The Concrete-Representational-Abstract (CRA) strategy is the ideal way to teach math. It works by embracing how the brain naturally integrates information, utilizing multi-sensory engagement for deeper learning. When combined with Math-U-See’s unique sequence and mastery approach, CRA provides students with the essential tools for true understanding and long-term retention.

[00:00:00] Lisa Chimento: If you can introduce something concrete to a child, it’s easier for them to understand it. If they can see it, if they can touch it, if they can smell it, taste it, whatever, you’re giving their senses a chance to experience that thing.

[00:00:20] Gretchen Roe: Good afternoon, everyone. This is Gretchen Roe, and I am delighted to welcome you all to The Demme Learning Show today. We have a really special and an interesting conversation to have because this may be something that you just really haven’t thought about. My dear friend and colleague, Lisa, brought this to my attention several months ago. We really felt we needed a deliberative conversation about it so that we could frame for you why this is so important.
Although you will see it in the context of math today, I want you to understand that the principles we are going to talk about are omnipresent in much of our instruction, and we should be able to make the transition to recognize how important this is for so many kids. I’m going to let Lisa introduce herself, and then we’ll get to the crux of the conversation. Lisa?
[00:01:15] Lisa: My name is Lisa Chimento. I am a support and placement specialist here at Demme Learning for almost the past nine years now, full-time. My husband and I homeschooled our four children for 25 years. They’re all adults now and out of the house, and it’s a pleasure every day to work with families. This is an exciting conversation for me to have. I know it is for Gretchen as well, but actually, Gretchen, you’re the one who brought the CRA model to my attention a couple of years ago when I had the opportunity and the pleasure of sitting in on one of your talks at a convention.
I hadn’t heard of the CRA model before then, and then I did a little bit of digging in and researching on it. Then, a few months back, a customer actually contacted me and said, “I’m looking at Math-U-See, and my child has dyslexia, and her dyslexia tutor said we need to be using a math program that uses the CRA model. Does Math-U-See do so?” I was so excited to get that question. It really just spurred in my mind, “This is something that parents and teachers ought to know about.” I think it’s important. I think it can make an enormous difference in a child’s ability to learn and really understand math.
[00:02:37] Gretchen: I agree with you. When we developed the AIM program, which is behind your head and behind mine here, when we developed those programs, we were very intentional to use the CRA strategies, but we realized it’s also like throwing a rock in a pond. Steve Demme was prescient in the fact that the way in which he has structured Math-U-See leans so heavily into this. Sometimes you get too close to the forest to see the individual trees. I think we have reached the point where this is so much a part of our vernacular that it’s important for us to take a step back and help parents understand why this makes such a huge difference for kids. Lisa, where shall we begin?
[00:03:29] Lisa: Okay, so [chuckles] we get a lot of calls every day. Kids either just starting out or they’re along the way in their math instruction. They’ve been struggling, and parents aren’t really sure what to do. Many programs will focus on procedures. This is how you solve this kind of a math problem. Kids who have the ability to memorize that kind of procedure quickly will latch onto that. I know I did when I was in school.
I was all about the facts and the procedures and the rules and the formulas, but never really having understanding. That showed up in things like word problems because I didn’t know which operation to use, because I didn’t really know why I was doing what I was doing, or when I was supposed to employ a certain operation. If you told me which operation to use, boom, I could go there. It really indicated that I didn’t understand the math behind it.
It wasn’t until I started using Math-U-See with my own children that there were a lot of jaw-dropping moments of, “Oh, my gosh. That’s why we’re doing this. That’s why this works.” To be able to see that and understand it now, when you go to work a word problem or just use math in life, now you know what to do because you have that underlying comprehension of those concepts instead of just, “Oh, this is what I do because somebody told me I need to do it this way.”
This is what we wanted to do. We wanted to bring this idea about the CRA strategy. It’s a threefold strategy for introducing– Well, in this case, we’re talking about math. Like you said earlier, it can be employed in many other areas. The first of the three steps is concrete. I think most parents who have raised a child, even for a couple of years, know that if you can introduce something concrete to a child, it’s easier for them to understand it.
If they can see it, if they can touch it, if they can smell it, taste it, whatever, you’re giving their senses a chance to experience that thing. Then the second step is called representational. The concrete will involve in math, at least in Math-U-See. We’re dealing with manipulatives, physical manipulatives. The R stands for representational. Now, we’re taking those physical items, and we’re presenting drawings, illustrations, some sort of digital picture of it.
Then the A is abstract. That’s when we really get to the algorithm, the written equation or the mental math, all of that. We want to make that progression. We don’t just want to hit them with equations on a page because that’s procedural. It’s necessary, but it’s not going to build understanding. We want to build understanding. That’s the introduction to the CRA model. If nobody’s ever heard of it before, there you have it.
[00:06:34] Gretchen: Well, I also think it’s important to note that you can be a student who captures the procedural, as you have said. In the presence of stress, that will evaporate on you.
[00:06:48] Lisa: Oh, certainly.
[00:06:50] Gretchen: A lot of us who were only taught the procedural processes, when we encounter math in the wild, as my kids say, when math shows up in the wild, we panic because we can’t automatically access that archive of procedural processes.
[00:07:11] Lisa: Correct.
[00:07:12] Gretchen: We may be speaking to many members of our audience here who are, “You say you’re not good at math.” Maybe it’s not that you’re not good at math. It’s just that there’s a gap between your ability to recall the procedural process necessary for any particular function and the melding that is necessary to really fully understand that. For a lot of years, that was me.
It wasn’t until I found my way to Math-U-See seven years into my homeschool journey and eight math programs, eight different math programs, because I was trying different things for different kids, because I didn’t understand what was missing. Parents may see some of the things that are missing today in this conversational process. This actually has some science behind it. I wonder, Lisa, if you could explain because you’re the one who brought Jerome Bruner’s name to me. I think I had read his name all the way back when we were developing AIM. Then, of course, Teflon brain, it just disappeared out of my mind.
[00:08:26] Lisa: Jerome Bruner was a psychologist and an educational theorist. The work and the research that he did in coming up with the CRA model really shifted the focus from behaviorism to how people actually learn and think, and how they retain material information. This really helped him to better understand the mental processes that were involved in the way that humans learn. There is a woman named E.S.– I don’t know how to pronounce her last name.
[00:09:02] Gretchen: I asked the internet to tell me, and it’s Bouck.
[00:09:05] Lisa: Bouck. Okay, thank you. She did a lot of research to support that the CRA– and also she brought in what she called the VRA, so that when concrete manipulatives weren’t available, virtual manipulatives could serve as a replacement. Concrete is preferred if possible, but if not, then you could use the virtual manipulatives. Anyway, she supported that those frameworks are evidence-based practices for students.
Especially notable is the way that they have made such an enormous difference for children with learning differences, different learning challenges. We’ll get more into that. Let’s see. What we’re going to talk about here, this science of the way that the brain learns best and the way that the brain processes information, understands that information, and then retains that information in such a way so that when a person needs to retrieve it, needs to recall it, then it’s there for them. That’s what we found a lot of difficulty with.
Now, on the whole, you mentioned something just a minute ago about the thing that happens when we lose or forget the procedures. That happens often, especially if families are doing a typical school year and they take a summer off. We see this a lot when we get placement calls. Mid-summer, towards the end of the summer, people are getting ready to place their kids for the new school year, and they put a math assessment in front of a child who hasn’t done any math for weeks or months.
Well, math is a language. You’ve said this before. It’s the language of science. Like any language, if it’s not being used regularly, it’s easy to forget it. When kids have been heavily dependent on those procedures rather than understanding, and they haven’t done it in a while, it’s gone, and then you need somebody to remind you. I see this a lot when I see the way students work with fractions. They’re flipping fractions left and right and here and there because they’ve heard somewhere, they remember somewhere in the shadows of their memory that you’re supposed to flip a fraction for some reason.
They have no idea why or when or what it means, but they just take a chance, and they flip one of the fractions and then do something with it. That’s what we want to try to help move away from, because those procedures are necessary to solve equations. If you start with that, then that’s as far as it’s gone. We want to back this train up a bit and get going from a foundational point of view, and get started from there.
[00:11:59] Gretchen: When we say “concrete” here at Math-U-See, this is what we’re talking about. We’re talking about manipulatives. I have 2 + 4 = 6. I can hold these. I can touch them. I can touch the backs of them. I can touch the nubs on the front. It gives me tactile input for what I’m actually holding. The only reason that I make this digression is because last summer, when I did a presentation about math and anxiety, and I’m talking about the necessity of having a concrete representation, I had a mom who was so literal in the audience. She was seeing this as concrete as the stuff you pour for a foundation of a house.
[00:12:49] Lisa: [laughs]
[00:12:50] Gretchen: It is, in a way, because if you don’t understand that 2 + 4 = 6, then moving on, because of its very nature, because math is sequential and cumulative, if you miss the basics, it’s hard to build on that. Lisa, can you talk a little bit about the power of multisensory learning, what we have learned over the years here at Demme that tells us why it’s different? What makes this different from, say, just numbers on a page?
[00:13:29] Lisa: Yes, very different. I saw this from the moment we opened up our first level of Math-U-See with the integer block. At that time, the kit was very different, but there was this poster we opened up. There’s Decimal Street on the poster. What I realized was I had young children who were learning their numbers. We played with magnetic numbers on the refrigerator, and they could identify the numbers.
If you put the number two in the hundreds place, and then a number two in a tens place, and the number two in the ones place or the units place, you’ve got 222. It’s the same numeral in three different places. When they saw that Decimal Street and they saw the size of the blocks, the hundred blocks, the tens blocks, and the units blocks, all of a sudden, you realize there’s different values behind those numerals, depending on what place they’re falling in, in that number. That was, to me, the most brilliant thing.
I just couldn’t get over it. It just continues from there. A lot of times, we hear parents tell us, “Oh, my kids don’t want to use the blocks because those are baby things.” Well, I’ll tell you what, they’re not baby things. I’ve had quite a few engineer dads come to our booth at a convention and ask for a demonstration, and then sip with their mouth hanging open when they see the way that these concepts are taught, because we’re teaching algebraic concepts as early as the primer level, but all the way through into very formal algebra.
You’re teaching some very highly abstract concepts. When you present them concretely first, and the student can touch them, and they can see them, and you’re employing multiple senses, it makes such an enormous difference in their ability to understand. There’s something else that we do want to talk about. One of the folks that registered for the talk today asked a really great question about, “Can it make a difference for a child with dyslexia?”
I’m going to say it makes a difference for any child, but particularly for kids with learning challenges, and particularly for kids who tend to historically struggle with that ability to recall or retrieve information when they need to. The ability to work with something and engaging multiple senses allows that information to be stored in a part of their brain where they can retrieve it when they need it. That’s what’s making the difference here.
It’s not that dyslexic kids cannot retain information. Their difficulty is pulling it, calling upon it, is what I’ve often heard, or retrieving it when they need it. This allows that to be placed in a place where they can retrieve it. The brain is complex. I’m not a neurologist. I don’t understand it all, but I know that it works. We want to, as often as possible, employ not only in the instruction towards the children so that they’re receiving this receptively using multiple senses, but then they are also engaging with it expressively.
That’s a big part that we want to bring in here, because once I started to really dig into the CRA model, I started to realize, “We’ve got something really good going on here,” because the CRA model that we’re already employing, and then you add to that the mastery approach that Math-U-See uses, and something that I think just doesn’t get mentioned often enough, and that is Math-U-See’s unique sequence. You put those three together, and you’ve got this trifecta for success. That’s what we’re going to get a little more into here today, but I’ll let you direct this. [laughs]
[00:17:36] Gretchen: No, that’s okay. I appreciate the fact that you’re saying that. Before we move on, you had said to mention the quote that I gave you out of the book I was reading. I just finished a book called Open Ed. It’s a fascinating book about changing our attitudes about education. The reason this quote is relevant is because many of us who home-educated our children came to the table with this idea, and that idea is that the system doesn’t care about learning. It cares about processing. Now, I want you to sit with that for just a second, and then I’ll unpack this for you.
We have been taught as parents because our education was taught this way, that it is an accumulation of effort. There are things that we need to learn, and we measure that learning by taking a test. The challenge is if that’s the only measure of our learning, and I know I could probably ask anyone in our audience, or you, Lisa, “Have you ever taken a test, and then you didn’t recall what you did on the test a week later because you only retained the material for the length of that test?” What we’re trying to do here with a CRA model is give our brains the ability to house that information differently, not just about the retention for a period of time, but the retention long-term so that we can recall it as we have need of it.
[00:19:20] Lisa: There was a term used about– they called it a “memory anchor.” I think that was really a nice word picture for us because what we’re looking for isn’t something that a child can just know long enough to get the score we want them to get on a test. They’re going to grow up. They’re going to be adults. They’re going to live life. They’re going to use math in enormous ways in their lives that they can’t even predict.
Even if they don’t go into any kind of a field that uses higher-level math, they’re going to be using math everywhere in their lives, no matter what they’re doing. We want them to be able to do this with confidence and not be feel unequipped. We want them to be equipped, not just with the knowledge of how to solve a problem on a piece of paper and pass a test, but how to use math in their lives and be successful adults.
[00:20:13] Gretchen: Lisa, because this is so omnipresent in our minds as we work with Math-U-See on a daily basis, can you take a step back and explain to our audience and those who may watch this webinar at a later point in time, the elements and how they fit together, and why all of the pieces of the fit together of Build, Write, Say are so essential?
[00:20:41] Lisa: If anybody has used Math-U-See previously, you will be familiar with the term the Build, Write, Say method. That’s what Steve Demme calls what is being done in Math-U-See. To be honest, it’s being done in more ways than you can imagine. I remember when I was using the Gamma level for the first time, and the Gamma level focuses on multiplication. It blew my mind because he had the students building rectangles.
These are brand new. These are our new early learning blocks, and they’re big. They’re good for little hands. If you’ve got little ones and you want to start teaching some early math, very low-level math concepts. The idea that you could take a number, in this case, I’ve got a two block. They’re orange. I’m putting two of them together and making a rectangle. Now, of course, in this particular situation, it’s a square because a rectangle is a certain kind of square.
He said, if you are talking about multiplication, you are talking about fast adding of the same number. I’ve got a two, but I’ve got two twos. If I had a three, it would be three threes. If I had a four, it would be four fours, and so forth. It can be any number. What we’re looking at here, if I had two threes, I’ve got there. I’ve got two threes, and I can skip count by three, but I’m going to need to learn my multiplication facts.
The way that he does it is he has them build these rectangles and identify the dimensions. The over and the up. Those two dimensions are the same things as the two factors in a multiplication problem. You’ve got a rectangle that you’re finding the area. There are six square units. You can see square units. I remember going, “Oh, my gosh. Finding the area of a rectangle is the same thing as a multiplication problem.”
The ability to see this, to put this into a concrete application, you have a carpet in your house. How big is it? What’s the area of that carpet? You can go and measure the two dimensions and multiply them. You now know the area of that carpet or the wall standing next to you. The application for these things is practical, and it’s concrete. That’s the way this is used.
Now, the blocks are one piece of the Build, Write, Say method. We want them to build these rectangles physically, but don’t stop there. We also want them to write this equation. It’s going to be 3 x 2 = 6, and they’re going to speak it out loud. They’ve engaged tactile, visual, auditory, verbal, and writing. That’s five ways to engage with that one problem. I remember Steve saying, if he could have made them have a smell, he would because that’s an even more powerful sense.
What’s happening now is your brain is getting bombarded with the same piece of information through five different sensory channels, and it’s connecting those things in the brain. There’s links happening, and those links tell the brain, “Oh, this is important. I need to move this into long-term memory.” Then the more you do this, the more you are anchoring that in the memory.
[00:24:12] Gretchen: Often, we will have parents who’d say, “Well, I understand the Build, the Write, but I’m missing the Say.” Frequently, we have parents who’ll miss the Say with a young man because boys don’t like to say things out loud. Don’t make them do that. In the words of our colleague, Sue Wachter, that’s how the brain imprints the information into the right portion for later retrieval.
[00:24:43] Lisa: Correct.
[00:24:43] Gretchen: That verbalization is enormous.
[00:24:46] Lisa: That’s correct. I remember a mom contacting me, and they were using AIM to help her daughter, who was probably about 12 or 13, memorize her addition and subtraction facts and gain that automatic recall. She was fine with the Build and the Write, but felt very silly saying it out loud. Her mom said, “Any suggestions?” I said, “Let her know that this is not about just doing something and feeling silly about it. This is for your brain.” That’s all she did. She went back to her daughter and said, “This is for your brain.”
Her daughter went, “Okay,” and then started doing it. My goodness, what a difference it made. I just couldn’t believe it. It was all I had to say to her. I didn’t know what else to give her, but it worked. That’s what we need to recognize. This is not about putting your children through embarrassing steps. This is for the brain because this is how our brains retain information best and build better understanding as well. We’re going after two things there, not just to be able to remember it, but also to really understand what they’re doing so that they can take this math into life applications.
[00:25:54] Gretchen: Lisa, you talk often about the fact that mathematics instruction is a bottoms-up process. Can you explain that in a little bit more depth for our guests today?
[00:26:06] Lisa: We’ve talked about this many times in other webinars, but unlike other subjects, math is naturally sequential. It builds concepts on itself cumulatively. You can teach history and geography and English and lots of other subjects in any order you want, but when you don’t teach math in alignment with its natural sequence, gaps are created. It’s like you’re constructing a building, and you’ve left a crack in the foundation, or there’s a gap in the first or second or third floor, and you keep building and building and building.
You’re adding weight to an insecure structure. Eventually, it shows itself and, usually around Algebra 1, comes crashing down. We don’t want that to happen to children because it is exasperating when you have to do a math problem, or you’re learning a new math concept, and you don’t have the skills, the prerequisite skills, to be able to understand that new thing. There’s missing information or missing tools. You can even think of it that way.
What we want to make sure is that they’re getting the appropriate tools all along the way. When you look at math, you see sequence. It does not follow the typical sequence of a grade-based course where you might be teaching, “Oh, my goodness, hundreds of different concepts in a single school year.” Math-U-See does not work that way. Each lesson generally is one concept.
The mastery approach that Math-U-See uses allows for the student to take however much time they need to master it and to be able to teach it back to you before you move to the next lesson so that those gaps are prevented. We want them to be layering. I know, educationally, they call this “scaffolding,” I believe. They’re layering concepts one upon another so that they always feel equipped and confident to take on each new challenge.
[00:28:11] Gretchen: Lisa, this is often why you see families who raise their hands saying that math is not working for them, about the time they have kids that hit the division level. Can you give us a brief explanation of what that really means?
[00:28:23] Lisa: Yes, we see this a lot. When kids hit long division, they’re having to not only deal with a multi-step problem, but they are employing all of the stuff they’ve previously learned. They need to be able to add and subtract. They need to be able to multiply and divide. They have to follow all of these multiple-step procedures. They need to be able to put rounding and estimation to use. There’s all of this going on.
If there are any of those elements missing, what happens is every time they’re faced with a problem in division, they’re looking at this thing, and they have to stop. Now, they have to figure out, “I don’t know what this is.” For instance, if they don’t have their multiplication facts committed to long-term memory, they don’t have that automatic recall, they have to stop what they’re doing and skip count or sing a song or employ some kind of around-the-mountain strategy to get to their answer.
By the time they’ve gotten their answer to the multiplication fact, they’ve already spent a good deal of brain battery. Now, they come back to the problem, and they’ve completely lost their place. “Where was I? What did I do last? What do I do next?” They almost have to start all over again. Then the next digit, they’re faced with the same dilemma. The head comes off the page. The eyes go to the ceiling, and they’re digging around to get that fact, and then they have to do subtraction facts.
They have to do the same thing with the subtraction facts. So much interruption. Focus interruption, interruption of the procedure, all of it is they’ve lost it. What we want to make sure is those math facts are mastered before you get to long division. Before you do subtraction, have the kids learn their addition facts. Before they’re doing multiplication, make sure they can do addition and subtraction. Before they get to division, make sure that they know their multiplication facts like they know their name. If they don’t, call us, and we will show you the strategies on how to make that happen. When that happens, now, they’ve got all the pieces in place.
[00:30:39] Gretchen: I’m going to be the parent who calls and says, “But Lisa, my son understands how to multiply 6 x 7,” so how is that– He understands how to do it. He’s just not very quick at it.
[00:31:01] Lisa: What I say is ask him how he’s getting his answer. More often than not, they’re either skip-counting, or they’re singing a song or reciting a story, or however they learned their facts. Sometimes they’re using touch points, tally marks. I’ve seen all kinds of things. When I send out assessments, and I get the assessment back, and there’s all kinds of things going on on the outsides of the pages, tells me this child has not got that automatic recall of the facts.
It’s not a memorized fact. I know immediately, they’re being interrupted while they’re trying to work. That interruption means their brain is not free to focus on and remember the new material they’re learning. We want to make sure that all of those prerequisite skills are in order. It means that they’ve got the tools they need when they have to do the next thing. That’s why Math-U-See’s sequence is so different.
We’re not just pulling a whole bunch of stuff in every year that they have to learn because someone decided that a third-grader needs to know all of this. If they haven’t got those prerequisite skills, they’re not going to have what they say the third-grader needs anyway. Let’s not do that to them. Let’s make sure they’re learning their math skills in the same order that math naturally occurs.
[00:32:25] Gretchen: Now, Lisa, you and I actually participated in the preparation of a different recording in the last week or so. You said that both Alpha and Gamma have a narrower focus. I want you to elaborate on that a little bit, why that focus is narrow, and what that does for a student long-term. Because from the bleachers, you’ll hear parents say, “You mean you’re going to make us spend a whole year learning addition and subtraction, or you’re going to make us spend a whole year working on JOSS multiplication?”
[00:33:05] Lisa: Every Math-U-See level has a major focus, and then it also teaches associated skills. There are fewer associated skills taught in Alpha and Gamma levels because in those two levels, we’re also asking students to gain that automatic recall of the facts, memorize those facts, but not a rote memorization. I know some people bristle at the thought of memorizing because they feel like it’s rote memorization.
Well, rote memorization is just going to go out the door soon enough anyway. We want to make sure that it’s imprinted into long-term memory. There are strategies to do that. The Build, Write, Say is probably the most effective way that I’ve ever seen to do that because they are engaging so many senses. I know that parents will often feel impatient. “Why aren’t they learning all of these other things when our neighbor’s child, who’s in first or third grade, is learning all of these other things?”
Well, here’s the problem. Those kids are probably counting on their fingers because there isn’t enough time to give that child the chance to gain that long-term memory of those facts, because they’re onto the next thing, and the next thing, and the next thing. Math-U-See’s Alpha and Gamma levels give them more time. There’s more free space so that they can not only learn the why behind everything, but they’re also having time to memorize the facts.
In Alpha, we are using the blocks, as you demonstrated just a few minutes ago, and we’re building lines to show equal values. We’re employing that Build, Write, Say method. In Gamma, we’re building rectangles in the same way and identifying the dimensions, but using the Build, Write, Say method, and building bridges between concepts at the same time. One of the things that I think is so marvelous is that we are able to employ very low-level but concrete concepts of algebra in very young levels.
You just demonstrated. If we have a three and a two, and we want to build, write, and say what 3 + 2 is, so we’ve got a 2 and a 3. Oops, I’ve got this one backwards. There we go. Then they’re going to find the 5 block and recognize that the 5 block has the same value as 2 and 3 when they’re added together. They even make a groovy little equal sign. Well, at some point, we’re going to knock out one of those addends. It’s going to become what number + 3 = 5.
That’s algebra. It’s a very low-level algebra. By the time they get to algebra, they’re not going to get thrown by having alphabet letters in their math problems. [laughs] What this also does then is it builds a bridge between addition and subtraction so that they know now that when they have 5 – 3, what’s left over is 2. We are building bridges and making relationship connections between the different operations in math.
When they start learning multiplication, we start by skip-counting so that they are building a bridge between addition and multiplication. We don’t want to leave them on the bridge. We want to bring them over to fact mastery. Then we do the same thing in Gamma, where we are learning how to solve for an unknown factor. That’s going to lay the groundwork for division to follow.
Again, we’re making connections, relationships between the operations, and we’re doing it with concrete objects. I want to also say that although it’s not said so in the Build, Write, Say method, it is employed in our materials because the instruction manual also includes pictures of these blocks. We’ll talk about this as well, but it also means the fraction overlays when we get to epsilon, because we don’t use the blocks as often in epsilon. We use those fraction overlays.
Again, we’re building out the problem so that they can see it. It makes sense to them, and then the drawings of those very same objects are in the instruction manual. If you haven’t been using your instruction manual, use it. It’s going to add another layer, even if you’re just showing the drawings to your child. They’re working with the physical objects, but then let them also see them in flat two-dimensional drawings before you introduce the written problems.
[00:37:50] Gretchen: It’s the top of the hour, and we have just a couple of minutes left. What would be your closing thoughts for our conversation today?
[00:37:57] Lisa: First of all, if you want to do some research on the CRA model, go for it. It’s really, really interesting. Take a look at the way that Math-U-See stands apart. The way that it teaches math has been effective for children for 35-plus years now. I have four kids that went through it, and they don’t all learn the same way. I wasn’t dealing with some of the learning challenges that many parents are, but I have to tell you. I’ve got parents that are calling us, and they have children who have been diagnosed with dyslexia or dyscalculia, ADHD, working memory problems, Down syndrome, autism.
We have children with various learning challenges, and they are finding success in learning with Math-U-See because of the multisensory engagement, the mastery approach, and the unique sequence that Math-U-See uses. Like I said, I just think it’s a trifecta. I think it’s a formula for success. If you have any questions, please give us a call. We’re here. Amanda Capps and I are placement specialists. The rest of our customer service team are fabulous people who love, love, love to talk to homeschooling families and teachers and would love to help and answer any of your questions.
[00:39:25] Gretchen: Absolutely. Lisa, I want to thank you for taking the time for bringing my attention to the fact that we needed to have a more in-depth conversation about this. I think it was a really important conversation. Of course, I so appreciate the depth and breadth of preparation. If you all knew the depth and breadth and preparation that Lisa has brought to this experience, you would be humbled and proud for Lisa for all that she prepared in this process, because she really did do a great deal of digging into the why behind the process so that you would be able to understand it more thoroughly.
I want to thank you all for joining us today, for trusting us to come into your living room. It’s, as always, my very great pleasure to host the show. You can see why I love doing what I do. I have tremendous colleagues that I get to work alongside, and we get to help families like you. Thank you all today for joining us, and we’ll look forward to your coming alongside us again in the near future. Take care, everyone.

Show Notes
This episode details the Concrete-Representational-Abstract (CRA) Model, an evidence-based strategy designed to help students master math by bridging the gap between physical objects and abstract concepts.
The model consists of three stages:
- Concrete (working with manipulatives like the Math-U-See Integer Blocks)
- Representational (using drawings or pictorial models)
- Abstract (solving problems with only numbers and symbols)
Skipping the initial stages and focusing solely on problem-solving procedures can lead to gaps in real understanding, which is what we want to prevent in solid mathematics instruction.
Math-U-See integrates the CRA strategy through its multi-sensory instruction and unique sequence. The Build/Write/Say method is at the core of Math-U-See’s instruction, encouraging students to physically Build a concept with blocks, Write the corresponding equation, and Say the procedure to ensure deep understanding and long-term retention.
Crucially, the program follows a cumulative learning sequence, a “bottom-up” process that prioritizes mastery of one concept at a time before moving on, avoiding the rush of grade-level calendars.
Parental understanding of the essential nature of all three elements of the Build/Write/Say method and the mastery approach will create mathematical success for students of all ages and abilities.
