The last few weeks have been pretty profoundly discouraging on all three of my professional fronts. I'm sure it's just the ebb tide of education but it's worth mentioning that I'm specifically losing my mind over this WCYDWT thing, which is just a thing and may be much less than that, some form of digital wankery, I don't know.
It's like when you were a kid and you whispered the word "football" over and over again until the compound word separated and both parts seemed weird and meaningless all at once, that's something like giving three conference sessions on the same process of curriculum design in four months. I can't convince my fellow curriculum specialists at Google nor the teaching cohort I mentor online nor my high school colleagues of its value, which makes convincing myself of its value suddenly a real trick.
I'll say this much for certain: if there's value here it isn't in the comment, "Rates! We could talk about rates!" The response to these media too often breaks down into a checklist of mathematical conversation starters and if you're going to offer them any more than two minutes of class time then they absolutely have to be more than that. They have to earn their keep.
What do the students do with the photo? What questions will they ask? What measurements will they need? Once they've resolved the first question and feel like they have a stronger grip on the concept than they really do, how will you twist the scenario around to challenge them? How will you create that crisis?
Maybe it'd be better if I showed all of my cards up front, rather than this coy unveiling process which seems like a non-starter. If the exercise interests you, help me construct a narrative, an activity around these photos. Extra credit if you feel like contrasting it against Sean Sweeney's pass at the same material some months ago.
I only know I shot this because I felt like I needed it, because the alternative is a problem involving savings accounts with different principals and different monthly deposits and none of my kids have savings accounts.
