#MakeItReal Moment Number 16: The Funnies

The Funnies

When I was a kid I couldn’t wait for my Dad to come home from the convenience store with the Sunday Morning newspaper. He’d start pulling apart the sections, making a pile of news, sports, store flyers, and then, like a slow motion moment in a movie, he’d pull out…THE FUNNIES! I’m not sure where you’re from or what you called the newspaper comics, but in NJ we called them “the funnies” (insert future #MakeItReal Moment on regional dialect here). I can honestly say that I LOVED the funnies, although I can’t actually remember a time when I laughed out loud at one. Come to think of it, they’re not that funny. But they were a part of a grown up thing, the newspaper, that a child could covet as their very own. And they did approach situations from a different angle, often trying to make a twist ending by the third frame.  Those Sundays of my youth have stuck with me, so now I visit gocomics.com every morning before I read the news to check out two of my favorite comics, Foxtrot Classic and F Minus.

Here is today’s F Minus Comic.

 

See? Not “funny” per se, but this time it made me think about something totally different. I realized we could use comics (funnies) like this as catalyst pieces for teaching students about the Claim, Evidence, Reasoning structure. You see, this comic makes a claim. To many, a totally impossible and outlandish claim. But it’s not outlandish to me, or to my wife. A few years ago we were having a philosophical conversation about why multiplying 2×5 does not equal 12. Her thought was that it only equals 10 because we start with zero. How come the expression 2×5 doesn’t imply that we’ve started with a 2, then brought in 5 more 2s? After a while, we decided to call this method “Mathematatics” and will put it on Wikipedia soon to see if people believe in it (suckers). 

So look back at the F Minus comic. There’s a lot there, and plenty not there, too.

Claim: For a short time, 2 + 2 = 5.

Evidence: missing

Reasoning: missing

It’s time to put this in front of your students to see what they can do. Can they debunk the claim? Can they explain how this could be possible in the real world? Can they create a system like Mathematatics that could explain it instead, all the while citing their evidence (showing their work for math), then sharing their reasoning? I think they can. And I think it would be a lot of fun. 

Let me know if you use The Funnies in your class for Claim, Evidence, Reasoning lessons, or other ways!!!

#MakeItReal Moment Number 12

Measuring Priceless

So…this just happened.

 

I love incredible events like this, so when I saw a former math professor of mine post about it on facebook and noticed the first comment, I had to take action.

 

Instant Relevance is the idea of using what’s happening now, and what matters to you and your students, to engage in excellent opportunities to learn. I couldn’t pass this one up. So I took the straightforward route and went to my calculator and treated this like a simple interest investment. The formula for simple interest is I = PxRxT, or the Interest (earned amount) is equal to the Principal (starting amount) multiplied by the interest rate and the time. We know three out of those four things. What we have is this:

$450,312,500 = $59 x R x 58 years.

To start solving for the interest rate, divide the interest by both the $59 and the 58 years and you end up with 131,593.37, which is a ridiculously large number for a percent, and isn’t even really all that helpful yet. You see, in most of these problems, our answer comes out to be something like 0.05, which means the rate is 5%. So the ACTUAL interest rate needed to return this kind of investment is 100 times greater than what we got. In other words, 13,159,337% interest.

Image result for but wait there's more

 

I didn’t ask my math professor where he got the $59 from, so I checked. The painting sold for 45 Pounds in 1958, which, it turns out, converts to $59 in today’s money, but with inflation, is $125 in 1958 money. So, time to start over!!!

$450,312,500 = $125 x R x 58 years

For a mere adjustment to the low, low interest rate of just 6,211,207%. 

Follow Up Questions:

Is Mark, the facebook commenter, right? How could it be so different and seemingly so much more reasonable than what I got?

How long would it take if we knew we had an absolute cap of 10% compounded annually?

How could you use this event in Art, Science, ELA, Social Studies and other classes?

 

So my question to you is this: How will you use this extraordinary circumstance and likely once in a lifetime opportunity to quantify “Priceless” in your classroom, before it’s no longer relevant?

Stuck In My Own Perspective

In a recent Teach Like A Pirate chat (#TLAP) Dave Burgess and I responded to a question independently and identically, causing me to respond with this. Perspective is everything. I have a really cool niece named Anna who’s 13. She got the chance to fly with her dad (hereafter known as …

I See Math, People

Ever wonder if you’re the only one who sees things differently? After years of teaching math and looking for real world applications to help my students connect the math to life, I’ve realized that this is entirely backwards. We should be looking for the math in the real world around …

Teaching Math with Google Apps: A 4 in 1 Approach

One of the people I love talking to about teaching math is Alice Keeler (@alicekeeler), author of 50 Things You Can Do With Google Classroom. She’s almost excited as I am about the direction math instruction is going…almost. So naturally when we collaborate on math teaching ideas, not only do we …
