Kid-focused #makered Integration
I struggle to find ways to integrate my #makered work with other 7/8 classes. If teachers have a prep period, it’s during our elective block. Also, when push comes to shove, I’m not sure the 3×45 minute #makered experience is actually #makered. Not to get all maker-tao on this, but it’s something I worry about.
Instead, this year I’ve taken advantage of the multi-year relationship I have with many of these kids, and have started to lob interesting things at them via email. As the curricular tech guy when they entered middle school, I’m very likely the first person from whom they received an “official school email.” Sometimes I’m sharing choice bits from my #makered links collection. Other times, it’s a particular problem or project that’s active in the space. Here’s one I sent today to a few of the more puzzle-minded 8th graders.
I made a mistake, and I could use your help.
This will sound like a math problem, but it’s not. I mean, it’s a problem, and I think that math’s probably my best hope to solve it in a way that doesn’t involve undoing and redoing hours of tedious work. That’s actualy, physical, with my hands work! Ugh.
But importantly, this isn’t a problem from the back of a book. This is something that emerged from a weird combination of design, technology, and cultural habits. Oh, and mistakes I made. Because I was in a hurry and didn’t check my work as I was going.
There’s pictures to go with this, but they may not show up “in line” in Gmail.
There’s a clock project in Makers. It’s pretty cool. It will show the hours by turning on individual lights at the end of the little arms.
These lights are arranged in a chain, or strip. This is useful for a bunch of reasons, but the most relevant is that you can turn any of them on/off by referring to it’s position in the strip.
There are 12 lights in the strip (because, you know, clock) but they’re numbered from 0 to 11 (because computers).
Here’s my mistake. Because I was looking at the back side of the clock while building it, I wired the lights so that the order of the strip went around backwards. Dumb move on my part, compounded by the fact that I didn’t catch it until I had wired a bunch of other stuff in place.
So now the numbered lights in the strip are arranged around the clock like this.
This is bad.
The program reads the hour part of time as a integer between 0 and 23. That’s 0<=hours<=23 for those keeping score with interval notation
Can we find a clever way to use math, to create a rule, that maps the integers [0,23] to the integers [0,11] so that the proper light is turned on?
