Spiraling Math on a Stick

wp-1472180240601.jpg

I’m sitting on an airplane, about to embark on a nine day professional development bonanza in Baltimore, Maryland.  Right before we were given the airplane-mode directive I get this message from Christopher Danielson:

wp-1472179270639.png

Now, quick background:  I adore Christopher, everything he creates, his wife, his kids, and pretty much all that he touches.  I’m being hyperbolistic (which is totally a real word) but if you made a word cloud of my blog posts over the last year, it would be borderline embarrassing how large the words Christopher and Danielson would be.  S0, to make a long story a little bit longer, I was out-of-my-mind excited about this opportunity and wanted to text everyone I knew.   The hawk-like gaze of the flight attendant made that a difficult pursuit.  Anyway, it was a long flight.

Fast forward through a handful of prototypes, test runs with the resident 5-year old mathematician of the household, 250 colored card stock copies, and a pep-talk from the Professor himself, I was ready to hit the Minnesota State Fair to be the visiting mathematician/artist at Math on a Stick.

I settled on using 1-100 at the recommendation of Christopher because many children would be familiar with a hundreds chart either from home or school.  I could easily help kids made the transition from that familiar chart to this “different” way of arranging the same 100 numbers.  Making that comparison was something I would not have thought of, and it ended up being incredibly important.

Admittedly, I was a tad nervous that my idea would flop.  That all of the fun I’ve had with this spiral wouldn’t translate to a wider, younger, more playful audience.  All of that fear melted away when that first adorable young face sat down, and grabbed a marker.

Simply stated, this was one of the most fulfilling mathematics experiences I’ve had ever.  What Christopher Danielson has created with Math-on-a-Stick represents the paradigm shift in the way adults view mathematics through the playful exploration of children.

 

An Ode to Elementary Teachers

“The problem is that most of the middle school teachers don’t have a specialty in math.”

When I heard that statement, I knew it bothered me.  But at the time, I was unable to articulate exactly why.  There are a lot of problems with education, many more with math specifically.  But I know that pointing the finger squarely at the grades below is both unproductive and damaging.  Not only that, but when we are convince ourselves that groups of teachers lack certain “necessary” content knowledge, we close our minds to anything else they can teach us.

I’ve had a busy couple of weeks at AFT Thinking Mathematics training for 9 days and then straight on to Twitter Math Camp for another 5.  Both of those experiences will change my teaching for the better, and I found a common theme throughout:  Listen to what elementary and middle school teachers can teach you about mathematics pedagogy.

We talk about connecting representations of mathematics like graphs, tables, and equations.  But how often do we connect what kids do in elementary grades to what they experience in high school?  We lament in high school about kids lacking number sense, but how do our classroom routines support and build on the number sense kids have created through the primary grades?

Notice the similarities between the Ten Principles of Thinking Mathematics and the NCTM Math Teaching Practices:

I know those are dense, but they are the foundation of what we need to do in order to improve mathematics education.  Every shift we make needs to be based in these principles/practices.  And the ideas need to connect from counting to arithmetic to algebra to calculus and all the places in between.  We can no longer be complacent in teaching as we were taught.  Doing so means committing negligence toward a generation of students who need a deeper understanding of mathematics in order to use it successfully in the world they create.

Tracy Zager brought it all home for me with her keynote at Twitter Math Camp.  Here is her blog post with the link to the slides and the video.  I heard the same things the research had been telling me over and over in Baltimore:  We need to listen to each other.  There isn’t a hierarchy of teaching from elementary through post-secondary.  The conversations between vertical groups of teachers are important – even necessary – to helping our students develop as mathematicians.

Tough Cartoon Conversations

My sweet little angel came back from grandma and grandpa’s house proclaiming her love for Powerpuff girls. In the last 6 years I’ve watched my share of mind-numbing cartoons, most with female characters that make me want to shove a pencil in my eye and swirl it around in my brain.  Powerpuff girls has 3 female superheros, so I thought, what could be so bad?

In case you aren’t familiar, here is a classic depiction of the three little world-saving wonders:

Notice anything? …   I’ll give you a moment.

I try to run all of the media Maria is exposed to through the same scrutiny:  Does it include a diversity of characters, including diversity of race and family structure? How are the female characters depicted?  I’d like to say I’m looking for shows with a good message, but to be honest, I’m content with something that isn’t psychologically damaging at this point.

Hopefully you were as uncomfortable by the lack of diversity in the trio of pro-feminist ass-kickers as I was.  And if you don’t think that matters, consider this conversation I had with my daughter recently.

Me:  Maria, is it important to have all kinds of superheros?

M:  yes.

Me:  Boy superheros and girl superheros?

M:  Of course, mommy.

Me:  What about superheros with dark skin and superheros with light skin?

M:  No.  Superheros should only have light skin.

This stopped me in my tracks.  But I can’t fix it unless I’m willing to own my part in it.  I’ve worked very hard to make sure Maria is exposed to a variety of races, religions, sexual orientations, and family structures.  But the world the media has built for her is one in which superheros are white.  It’s my responsibility to disrupt this.   I’ve got much more work to do.

On Which I Pat Myself on the Back

0609161233_hdr-1.jpg

Warning:  Some of you are going to find this really dumb.  You’ve probably been doing this with your STEM-fueled 5th graders for years and are wondering why a 35 year old secondary math teacher is so excited about.  Four words: This. Isn’t, About. You.

So in April, I went with two great #MTBoS friends, Julie Wright and Danielle Reycer to the Exploratorium in San Francisco after NCTM.  To be honest, I was awed by the place, but my motion sickness unexpectedly overcame me, and I spent most of my time at the exhibits that didn’t require visual attention.  But in the back, there was a “maker-space” (or whatever you edu-folks call it) where they were making Scribbling Machines.  I took a look at it and thought “I want to do that this summer.  Maria will get a kick out of it.”

Step one:  get a 1.5 – 3.0 volt motor.  [Crap. Something with wires and electricity.  I can’t do wires and electricity.  Cuz I’m math, not science.

Tip:  Don’t purchase a new one.  Re-purpose one from a child’s toy.  [Sweet!  Look out, loud spinning, jump contraption from Hell’s fifth circle, I’m taking your motor!]

What I thought was the motor was not, but when I attached the battery, it became magnetic, which was neat.  I loosened about 8 more tiny screws and finally extracted the actual motor.  Now the game was on.  I was like a mad scientist, tongue to the side, laser focused on getting this scribble machine to function.  No, darling spouse, I won’t tell you what I’m doing, but you can see when I’m done.  Now go away.  

Here are a couple of videos of the Scribble Machine in action after a lot of adjusting and reconfiguring.  Yes, I know, I listen to great music:  Listen to the Music Radio on Google Play Music.

Here are the instructions if you are interested in making your own Scribble Machine.  Now if I could just get it to spiral…

You might be thinking, Ok, Beagle.  What’s the point?  You made a thing and now you want us to be excited for you?  Well, no.  Yes, I’m excited I repurposed a motor from Lucifer’s Leaping  Musical Spin Toy of Satan.  But confession:  I was one of those women who was convinced that robot, electrical, and computerized toys were designed with boys in mind.  These Lego robots weren’t exactly screaming my name:

But this girl looks genuinely excited, right?

Until I saw something I wanted to make, I was convinced I couldn’t.  My daughter is growing up in a country where for the first time a woman is running for president and a woman will adorn the $20 bill.  But what’s more important than those major accomplishments for me and my daughter is for her to see her mom try stuff and fail.  And try again, and fail again.  And then try one more time, and fail repeatedly until I have a working Scribble Machine that doesn’t do much but prove that I wanted to, so I did, tripping over myself along the way.  Maria wants to learn to ride a bike this summer.  And while I won’t be the one out there helping her, I want her to believe that she can and she will.

I see my own mother do this with her sewing.  I’ve seen her tinker and toil over stitches and fabrics and techniques until she creates something so unique, beautiful and truly one-of-a-kind. Like this (oops, stained) Doc McStuffin’s jacket:

Note:  Maria’s analysis of the Scribble Machine is still pending.  Will update with reactions and artwork.

 

Beagle Blockade

picplaypost_20160604_18_01_11.jpg

Last weekend we took the beagles to the dog park.  Although they are small, and somewhat unassuming, Herbie seems to be able to hold his own when it comes to keeping up with the bigger dogs.  Here’s a 15 second snippet of the adventure:

Needless to say, the beagles were thirsty by the end of the trail.  Of  course the park was equipped with water at dog level, but for some reason, Herbie refused to partake.  This little hound had just ran his tail off, howling all the way but would not drink any of the water overflowing the canine-sized bowl available to him.

You can bring a beagle to water, but you can't make him drink.

You can bring a beagle to water, but you can’t make him drink.

I made the joke on Facebook, “You can bring a beagle to water but you can’t make him drink.”  We use this phrase often as high school teachers (with “horses” obviously), but the sentiment is the same.  “I can’t teach a student who isn’t willing to learn.”  Now before we get defensive, I want to break this down a little.  I’m guilty as any of buying into this mantra at one time or another.

One of the best things to happen in my district is the adoption of a PLC model which requires that we not only reflect on how we teach but on what kids actually learned.  Simply bringing the horse (or beagle) to water is not sufficient (nor was it ever), but we now have a district-wide culture that supports students who reject the water the first time.  In my beagle example, Herbie was afraid of the giant yellow pump that was pouring water into the bowl.  When he got home, he was still thirsty and proceeded to slurp down the entire contents of his regular bowl on the floor in the kitchen.  I owe my dog another opportunity to drink water because, well, he’s a dog.  High school students, no matter how much we desire the contrary, are not adults.  They are children.  And sometimes they will reject learning the first time, and the second time (and sometimes repeatedly just to spite us).  But as educators, we owe them continuous opportunities for learning.

Well, it’s the first weekend of summer, and I’m coloring spirals and making beagle metaphors on my blog.  The next three months promise to be pretty fun.

Tales from the Nerdery

0524161408-1.jpg

I think math is neat.   I like to play with math.  And sometimes I come up with something that supports my theory that math is neat.

First, I took the numbers 1 – 100 and spiralled them around some regular graph paper.  I wondered what would happen if I colored in the multiples of 4.  I examined my work and thought, “Huh.  Well that’s neat.”

0517161529-1.jpg

Of course then I needed to spiral even more numbers and test out everything I could think of.  Multiples of 5, 6, 7 and so on.  Linear patterns, quadratic patterns, prime num…nope, nevermind.  I don’t do prime numbers.

Anyway, it’s that time of the school year where stress relief is necessary so I have been playing with these spirals for over a week. Today I came up with something worth sharing on my blog.  I took the positive y-values of y = x^2, y = x^2 + x, y = x^2 + 2x and so on, and colored those squares.  Then I put the images together and made a gif. Obviously, holding the camera at a steady angle is not a skill I have mastered.  But I still think it’s pretty darn neat.
