This was such a good idea

Teachers: name your calculators.

Last year I put out a public beg for people to donate calculators to my classroom. I did that because keeping calculators in working condition and also literally keeping them is far, far more difficult than it ought to be. They’d get broken, the batteries would get stolen, the battery covers would get torn off and disappear, the screens scratched up, etcetera etcetera. 8th graders are savages. This is known.

I got a bunch of new calculators and spent the summer trying to figure out a way to keep them in working condition and in my classroom that was actually going to work for me.

Y’all.

At the beginning of the year I asked each of my five classes to nominate names for six calculators. You can see the names in the pictures. I vetoed a couple of their choices and instituted a rule that if a calculator was named after a person currently in one of my classes then that person had to give permission, but other than that those are all student-chosen names. There’s a decent variety to them; some of them are regular human names, a couple are named after celebrities, and some of them (“Tacotuesday,” “Caprisun”) are just kind of nonsense.

Y’see, now, if a calculator is missing, I don’t just have a missing calculator. Someone has kidnapped Stella. You didn’t steal the batteries out of a calculator! You killed Unc.

There are a ton of them that have their favorite calculator now and they refuse to use any others. Amazingly, I’ve never had to adjudicate any arguments over who gets what calculator. I was worried about that, but it’s never happened.

LaShawnda’s screen is scratched up. It happened before she (yes! “She”!) was LaShawnda. Someone brings LaShawnda to me at least once a week to report that her screen is scratched up. And we are on the sixty-first day of school and, until today, not one calculator had gone missing or been destroyed. You will note that LaJeff is technically LaJeff 2; that was due to a bad battery that corroded a terminal and can’t be blamed on a student– but again, once LaJeff stopped working I found out about it immediately. Last year someone would have thrown it away and then denied doing it.

The calculators get put back in the right places at the end of every class, without me needing to make an issue out of it. If one of them is missing, I say “Hey, who’s got Fredricson?” and Fredricson will be produced.

Hell, those names and numbers are written on with paint markers and none of them have even been scratched off. That’s stunning. That’s how careful they’re being with these calculators. Billy’s 5 isn’t really much of a 5 anymore but that’s it. Everything is still legible.

On that “until today” bit two paragraphs up: sadly, as of the end of the day today, Alex is missing. I have written “ALEX IS MISSING” in huge letters on my board and I would bet a hundred bucks that I’ll have Alex back by the end of the day, either because the kids will tear my room apart until they find him or whoever walked off with him by accident will bring him back. But even if I never see that particular calculator again, to only lose one in the first third of the school year is amazing. I’m going to name my calculators for the rest of my career. This is the best idea I’ve ever had.

So we’ve got a new curriculum for math this year, and like most curricula in 2025 there’s what was supposed to be a robust online component to it. My kids took a math test last week, and I discovered while they were taking the test that a question about exponents that asked them to show their work had not provided any way to put a number into a superscript.

Which, y’know, feels like it might be a massive fucking oversight.

We’re moving into the real number system this week and they’re starting off with terminating and repeating decimals, so a lot of moving back and forth between decimals and fractions. I spent an hour beating my head against their system and for the life of me I cannot figure out how to designate a repeating fraction. Is there a help system? Of course not. Check this out:

It seems like typing in an answer, highlighting the repeating decimals and then clicking that tiny button which I had to hunt for for twenty minutes (and remember, my kids are working on iPads, which make highlighting anything a huge pain) puts the repeating decimal line– which is called a “vinculum,” by the way– above the numbers you’ve highlighted.

Take a second and stare at the options in that text box and reflect upon the fact that this is supposed to be for 8th graders. I do not have the slightest idea what probably 90% of the icons on that thing are referring to, nor do I really have any idea what is supposed to be designated by an arrow pointing at three diagonal dots.

Unfortunately, it doesn’t work:

The top box is how it processed my entry. Why is there extra vinculum to the right of the seven? No idea, but it happened every time I tried. You’ll notice nothing extra is lined in the actual entry above. Why is the 27 in the bottom “correct” answer centered under the vinculum? Also no idea. I was not able to get a single answer correct involving a repeating decimal and absolutely nowhere was there any sort of help option that might have shown me what to do.

I sent an irate email to my team about how bullshit this was and I’m done for the night. I’m going to have these kids writing on the backs of shovels with coal by the end of the year. I’m so done with educational technology at this point that I can’t see straight.

Done-ish

The problem is that there are zombies at the end of the tunnel.

I have just completed my final exam notes for my 8th grade Math classes, which means that other than maybe creating some meaningless game-type worksheets– Sudokus and word finds and the like– I am done with any lesson planning for the 2024-25 school year. I’m certainly done with anything that matters. We’re doing final exam review through Wednesday, the final is Thursday. I’m going to do two hour long after-school sessions to do additional review for anyone who wants it on Tuesday and Wednesday. I expect them to be sparsely attended. The four days of school that remain are for nothing.

(Weird teacher pet peeve: occasionally people will hear things like that and say “Well, then they should make the year shorter, if you can be done early!” This would make sense except for the part where there would still be last days of the year. The point is that we have to get done before the kids go home, and there’s actually a ton of non-academic crap to happen at the end of the year!)

Anyway, I pretty much just have to get through the next four days without going to jail, which should be manageable. Should. We are probably going to have some students going to jail over the next few days, as the office has been pretty militant about the whole “start a fight and your ass is getting arrested” thing lately. But I should be able to manage. I hope.

In other news, I’m at the final boss for The First Berserker: Khazan, a game with a dumb name that I have put about 75 hours into over the last couple of months, and while I’ve enjoyed the game tremendously the thought of learning the moves for a three-phase final boss is proving to be so exhausting that I’m not sure I even want to do it. This game has been militant about the fact that there is never any way to cheese anything; you’re going to learn the bosses or you’re going to die. Most of the time the learning curve has actually been pretty fun, but three fucking health bars just feels like punishment and not fun. On the other hand, I can probably anticipate coming home wanting to blow off steam a lot in the next couple of weeks? I dunno, we’ll see. Maybe I’ll play something else and come back to it. There’s gotta be a fun game on the five to ten hours range out there somewhere, right? Anybody wanna recommend anything?

And here we go

I would typically expect to be Sundaying pretty hard at the end of Spring Break, but that’s not what’s happening. I’m not stressed at all. That said, I’ve had one hell of a time figuring out what the hell I’m going to do with my students this week, and more specifically what I’m going to do with them tomorrow, and I finally settled on a super basic, 20-question paper assignment with a mix of stuff from the last quarter on it. I’m titling the assignment “I Hope You Remember Math.” They’re all going to be lethargic and asleep tomorrow anyway so I think trying to start anything new (and the next unit is probability) is probably going to work against me. Then Tuesday through Friday on the basic principles of probability, skip the test, and two weeks of ILEARN review? Sure. Why not.

And after that … well, I chose the image up there for a reason. Right now I don’t even know what classroom I’m supposed to be in tomorrow (I was supposed to be back in my original room, but the weekly staff bulletin says otherwise, but the weekly staff bulletin also shows significant signs of having been copy-pasted from the last weekly staff bulletin) and that makes it really hard to plan. So tomorrow is going to have to be the last gimme day for a while, but that’s fine. It’s all fine. It’ll all be fine.

Unless the world blows up or something, but I’m gonna try not to worry about that too much.

Three down, one to go

I applied to teach summer school, did I mention that? I don’t know for sure that I want to do it, but I can’t decide that I do want it unless I apply now, and I have no real sense of how many jobs there are or what my chances are to get one, because for this type of thing they basically drop the teachers into a spreadsheet that sorts us by seniority and licensure and stuff like that and then spits out the teachers that get offered jobs. Plus I really only want to teach Algebra 1; I’m licensed for high school (there’s no middle school summer school this year) but I don’t want my first time teaching, say, Geometry to be in a three-week intensive summer course. Seems like a bad idea!

But yeah. I’d work four hours a day for three weeks and make a few grand (I’m paid at my hourly rate, which … I’m not 100% sure what my hourly rate is but it’d be decent money) and then I’d have all of July and the first week of August for my break, which doesn’t seem like it would be too terribly exhausting. We’ll see what happens.

At any rate, I’m done with three quarters of the 2024-25 school year, and I’m reaching the point where I’m having to admit that this has been a pretty good year so far. I’m pretty sure I’m failing fewer students this quarter than I ever have, or at least since returning to teaching after the furniture sales years, and that’s a good feeling. Then again, I had to fill this out for each of my classes, which is reliably the most annoying part of giving grades:

I know you can’t read that, but that’s a class of thirty or so students and I have had to rank each of them from zero to two on Persistence, Respectfulness, Initiative, Dependability, and Efficiency, and if you’re thinking that some of those sound like they might kinda be the same thing and you’re not entirely sure what some others mean, well, the kids never look at the numbers either so even putting enough energy into them to spread them out like I did is kind of a colossal waste of my time. This is more a measure of what kind of mood I’m in when I’m doing the grades than anything else, to be honest, and I wish the district would stop doing it. Annoying for teachers and irrelevant to students and parents is not a good combination, guys! Half of them don’t care about their actual grades, why would getting this shit matter? Plus every teacher ranks all of their kids– so I had to do this a hundred and eighty times– and so each kid gets thirty of these stupid little grades, which are just slapped into the margins next to the grade for each class in a way that is barely readable anyway.

Blech.

Today was the first day of spring– shut up, yes it was– and the way I know is that the entire building suddenly shifted to 100% playing grabass with each other all day. It’s supposed to be in the seventies tomorrow, and it’s Pi Day, which I don’t like, because there’s a building tradition that the math teachers bring pie, but I have a tradition where I pretend to forget to bring pie, while wearing the Pi shirt that doesn’t quite fit very well and I wear one day a year. And guess what? I’m gonna forget to bring pie again tomorrow! My wife and I almost stopped for pie on our way home from dinner but then we decided we were tired and I didn’t want to spend my hard-earned money on pie for however many Goddamn teachers we have in our building.

Also, I’m wearing shorts to work, because 74 or so outdoors for the first time all year will translate into approximately 190 degrees in my classroom, and that’s if they remember the heat’s not supposed to be on. I may burn to a crisp tomorrow, is what I’m saying, and that makes it even less likely that I’m going to be enjoying any pie.

I’ve completely lost it

I walked into my house after getting home from work with a good idea for a post in my head, did a couple of quick around-the-house tasks, and then promptly completely forgot what the hell I wanted to post about, and despite spending several hours since then trying to reconstruct my thought process, it’s completely gone.

So screw it, I’m going to complain about my job instead. Have you ever been asked your opinion on something and immediately realized from the way you were asked about your opinion that there was no way on God’s green earth that anyone was going to actually pay attention to what you thought? We had a teacher inservice day yesterday, and the math department’s big job in the morning was to go through a bunch of vendor kits for next year’s new textbook adoption. There were, I dunno, nine of them to go through? All of them with, bare minimum, 7th and 8th grade teacher editions and copies of whatever materials the students got, some with access to websites and digital tools and pacing guides and various and sundry other things that I won’t get into because they’re probably a touch too inside baseball for a non-teacher crowd. Many of them also included 6th grade materials and Algebra 1 as well.

Now, this is actually a pretty decent use of an inservice day, don’t get me wrong. There was no world where any of us were going to have time to do this on our own– remember, every math teacher in my building is on an overload right now because we’re so understaffed, so all of us teach for every second of the day except for our lunch breaks. (And I generally have a dozen students in my room during lunch, too, but that’s another story.)

Basically what we were doing was taking 20-30 minutes for each publisher, looking through the books and making notes. My notes were mostly bullet points. Some publishers were out immediately, sometimes for reasons having little to do with the actual quality of instruction– for example, one of them was not only organized in a way that made absolutely no sense to any of us and didn’t really seem to conform to Indiana standards, but had seven different thick consumable workbooks (250-300 pages each) for the kids, one for each major unit of study.

Now seven different workbooks is already impossible even before you get to the ridiculousness of the idea that you’d get through even one 300-page workbook in a single school year. I have about 175 students right now, total. 175 students times seven workbooks is 1225 workbooks. Each was, conservatively, an inch thick. That’s a hundred and two linear feet of workbooks.

Where the fuck am I supposed to keep all of that? Giving them to the kids is not an option. I will never see them again. Furthermore, since nothing is in the right order, we might be in Workbook 1 this week and then need Workbook 5 next week and Workbook 3 the week after that.

I don’t need a lot of notes for this one! It’s literally a physical impossibility. It’s a non-starter. The second I see seven workbooks per kid where everything is in an order that doesn’t match what the State of Indiana needs, I’m done.

You can imagine the shit fit that was thrown when our department head found out later that afternoon that we– as in each of us– were supposed to complete a seventy item rubric for, not each publisher, but each grade level for each publisher.

That’ll be the last animated .gif, I promise, but it felt appropriate. Not only were the rubrics huge, but they were Google forms, and they were written in eduspeak so ridiculously arcane that none of the three of us, nearly seventy years of teaching experience among us, could really parse what the hell some of the items were actually asking. And to do that for all grade levels for nine different publishers? Fuck you. Fuck you a lot. Two days of work, bare minimum. We had three hours, and by the time we saw the rubric the three hours were already over.

I don’t know if you’ve ever seen what a complicated Google form looks like when it spits out its results, but it’s a completely ridiculous spreadsheet. They’re terrible, and they’re user-unfriendly as hell. So to come back around to what I asked earlier in this post, it was immediately obvious that no one was ever going to attempt to look at what we were doing, because not only does no one have any time for that shit– remember the three teachers at our school are not the only ones being asked to complete this task– but it’s being generated in a way that makes pulling useful information out of it virtually impossible.

We all suspected the board was just going to order the cheapest curriculum anyway. So we sent in our notes and a tiered list of the ones we liked, the ones we were indifferent to, and the ones we actively didn’t like. If the people in charge want more than that they can find all of us subs for a couple of days.

I fully anticipate being told to find somewhere to put 1200 workbooks this fall.

On the final

On By Luther M. SilerIn TeachingLeave a comment

I have crunched the numbers, or at least calculated my pass rates, and of the 139 kids who took the 8th grade Math final, 55.4% of them managed to pass it. I curved the test to 20 points instead of 25 before putting it into the actual grade book, and with that adjustment, 66.2% of them managed to pass. This from a test that upon looking at it the first time, I was fairly certain that 2/3 of my students if not 3/4 of them would fail it.

(Only one student failed the Algebra final, before or after the modest two-point curve. I’m not worried about that class right now.)

Furthermore, and I’m not going to post the graphs here because they’re vaguely incomprehensible without the information that I’d have to strip out of them, my kids did pretty respectably compared to the other 8th grade Math teachers in the district. The data I get through the dashboard is incomplete but still a little more fine-grained than just pass/fail rates, but at worst we’re tied for the best performance in the district, at least of the teachers I can see data from, and depending on how you measure, you could make an argument for first or second. I’ll take “tied.”

A couple of other things: first, my 8th graders are unused to the concept of “final exam” or “midterm” to begin with. 7th graders did not have to take either last year. They are also, and I think this might be a place where my current grade policies might be hurting me, not used to the idea of a test they can’t retake in my room. I told them over and over again that they were only getting one shot at this and a bunch of them asked me if they could retake it anyway. I think I’ve managed to create some kids who just sort of breeze through tests the first time, knowing they can redo them if they have to, and if they don’t get a good enough grade the first time, they actually try on the second attempt.

Second, I may need to rethink the way I teach my classes from the ground up, so long as the guy who is in charge of writing these tests remains in charge of writing these tests. I am a big fan of Everyone Who Tries Can Pass, which, honestly, probably shouldn’t be true no matter how much I want it to be. He is a big fan of Rigor, which I generally find to be nothing more than artificial difficulty with no particular instructional utility.

To put this in simpler terms, if the objective is “prove you can multiply,” I’ll likely ask you what 7×8 is. His questions are more likely to be 7.13 x -18.014, that is if he’s not writing something utterly demonic like -7/18 x 8.12.(*) Both are “multiplication,” of course. Mine lacks Rigor. His lacks common sense. I feel like maybe if the kids are seeing a particular mathematical concept in 8th grade, maybe we ask them some simpler questions about that concept to see if they get the idea before we jump to the Rigor shit. Not so for my compatriot; the ILEARN is gonna be Rigorous, so our assessment must be as well.

This is the point where I generally throw my hands up and point out that if you want me to fail half of my students, please have the balls to actually say that. I’d ultimately rather have them feel like they have a chance to pass, and (slightly more importantly) a chance to understand the math I’m supposed to be teaching them. If every test question is high level and Rigorous, I can point at ten kids in every class who are already done before I pass the tests out, and that’s not including the ones who just don’t give a shit one way or another. That’s a whole different conversation, and one I might have sometime during break depending on whether I get around to analyzing my ILEARN data the way I want to.

So what did I do? Detailed guided notes. Detailed guided notes. Here, take a look at them if you want:

8th Grade Final NotesDownload

Basically every question in those notes is a test question on the final that has been slightly rewritten, basically just changing the numbers. In other words, if you paid fucking attention during the four days that we spent going over that nine page document, you had the entire test in front of you. And yes, the test was open notes. 45% of my kids failed with this document in front of them; most of them because they didn’t even glance at it during the test. (You may recall the test I gave a couple of years ago where I literally wrote the answers on the board and 23% of them failed. There is nothing I can do to get some of these kids to pass.)

Anyway. If you’ve read this far, go ahead and look through those notes, and keep in mind that I didn’t exactly keep that document a secret. I shared it with my boss and I gave it to my 8th grade partner teacher. I don’t think she used it with her class; I could be wrong.

You tell me: is this cheating? Meeting the kids where they are? Something else? I don’t know. They did a lot better than I thought they were going to do initially, and there are still a bunch of questions on that test (not all of them, to be clear) that I think are manifestly unfair for 8th graders. Looking at the kids who failed anyway, honestly, I’m not sure how many of them were possible for me to get short of taking the test for them.

The question is whether I just give up on those kids next semester and leave them behind so that I can have the rest of them ready for a test like this without this degree of a crutch, or if I keep providing the crutch. I genuinely don’t know. I really don’t.

(*) To get a little bit further into the weeds, converting decimals to fractions and vice versa isn’t in 8th grade standards, and I don’t have time to teach it. So there is zero chance that I’m going to give my kids a question where that must happen in order to get the right answer. Because it introduces a source of error that is not “do the kids understand this 8th grade standard” and I’m not about that life.

In which today was tomorrow

On By Luther M. SilerIn TeachingLeave a comment

I want to read tonight, so this isn’t going to be long, but I figured it was probably worth it to point out that today was a genuinely good day, for the most part, and the first day at least of the study guide seemed to go over pretty well. I have no doubt that as some routine sets in things will get a little rougher– four days in a row of taking notes, even in guided and somewhat abbreviated form, is gonna get on the kids’ nerves– but today at least went well, so I’ll take it.

Just discovered that the wind chill is supposed to be eight below tomorrow morning, too, so watch us get a two-hour delay on a day where I definitely do not have time for a two-hour delay and an actual cancellation would be a huge pain in my ass.

(There is no chance at all of a cancellation, but still.)

Anyway. Got a book to finish.
