What were you trying to do? Listening in to kids think while they're creating something new

I talk to kids all the time in my math and making classrooms about what they are doing, the choices they're making and why. But for some strange reason it never occurred to me to record these conversations...until recently. Discovering a voice recorder on my iPhone has spurred me toward documentation in a big way.  Here are my first two recorded conversations, both around a Weaving Algorithms session I did with some 4th graders today:


4th grader: I’m trying to get to not do the same pattern twice.
Me: So not even the same color pattern? There’s like random colors across the top [the warp]...? And what did you do the weft [weaving across] part?
4th grader: I had one continuous pattern. I did yellow, orange, red, purple, blue because they were connected in the color wheel and then I did green, and the other shade of green and then the other blue…
Me: …and then you started again.
4th grader: …and I tried not to make the same weave pattern…I tried not to make that touch two other things from the same color but this touched like three yellows.

All I've got to say for this one is: It takes a LOT of thinking to create an intentionally random design or pattern. I'm impressed!

Here's a conversation about a weaving design on the completely opposite side of random:


Me: Can you tell me why you’ve got your calculator out?
4th grader: I was trying to figure out how many castle wall patterns…
Me: Can you tell me the numbers of the castle wall patterns?
4th grader: 26 which would probably be 13 on the bottom…
Me: Okay, the orange ones?
4th grader: 13 orange ones and 13 blue ones?
Me: And you call them castle wall patterns because…
4th grader: Because they kinda look like castle walls…
Me: Like the turrets. Okay, cool! Anything else?
4th grader: The pattern was over over, under under, over over, under under...
Me: So there was an orange and a blue that went over over and you took another orange and blue pair and went under under…nice!

I've got many new thoughts about how to use the voice recorder to help me talk and listen to kids. For now, though, it's very clear that in the noisy rush of large noisy classroom it is too easy for me to rush kids or inadvertently cut them off.

Here are a few other lovely designs from the day:

18 cubes + 6 colors + 1 elastic = Countless Hours of Math-y Fun!

We recently bought a What'zit*. A What'zit is officially a fidget toy. But, as my 9yo said, after playing around with it for a day: "It's a math toy, Mama. It's sort of like a Rubik's cube."

Here's what it looks like.  Actually, I'm calling this one Rectangle 0.


There are only 18 cubes but we have had a huge amount of fun working within these constraints! My first question was to see how many balanced/even designs I could make. I quickly noticed factors and multiples in every design.

Here's Rectangle 1:


Here's Rectangle 2:


My kid saw me making Rectangle 2. The next day she said, "Mama, I'm going to make a square like you did.  Oh, wait...this is harder than I thought [counting the cubes] 1, 2, 3, 4, 5...1, 2, 3, 4, 5, 6...[repeating the count just to make sure]. It's not a square. It's actually a rectangle."

The color patterns in this thing are fascinating too. For example, here's a 3x6 rectangle.


Here it is again. What's the difference?


The colors highlighted the number patterns. Above there are 3 sixes, grouped two different ways. These two pictures are of the same cube, but from different angles:

  

My kid spent a happy day experimenting with different configurations, like these:



We also made different kinds of zig zags:



And then did some double zig zags:


I love how she off set this!


FUN!


*Like any other product I talk about on this blog, I discovered this toy on my own am sharing our experience in the name of math fun and discovery. I never review products for compensation of any kind.

Pakora Math [#tmwyk]

My kid LOVES the vegetable pakora appetizer at a local Indian restaurant. Yesterday she had some serious dental work done and I sweetened the stressful day with an offer of pakoras for dinner.

Our plan was to get one serving of pakoras to eat there and one to take home to share with the papa. We talked on the way to the restaurant that we needed to find a way to split the two orders evenly between three people.

Our in-house plate of pakoras came first; there were eight of them.

"So," I said, "How many should we start with?"

9yo: Two for me and two for you.

[Eating commences. Yum!]



Me: So we have four left. What should we do now? If we take one more each, there'll be two left on the plate and...Oh wait, I just realized we don't know how many pakoras there will be in the take out box!

9yo: Probably eight.

Me: So how could we split 16 Pakoras evenly between three people?

9yo: [Turning slightly and looking to her left for a couple seconds] Five and one third.

Me: I wonder how you got that?

9yo: Well, 5 times 3 is 15 and then you split the last one into three pieces.

Me: But what if there are only 6 pakoras in the take out box? How will we split 14 pakoras so it will be fair for all three of us?

9yo: Well, 4 times 3 is 12...

Me: But that leaves two. How would you share those last two pakoras between three people?

9yo: Well you could cut them in half and each person gets a half.

Me: What would you do with the last half?

9yo: Give it to me? <sly grin>

Me: Well...but what could you do to share that last half fairly?

9yo: Hmmm. Cut it into thirds?

Me: Cut the last half into thirds? That would make what, exactly?

9yo: Um....really tiny pieces?

Me: It would make sixths!

[Take out order arrives!]

Me: Let's see how many are in this box! There are EIGHT!  Great, what do we do now? We've each had three, let's take two more each ... Okay, now Papa has his five in the box, and there is one left. Wanna cut it into thirds?

9yo: Sure! ... well they're not really equal ... I'll take the biggest piece!
............................

I love how we ended up talking about two ways to share between three people. First, many pieces into three shares. Second, only two pieces into much smaller shares. Both fractions, but of slightly different natures I think. In my mind "fractions" refer to really small pieces. But that's obviously not the case with my share of five whole pakoras!

During the entire conversation I felt really proud of myself! Helped by projects such as Talking Math with Your Kids and also a recent video showing two boys figuring out how to share sausages, the whole pakora conversation just flowed. Good modeling is definitely the key to learning how to 'talk' math.

And, as we were waiting for our check we also got a bonus #dswyk (Doing Science with Your Kids)!

Me: What do you think is happening there? 
9yo: There's a rainbow on my hand! Lol.

"Doing math means a lot of different things including..."

I LOVE this Ignite talk from Annie Fetter of The Math Forum.  Here's why:

"[My mom] didn't think of herself as someone who did math ... Why is it that intelligent people who are good at sense making and good at problem solving feel no affinity for school mathematics? If our students could do the things my mom could do we would be ecstatic. As math educators we need to make sure students and grown ups understand that doing math means a lot of different things including making incredible, beautiful art."

I especially love this because in her talk Annie points out all the math doing and making in which her mother engaged.



So...how would you fill in the blank here?  

Doing math means a lot of different things including...

Would love to hear your answers!

What is the role of embodied mathematics in our classrooms?

I have come to terms with the fact that different people see different things in Math in Your Feet depending on where they stand. Based on feedback from a wide variety of teachers I've had the honor of working with this summer, as well as my own perspective, here are some possible answers to the question:

What is Math in Your Feet, really? 
  • Low floor, high ceiling (useful and interesting to diverse groups of learners and backgrounds)
  • Geometry topics
  • An in depth inquiry into mathematical patterns including explorations of transformations, symmetries, group theory and equivalence classes.
  • An opportunity to use mathematical language in context. 
  • A chance to build and strengthen spatial reasoning, what I call "the step-child of mathematics education".
  • A chance to harness existing body knowledge (developed through being in the world) to strengthen understanding of mathematical practices and topics.
  • Potential for developing new insights about previously familiar mathematics.
  • Inspiration for mathematical question asking in fourth graders and (open-minded) research mathematicians alike.
  • A major cognitive schema. The Source-Path-Goal Schema, to be specific. ALL of it.
WAIT! What?!?

Yep. A schema is a cognitive framework, essentially a mental frame that helps us organize, sort and classify sensory input into something that makes sense to us. The book Where Mathematics Comes From by Lakoff and Nunez makes a comprehensive argument for how the core schemas identified in cognitive science also come to influence the development of mathematical ideas. Lakoff/Nunez call the source-path-goal schema "ubiquitous in all mathematics" meaning: this is how we need to think when we do mathematics at ANY LEVEL.

We build MiYF dance patterns by asking:"Where are we starting [source] , where are we going [goal], and how are we going to get there [path]?" 

During this process we use the following categorical variables to create our patterns which help us think about location (foot position) and the body's trajectory (direction), and how exactly we're going to get from point A to point B (movement)

The Source-Path-Goal Schema ("ubiquitous in all mathematics") includes the following:
[Direct quotes are presented in italics here and can be found on p37 of the book.]

A trajector that moves, like these guys:



A source location (the starting point):



A goal--that is, an intended destination of the trajector. In this case, both boys are turning left toward their intended destination facing the back of the dance space.



A route from the source to the goal. The route of girl on left is a left turn. The route of the girl on the right is a right turn.



The actual trajectory of motion. 
The position of the trajector at that time.
The actual final location of the trajector, which may or may not be the intended destination.


In the picture below, the girls have reached their intended position, the front right diagonal of the square:


We had a fantastic time with embodied mathematics at Twitter Math Camp 2014, but on top of being highly engaging it also brought up a really important question among the math educators involved:

What is the role of embodied mathematics in our classrooms?

As we move this question forward together we need to remember that all learners (even adults) need experiences with the processes of math in multiple modes and settings. With these kinds of experiences, including the body-based ones, math learners are well supported to engage in mathematical content in meaningful ways.

Ultimately, in the early years of creating Math in Your Feet I didn't explicitly set out to build the program around the source-path-goal schema but I asked honest questions about what math is and how it's learned. These are the kinds of questions that can put us in a good place to start uncovering the hidden metaphors carried in our bodies. From there it's not too hard to envision the path toward using these ideas in creating meaningful, useful body-based lessons for classroom use.

There's so much more to talk about in relation to this topic, but I'll stop here for now. We have our "source" question. We can see the "path" ahead as well as the "goal". Let's get started! Together.
