- 24:29And I think giving kids confidence to commit to their answer and say, yeah,
- 24:34I know it's that, and here's how I know we continue to build that in students,
- 24:39that we are not the ones who hold all the answers when we question.
- 24:43And so in a shift is often when I think about making a change.
- 24:47So if I'm asking about combinations of 10 and then I shift to a five,
- 24:52multiples of five,
- 24:53maybe the first or second time I ask them how they know. I think about have kids
- 24:58had a chance to verbalize their thinking?
- 25:00There are moments where you completely understand what Len I is saying.
- 25:05And then there's a few where maybe if you're not a careful listener of students,
- 25:09you might think, I'm not sure she knows what she's saying, but over time,
- 25:14when you're a practice listener of students,
- 25:17even though their words may not be fantastic,
- 25:19they're kind of sharing their thinking.
- 25:21And so it will bog it down to ask how do you know every single time?
- 25:25But in those shifts where I want to know, are you changing your strategy up?
- 25:29Are you continuing to do the same thing every time?
- 25:32I think it's important to ask.
- 25:34So I have one last practitioner question before we move on from this.
- 25:39I'm wondering about annotation and the extent to which it's important and
- 25:43whether there are different points in time where it is, where it's not.
- 25:46How do you think about that?
- 25:48Yeah, I think that's a really important question.
- 25:50You can very easily hear something like this interview with Lanaya and think,
- 25:55oh, I'm just calling response, which there can be moments of that,
- 25:59but an important piece is annotation to draw out
- 26:04strategies that kids are using.
- 26:05So I might introduce this routine to a class and I might call in response a day
- 26:10or two or a couple of times depending on how many times that week or how often
- 26:14we get to play. But at some moment there's a chance to say, hang on a second.
- 26:19How did you think about that?
- 26:21If I say 65 and some kids call it back, I'll say,
- 26:26how did you come up with that?
- 26:27And then I ask students to share their strategies, and this is the sharing part.
- 26:31This is the part where students get to learn from each other. And so a kid might
- 26:35say,
- 26:36I added five to get to 70 and then I added 30 more to get to a hundred,
- 26:41and some kid will listen and I'm going to record that in a number line making
- 26:44the jumps that they say out loud. And another student might say, wait a second,
- 26:49that's not what I did. And so there's this opportunity to share strategy,
- 26:53and then we can say, well try that on,
- 26:55but if I'm not representing what students are saying on a number line,
- 26:59it could be really hard for others to hold onto it.
- 27:02It's not about hold everything in your head.
- 27:04So I often record on a number line as we're starting to share strategies
- 27:09or if I want to uncover a mistake that somebody makes,
- 27:13or if I see the kids all using one strategy,
- 27:17I want to draw attention back. Another really important thing
- 27:22is that I might want to lighten the mental load by recording the number
- 27:27that I said.
- 27:28If I'm saying 721 and I'm not writing anything down,
- 27:33you might be trying to hold 7,
- 27:352 1 or 720 and one at the same time that you're trying to do some
- 27:39figuring. And it's not about who can hold more. So depending on the age,
- 27:43the size of the numbers,
- 27:44I might just quick sketch the number that I said because they can stare at the
- 27:48number while they're also doing some figuring.
- 27:50Or they might write the number down on their notebooks so that they can do some
- 27:53figuring.
- 27:55One of the things that jumped out is the fact that you talked about when you
- 27:58stop to annotate,
- 27:59one of the ways that you do it is to annotate on a number line as opposed
- 28:04to, I think what I had in my mind initially is a set of equations,
- 28:07which is not to say that you couldn't do that,
- 28:09but I thought it was interesting that you said, actually,
- 28:11I will go to a number line for my annotations.
- 28:15So I think thinking visible is hugely helpful.
- 28:18And if a student says, let's say I give the number 89,
- 28:22if somebody says, well,
- 28:24I thought about adding one to get to 90 and then I added 10 more
- 28:29to get to a hundred,
- 28:30then their strategy of adding one more to get to that next friendly number is
- 28:35one of the major strategies that we would want to develop in students when
- 28:39they're adding. But another student might say, oh, that's interesting.
- 28:42I started at 89 and I added ten first to get to 99,
- 28:47and then I added the one.
- 28:48And that's a different major strategy that we want to develop.
- 28:52And when you put them both up on a number line,
- 28:55you can see that that missing add-in that missing part is 11,
- 28:59but they're handling it in two different ways.
- 29:01And so it's a beautiful representation of thinking of things in different
- 29:06ways,
- 29:06but that they're equivalent and that you can talk about it when you see it on
- 29:10the board. Equations are fantastic ways to represent,
- 29:14but I have an affinity for number lines to represent student thinking.
- 29:19Love it. As a fellow podcaster,
- 29:21you know that the challenge of hosting one of these is we have a short amount of
- 29:25time to talk about something that I suspect we could talk about for hours.
- 29:29Talk to folks who want to keep learning about I have You Need,
- 29:32and any other resources you would recommend for people thinking about their
- 29:36practice. Where could someone go if they wanted to continue this journey?
- 29:40They could listen to the Mathis Figureoutable podcast? First of all,
- 29:43we have had several episodes where we talk about this routine and revisit it
- 29:48over and over again because it's super powerful.
- 29:51We also have a free download that I think you're going to share.
- 29:55It's mathis figureoutable.com/you need,
- 29:58so you can see something that would be helpful.
- 30:02We have at Mathis Figureoutable an online coaching support called Journey where
- 30:07we just get to work with teachers on a regular basis to unpack the practices and
- 30:11the routines that you're using and spend a lot of time working with teachers and
- 30:15students in the classroom to develop these kinds of things that are more bang
- 30:19for your buck,
- 30:20to make the most that you can in the time that you have with your students.
- 30:24That's awesome. And yes, for listeners,
- 30:26we will include links to everything that Kim just mentioned.
- 30:30I wish that we could keep going. I think this is probably a good place to stop.
- 30:34Kim, thank you so much for joining us. It's been a pleasure.
- 30:38Oh, Mike, thank you. Appreciate you having me.
- 30:40Absolutely.
