January 2025 has been a long year, and I am way too tired for Sunday night right now, especially given that I was literally in bed by 8:00 last night and made it eleven hours before I even woke up to pee. I didn’t actually get out of bed until 9:30 or so, and other than taking the Christmas tree down, doing some reading– I am going to finish Wind & Truth tomorrow– and writing an assignment for tomorrow, I really haven’t done much. This image is prominent in tomorrow’s assignment:

This is going to be one of those annoying assignments that conceptually isn’t actually that difficult– you have two numbers in your coordinates, and you have to manipulate them in one of three ways to get your second set of coordinates, and those manipulations only involve making them their opposites or possibly putting them in reverse order– but it’s gonna break some brains anyway, because the sensible way to do this is to write down the coordinates of a point, look at the rule, then rewrite the new point, but my kids don’t want to write anything at all ever, and they’re going to try to remember the coordinates instead, and that’s … not gonna work.

Then I’m gonna get a chorus of “this is too hard!” and have to resist the urge to reply with “no, you’re just too lazy to do it right,” which is true, but … unhelpful. Also, if I’m tired, I’m gonna start making mistakes myself. So yay.

I hate teaching this unit. I don’t know if I’ve ever mentioned that or not? But I hate transformations. I really do. I think Pythagoras is next, and that’s a little bit more fun.

Maybe I’ll go to bed early again tonight.
