Show your work

Here’s another comment on that New York Times piece:

“mystery number game …. ‘I’m thinking of a mystery number, and when I multiply it by 2 and add 7, I get 29; what’s the mystery number?’ “

See, that’s what I mean, the ubiquitous Common Core approach to math teaching these days wouldn’t allow for either “games” or “mystery”: they would insist that your son provide a descriptive narrative of his thought process that explains how he got his answer, they would insist on him drawing some matrix or diagram to show who that process is represented pictorially.

And your son would be graded on his ability to provide this narrative and draw this diagram of his thought process, not on his ability to get the right answer (which in child prodigies and genius, by definition, is out of the ordinary, probably indescribable).

Actually, I do often ask CJ to talk out his process after we do a mystery number.  I share with the commenter the worry of slipping into a classroom regime where students are graded on their ability to recite the “correct” process.  But in general, I think asking about process is great.  For one thing, I learn a lot about how arithmetic facility develops in the mind.  I asked CJ the other night how many candies he could buy if each one cost 7 cents and he had a dollar.  He got the right answer, 14, not instantly but after a little thought.  I asked him how he got 14 and he said, “Three 7s is 21, and five 21s is a dollar and five cents, so 15 candies is a little too much, so it must be 14.”

How would you have done it?

Orioles 7, Brewers 6

CJ, AB and I spent Memorial Day at Miller Park, watching the Orioles outlast the Brewers 7-6 in an exciting 10-inning contest; it was Baltimore’s first visit to Milwaukee since 2008, which CJ and I also attended. Some details (CJ is helping me write this):

  • Lots of production from the bottom of the Brewers order, including back-to-back homers by Khris Davis and Lyle Overbay.  At that point Chris Tillman looked so overmatched that Kyle Lohse, in his last AB of the day, was apparently given permission to swing for the fences and hope for the best.  (He struck out.)
  • There’s nothing like watching AL pitchers try to bat.  Tillman made three tries at making contact on a bunt attempt, missed all three, and walked back to the dugout looking glum.
  • As an Oriole, Mark Reynolds was the worst third baseman I’ve ever seen, but somebody on Milwaukee’s staff has turned him around; he’s been notably good in both games we’ve seen this year, today making a diving stop and then firing a perfect throw to first from his knees.
  • Play of the game:  bottom of the ninth, Brewers with runners on second and third with one out, Reynolds up.  Ron Roenicke calls the “contact play” — pinch runner Elian Herrera takes off from third on contact, the idea being that he can probably score even on a soft groundout.  Unfortunately for Milwaukee, Reynolds hit a hard line shot directly to J.J. Hardy, who caught it and nonchalantly flipped to Manny Machado for the double play before Herrera even realized he wasn’t about to score the game-winning run.
  • Barbecue brisket sandwich from the Smokehouse unexpectedly good.  CJ ate four pieces of pizza.  Correction, CJ wishes me to say he “devoured” four pieces of pizza.  AB ate a hotdog.
  • Surprisingly high density of O’s fans in the seats behind the visiting dugout — I’d say 10-20%.
  • Former Brewer Hardy gets big cheers here when when announced.
  • I never get tired of watching Darren O’Day and his weirdo delivery.  He’s now been an extremely good pitcher for two full years and 2014 so far, and I don’t think people outside Baltimore have heard of him yet.

Here’s my Brewer-loving friend Laura Hemming, right before Roenicke called the contact play:

Sorry, Laura!

True love and baseball

Happy World Series Day, my favorite secular yontif!  In the spirit of the season I have a piece in Slate about CJ’s love for baseball, and mine.  I was extremely pleased that Rob Neyer liked it.

Here’s the finish:

I tried to make my son into an Orioles fan, like me. But the day at Miller Park he saw Carlos Gomez steal second, then third, then break for home, scoring on a wild pitch, like he was playing Atari baseball against a team of hapless 8-bit defenders, he became a Brewers fan for life. (To be precise, he describes himself as 70 percent Brewers, 30 percent Orioles.) We get along fine, in our mixed household. The inconsistency of our rooting interests doesn’t bother him. If there is a lesson baseball can offer us, it’s one about our deepest commitments; that they’re arbitrary, and contingent, but we’re no less committed to them for that. If I’d been born in New York, I might have been a Yankees fan, but luckily for me, I was born in Maryland, so I’m not. Jerry Seinfeld once remarked that baseball fandom, in the age of free agency, amounted to rooting for laundry. That’s not an insult to the game, as Seinfeld, a giant Mets fan, surely understood; it’s a testament to its deepest strength. My son’s love for the Brewers, like mine for the Orioles, is a love with no reason and no justification. True love, in other words.

Seriously, non-Wisconsin people, if you haven’t been paying attention to Carlos Gomez you are missing out on some joyous baseball.

Tweendom approaches

Spent 20 minutes today arguing with CJ over which is better, the Black Eyed Peas “I Gotta Feeling” or Carly Rae Jepsen’s “Good Time” (feat. Owl City.)  CJ favors Jepsen, arguing that songs are made of “music, singing, and words,” and that “I Gotta Feeling” wins on words but loses on music and singing.  His judgment of “I Gotta Feeling” as a piece of music is that “the music doesn’t match the singing and 3/4 of the music is copied and the 1/4 of the music that isn’t copied is boring.”

I asked CJ what “Good Time” is about and he said “it’s about people who overestimate their life and think bad things never happen in it.”

7 Apr 2013: Twins 4, Orioles 3

I took CJ to this game, his first at OPACY.  Great day out, perfect weather, but a terrible game, which both teams seemed to be trying their best to lose.  Joe Mauer dropped a foul popup.  Alexi Casilla made the last out for the Orioles on a weak grounder — but the pitcher bobbled it, and Casilla probably would have made first on the play if he hadn’t jogged half-heartedly out of the batter’s box.  And of course there was Adam Jones, who pulled up on a fly that was his to catch and let it drop three feet in front of him for a two-run double — yes, it was ruled a double, in an act of generosity so extravagant that the official scorer could have legally taken it off his taxes.  A week later, Jones would drop a fly ball against the Yankees to allow three runs to score in a 5-2 New York victory.  Jones looks like a really good center fielder, but the defensive metrics hate him, and I have to say the defensive metrics have the better of it at the moment.

Jason Hammel, in theory our ace, looked a lot worse than his line suggests; behind in the count all day, never seeming to find much of a rhythm.

So the Orioles, on the strength of this game, didn’t look like a good ballclub — but for the season as a whole, they’re holding their own against the powers of the AL East, and one can’t ask for much more than that.

After the game, CJ and I walked around the Inner Harbor, which has not changed at all since I was a kid, and seems to be just as crowded as popular and kid-pleasing as it ever has been.  OK, one change:  the Power Plant, which used to be a metal-oriented rock club, is now a Barnes and Noble.  Sort of strange, since metal is more popular and than it was when I was a kid, and books less so.  But Baltimore marches to its own beat.

Final note to self:  remember that, even in Baltimore, a crabcake is not the kind of food that’s likely to be good at the ballpark.

Singapore Math

CJ’s school is using it — this already comes as a surprise, since I have heard of it only in the context of “I hate my school’s discovery-based math curriculum and I’m supplementing with Singapore Math” and didn’t know it was actually used in schools.

The second surprise, given that context, is that Singapore Math is not brutally drill-oriented; in fact, I’d call it fairly balanced.  No flashcards, no pages with 100 problems all essentially the same.  Instead, when students are asked what 3×5 is, there’s a 3 x 5 rectangular array of stars drawn next to the problem so that the kid can see what the expression 3 x 5 actually means, not just what it evaluates to.  Similarly, kids are asked to color in 86 boxes in a 10×10 grid (the point being to learn that you can do this by filling in 8 whole columns and then 6 more.)  And with all this, there’s enough practice with basic arithmetic operations to build fluency and speed.  (Educational equity klaxon:  but of course I’ve already done a lot to teach CJ to be fluent and fast in arithmetic operations, because that’s what parents with cultural capital do.  (Subparenthetical: note that thanks to Peli Grietzer I now know the difference between cultural capital and social capital!))

Sometimes people criticize a curriculum for teaching students to do computations mindlessly, but I’m OK with that — mindlessness is a skill you need in life.  The right goal is to be able to do a computation either mindlessly or mindfully, as the situation demands.

Side question:  would Singapore Math have the cachet it does if it weren’t named for a country that’s both authoritarian and East Asian?  What if it were:

  • non-authoritarian, East Asian:  Korea Math?
  • non-East Asian, authoritarian:  Moscow Math?
  • non-East Asian, non-authoritarian:  Israel Math?

Let us now praise American Airlines

Did you ever wonder what would happen if your son left the carry-on suitcase he was pulling at the bottom of the jetway before getting on the plane, because that’s what we always do in Madison, but there wasn’t actually a gate-check tag on it?

It turns out that, at least if you do this in Tucson on American, and if you have a luggage tag with your name on it, they’ll cross-reference the name against their passenger record and correctly check the bag through to your final destination.

I go in bars

We walked by a softball game with a keg at Vilas Park today.  Tanya asked me if I thought CJ knew what a keg was.  I said, of course CJ knows what a keg is, he lives in Wisconsin.  Tanya said, but how would he know?  So we asked him, hey, CJ, what’s that big silver thing by the softball game?  And he said, “That’s a big beer thing.”  And I said, how do you know?  And he said, “I know what a tap looks like!  I go in bars!”
