The teacher is fucking stupid. The question says Marty ate more, that is not only possible it is a given.

The teacher is fucking stupid.

The teacher is likely under-trained, overworked, and under-qualified for the class. Common in districts where the focus of the administration is driving down the cost of education rather than delivering the highest quality.

That is, of course, assuming this is a real homework and not some agitprop churned out by a Facebook group or a social media account more interested in generating outrage than education.

With the choice of marker, I'd say its rage bait.

I agree, the kid is correct. This is the only viable answer.

I have an argument like that in my calculus 1 class in college, it was an optimization problem but the professor never said that the optimization variable was a constant, so you couldn't differentiate it to zero and do the normal process that you typically do. So I just wrote that given that the perimeter wasn't a constant the area to optimize goes to infinite Givin x -> inf; y -> 0, without loss of generality. He marked me zero we discussed about it and I said that I don't care because I'm going to get a 10 next test if he didn't fucked up the question. At the next exam I made some stupid error but he still gave 9/10 for the overall class because he came to accept that he wrote the question wrong and I was the only in the class actually caring and giving the class some dedication.

"This is not possible because..."

This kid is never going to trust teachers again.

He was right. The question is not even worded ambiguously. It was just written very poorly.

Will the teacher admit that? Or is the expectation that this (likely neuro divergent) student should have just understood the expectations based on context clues or something?

[–] [email protected] 1 points 5 days ago

This kid is never going to trust that teacher again.

[–] [email protected] 9 points 5 days ago

Valuable lesson learned, trust yourself instead of authority ( I hope at least that was it and not start of self doubting ever after)

[–] [email protected] 5 points 5 days ago (2 children)

This kid is never going to trust teachers again.

If one bad response is enough to turn you off from anyone else teaching you anything ever, then you're carrying some enormous trauma that has nothing to do with a single math question.

If one bad response is enough to open your eyes to the fallibility of individuals and lead you to think more deeply about where you get your information and how you evaluate the correctness of a response, then you're going to go far and develop a much deeper understanding of the world.

Is there any reason at face value why the teacher’s answer is correct? From my perspective the teacher is an idiot and missing some basic math skills.

Marty ate 66% vs the other kid’s 83%, no way “marty ate more” with the information given.

[–] [email protected] 9 points 5 days ago* (last edited 5 days ago)

The question literally says "Marty ate more pizza". It's a foundational fact that you're given as a part of the problem. If refuting the basic facts of the question are on the table and the answer was the say "Actually, no he didn't" then you might as well say something like "No, he actually at 1/6 of his pizza" and claim all the numbers given are dishonest.

[–] [email protected] 3 points 5 days ago (1 children)

no way “marty ate more” with the information given.

that is the 'Expected' answer

[–] [email protected] 2 points 5 days ago (1 children)

So this is sort of a true/false math problem given to us, the viewer, out of context.

[–] [email protected] 0 points 5 days ago (1 children)

How is that possible?

"False"

🤷‍♂️

[–] [email protected] 1 points 5 days ago

By stating the answer given by the problem is wrong, and “showing the work” to demonstrate why it’s wrong.

[–] [email protected] 1 points 5 days ago* (last edited 5 days ago)

No. Within the parameters of the question it IS possible and the kid gave the correct answer.

A small fraction of X can have a greater absolute value than a large fraction of Y when X is suffienctly larger then Y.

I... Um... I've been looking at this for a minute and I can't tell why the answer is unconventional, nor what the fuck the teacher is on about.

[–] [email protected] 41 points 5 days ago

The kid answered correctly, it's not unconventional at all, the teacher is just stupid

[–] [email protected] 9 points 5 days ago

I'm actually not sure this is real. I've had some shitty abusive teachers but even they would be capable of basic logic.

[–] [email protected] 32 points 5 days ago (3 children)

It’s fucking dumb. No where did it say the pizzas are equal size. So the kids answer is just as right as her bullshit answer.

[–] [email protected] 37 points 5 days ago (1 children)

No, the kid's answer is not "just as right", it is the correct and expected answer. The teacher's answer is wrong and proof the teacher doesn't understand the question. The entire point of the question is understanding that fractions of a whole are relative to that whole and you can't directly compare fractions from different wholes like that. 5/6 > 4/6 doesn't mean Luis ate more pizza than Marty, it means Luis ate a larger share of his pizza than Marty ate out of his own.

But... The teacher is just flat-out wrong. It says right there in the problem that Marty ate more, and then uses that fact as a foundation for the question of "x is true, HOW can x be true". It'd be different if the question was "someone claims x is true; is it?"

lol this is actually a golden answer and that is why we need better teachers

[–] [email protected] 16 points 5 days ago (2 children)

In my experience this is how it feels to communicate as an autistic person

[–] [email protected] 3 points 5 days ago

Most threads on here remind me of that

[–] [email protected] 7 points 5 days ago* (last edited 5 days ago) (2 children)

Interesting, I'm autistic and what frustrates me here is that the question specifically asks you to posit "How is it possible" and the teacher insists that you're supposed to just say that it's not. Makes me want to just Calvinball the whole damn exam. 5 + 7, what is the answer? Purple. Obviously.

Given 4/6 x > 5/6 y therefore x > 5/4 y

Marty's Pizza must have been more than a quarter larger than Luis'. The kid is exactly right.

And the teacher is not flexible enough to engage outside their expectations for how the question was supposed to be answered.

Clearly the expectation was for the kids to take the unstated assumption that the two pizzas were of the same size, and reject the premise as unreasonable (note the heading "Reasonableness").

[–] [email protected] 6 points 5 days ago (2 children)

I'm pretty sure the kid's answer was how it was supposed to be answered

Now we know why teacher isn't teaching math, but they should definitely not be teaching reasonableness either.

[–] [email protected] 2 points 5 days ago

Marty ate some of someone else's pizza
