We had a nice little conversation today about a somewhat dark topic. As of yesterday, there were 21 confirmed cases of COVID-19 in MN. Today, the number was 35. When will it be 100?
The 12 yo: "Next Monday" (probably taking her cue from me, tbh)
Spouse: "Thursday morning"
Spouse's guess led to conversation about precision. We agreed on "when we learn that the number is ≥100"
Anyway, there's a lot of math wrapped up in this, and we are not in any way treating this topic lightly.
Lots of conversation about how this virus affects people in different circumstances; about what our responsibilities are to each other in the family, and to each other in society.
And also a little bit of mathematical modeling with very real consequences.

It's been a while, so here's a moment of recreational mathematics for you...
Here is one of my favorite specialty tiles from the deep triangleman archives.
That tile is a member of the family of spiraling pentagons and versatiles, and it does lots of fun stuff that they do, and also some other stuff that they do not.
A good deal of math's power lies in the problems to which it is applied.
What do we tell students about what math is good for when we select problems?
A journal article got me thinking about that this week. (Cover article in NCTM's MTLT, you can look it up, there's a paywall, you probably know someone who can find you a pdf)
I've had two contrasting experiences in cultural diversity and mathematics in the last 24 hours.
The first was yesterday afternoon, reading the cover story in the latest NCTM teacher journal "The Condo Problem".
That article critiques a textbooky problem that uses marriage as implicitly between a man and a woman, and describes the authors' journey in coming to understand the problem's problematic (as it were) nature.
Others around here may have read of his early math exploits. Critical thinking and all that.
I am happy to report that the occasion of his 16th finds him well of mind and body. Although with questionable taste in music (Africa by Toto is a current fave?!?!?!)
