I'm no math teacher but I'd call that worth extra credit!

I mean, defining the cheat sheet limitation in such a way for Math students is really just asking for it ...
If the parameter is that it’s 1 sided then you don’t need to be this creative, just have a longer sheet
Yeah, but that would make them have two sides, one (or both) with writing on it.
I think the joke here is the one sided part. Paper sheet has two sides.
The shape student is using is called möbious strip and its pretty famous mathematical object for being shape with only one plane. Another one is Klein bottle and im sure there are other ones too.
How else are you going to have a 1-sided sheet?
Hmm. Would the surface of a sphere qualify as a sheet? But I feel that is cheating. The inside would count as another side if you could only get to it.
I would allow it, it's brilliant. The main learning benefit of cheat sheets comes from writing them, not from using them.
Depends on the class.
I had a statistics course that allowed us one single sided page, but as long as your printer could handle infinitely small print, she didn’t care if you had magnification. You could hypothetically have keychain bible print for your entire book as a cheat sheet, it just wouldn’t help you in the allotted time.
My cheat sheet for R was nothing but codes because I’m not a coder at all (R is my entire coding experience, and it was fucking miserable) and that helped if I remembered to label the fucking codes. And LOL nope.
But I cheated in other classes by doing such nonsense as writing vocab on my shoes… in college language courses, which I paid for myself.. so dumb and counter productive.
I was never smart enough to cheat in regular school.. I just brute forced the work.. ironyyyyyyyyy
A great teacher would surreptitiously plant the idea to do this.
This. Most classes in uni allowed us to have a limited number of cheat sheets and after writing them I rarely used them. Open book exams are a different beast though.
I take certification exams that are open book. I still create an index aka cheat sheet because typing it out makes me internalize what I’m reading. It’s also easier to refer to an index of a couple of pages vs several books in a time-bound exam.
One of my math professors would always ask if people wanted an open book take home exam or an in person exam. Those who had taken his classes before knew to never vote for the take home open book, but were always outweighed by the new folks. Hardest exams I took in college by a large margin

As someone who spent a few years teaching math, this would be a cause for celebration! I would have had a classroom pizza party the next day. This is creative usage of problem solving math that I could only dream about a classroom of students could come up with.
First mistake was to not specify a sheet size
This image… I don’t know if it is AI or it isn’t… but it certainly feels like AI…
It's listed on Adobe Stock photos[1]
I did find other similar photos[2][3] so it looks like it's an actual thing that exists. Actually found a listing for a 1 metric ton roll of it[4].
[3] https://www.alamy.com/stock-photo/large-paper-rolls.html
[2] is ai generated or so it says. [4] is real but not as big, and not quite a ton, it says '307kg'.
Most certainly ai generated, many things in the picture don't make much sense when looked at in detail. First of all, who would leave that absolute unit of a roll in the middle of the factory? With an axle inside?
It's getting ready to be lifted like this: https://www.123rf.com/photo_135982015_paper-mill-production-of-paper-rolls-for-the-printing-industry-paper-rolls-in-a-factory.html
The one thing that bothers me is the lack of chocks to keep it from rolling, but we can't really see in the black area, they could be there, or the floor could have an indentation or something
The photo is AI. There is a tag stating so, though it’s in French.
This one's real, but in the other one there's no crane nor rails for it, and there's no machine where it can go in like you see in the back of this one. I can't put my finger on it but I have definitely ai vibes looking at it. As other commenter has said the machinery around doesn't make much sense either.
As you've been proven wrong, this is a good time to point out that accuracy rates of humans identifying AI pics is ~50%, or no better than guesswork. Keep that in mind the next time you declare something AI. YOU might be the reason an artist quits their passion, not AI
As you’ve been proven wrong
I was referring to OP's statement about the axle, which somebody else pointed out is standard practice.
I'm not buying that given the second half of your comment. You're just trying to weasel out instead of apoloigising.
How have I been proven wrong? The other commenter posted a (real) picture of a similar thing, that proves that these exist (which I haven't put into question), not that the other picture is not ai generated. They even said that some detail bugs them, so no one has 'proven' the first image is a real photograph.
On the other hand, the poster of that link didn't say they're quitting art, just not posting it online. But even if that were the case, receiving (even unjust) criticism is part of being an artist.

That's how they make paper and a lot of other flat goods like tape. The manufacturer makes these gigantic rolls then there's this entire industry called converting where a company, a converter, takes it and process it down into a finished product. They may add adhesives, lamination or printing to it during the process.
You can go to a store and buy 3M tape but 3M doesn't actually make it like that. They make a 12ft wide, 10,000 ft roll that someone buys and forklifts into a machine that cuts it into a bunch of smaller rolls that you can buy
Those machines are referred to as slitters. I designed and built 2 for 3M Abrasive division back in the 1990's. Talk about a process that involves less than reliable hardware, (I never met an air bar or pneumatic web sensor I didn't hate), and enough wishful thinking to achieve the speeds 3M wanted them to run at that would make an Alchemist proud. I was constantly amazed that my designs even worked at all.
Called a Tambur, usally between 15-25 tonns. Reason not bigger / heavier is that then it starts to damage "crushes" it self.
Telltales: floor too shiny, machines on the sides dont make sense, inconsistencies in piping in the ceiling, random floating bits on the top right, a few big shadows that dont match the windows instead of many smaller ones
The spacing on the lights up top is super weird. AI seems to have a real problem recreating consistent repeated patterns.
OK, based on the comments, it's AI.
This one isn't. A sheet of paper from mythbusters.

Something something sheets are planar, but then also allow it because it's great.
Should get bonus points.
Are you, by any chance, subscribed to Kyle? 🧐
Yes, and I shamelessly stole it because it belongs here too!
Oh definitely! 🤭
