This is bizarre. The info provided in the question was that Marty ate more than Luis, the question was how would that be possible given that Marty ate 4/6 of his while Luis ate 5/6 of his. The answer the kid wrote (Marty's pizza was bigger than Luis') is the only possible correct answer.

The grader is asserting that the information given in the question was wrong and that "actually it was Luis who ate more pizza"--even though it stated as a premise that "Marty ate more". How are you supposed to give a correct answer on a test if you are expected to accept one premise (proportion of pizzas eaten) while disregarding another premise (Marty ate more than Luis)? How do you decide which part to disregard? Would they have accepted the answer, "Luis actually only ate 3/6 of his pizza, not 5/6)"? Wouldn't that be just as valid an answer as "Marty actually didn't eat more than Luis"?

Agree, this question is such hot shit that I can't imagine it popping up in any real world maths test

[-] [email protected] 5 points 1 day ago* (last edited 1 day ago)

The question is good, how given one smaller and one larger fraction could the person eating a smaller percent still have eaten more total pizza? That's a fun brain puzzle.

The problem is the teacher.

And by gaslighting the kids, they're teaching them not to trust their own ability to reason, crushing their critical thinking skills. It sets them up to submit to authoritarianism and go along with obvious lies instead of trusting their own senses and questioning authority.

This is genuinely baffling. What was that teacher on.

[-] [email protected] 17 points 1 day ago

that kid passes my class with honors

the teacher is a moron

[-] [email protected] 10 points 1 day ago

Same. Question sucks. Teacher is a tool. Kid needs bonus points for a creative solution.

This always pissed me off about all formal school. They don't want a good answer, they don't even want the correct answer. They want you to give them the answer they previously told you to give them, regardless of all other factors.

Real life doesn't work like that. In reality, the "correct" answer is anything that completes the objective. In this scenario, the answer provided was reasonable, logical and most importantly, it was not incorrect.

[-] [email protected] 4 points 21 hours ago

Curriculum and unappetizing methods of teaching are the problems.

This kid has the right to question, to speak out what's really logical, and is likely to be more street-wise.

[-] [email protected] 31 points 1 day ago

The title of this post is disappointing. The given answer is sound and it seems safe to assume it was arrived at by thinking mathematically.

I suspect many commenters are missing the point, the student's response can only be the correct and expected answer to this question. Teacher has it wrong.

Ah, a teacher that does not comprehend the barometer

Two other right answers:

  • Luis' pizza is at least smaller than Marty's (which is basically the same answer as the kid's)
  • Marty ate someone else's pizza besides his own

And, for funsies:

  • Luis' pizza is 50% crust, so it doesn't fully count as pizza
  • Luis doesn't like pizza and actually fed the dog while nobody was looking
  • Marty is many years older than Luis, therefore he has eaten many years' worth of pizza ahead of Luis

This is completely unrelated but I cannot believe Calandra is a real world name.

The designers of the video game Path of Exile should've called their super rare item "Kalandra's Barometer" instead of "Kalandra's Mirror".

[-] [email protected] 2 points 22 hours ago

Well the question does assign ownership to the pizza, so Marty can eat his pizza then give it to Luis making it his pizza

The statement and question make perfect sense. The kid has the only "reasonable" answer.

[-] [email protected] 21 points 1 day ago

Commendable for the kid to be thinking outside of the box, and a bit shitty of the teacher for not giving them maybe half a point (because it's a correct answer, but not the correct/expected answer). The test maker is also to blame - they should've taken care to eliminate all ambiguity - it's a math test after all.

[-] [email protected] 33 points 1 day ago

The teachers response is incorrect. It is stated as fact that marty ate more pizza.

The kid's answer is the only correct answer. It's not half right, or 5/6 or 4/6 right. It's the only correct answer that fits the question. The teacher is a moron who has no business in a math classroom except as a remedial student.

Actually a kilogramme of feathers is heavier, because you have the weight on your conscience of what you had to do to those poor birds to get all those feathers.

i can't fathom this being real, most probably this was made for karma farming or something.

[-] [email protected] 24 points 1 day ago

Teachers like this exist. One of my kids had an elementary school teacher like this. Two examples:

  1. The math assignment was about currency denominations; what coins and bills you need to make up $7.42, for example. My kid answered using $2 bills (uncommon in the US but still printed), as we have them at home. Teacher marked the answer wrong because teacher didn't mention $2 bills in class.
  2. The writing assignment was to rewrite the Snow White story from the perspective of another character. My kid, having read a bunch of those "twisted tales" and recently fallen in love with "Wicked", wrote from the evil queen's perspective and made her a sympathetic character. Teacher marked her down for "changing the story" without acknowledging my kid's creativity. Teacher did not back down when we confronted her on this during our parent teacher conference.

(FWIW, in both cases we reassured our kid that they did great in both cases, and that we were proud of them.)

Teacher : draw a triangle with sides of length 1 inch, 2 inches and 3 inches

Kid : but you can't do that. You get a 3 inch line. Other students proceed to draw skinny triangles.

Teacher : you're wrong Kid. Everybody else can do it, what's your problem?

True story.

Teachers that don't accept an unexpected but true answer are not teaching. The test taker had a correct take, one of the pizzas could be bigger than the other. It was not specified in the question. I am so glad I am out of school

[-] [email protected] 14 points 1 day ago* (last edited 1 day ago)

This answer shouldn't have been unexpected, seeing as how it's the correct answer.

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

[-] [email protected] 83 points 2 days ago

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.

So this was a trick question? Because the student's answer is correct. That's the only way it's possible. Was the answer supposed to be that it's not possible? I'm a grown adult and I find this question unclear so I'm surprised this was asked to a young child in this way.

[-] [email protected] 5 points 1 day ago

Well the teacher's answer is flat out wrong which doesn't surprise me at all.

When I was in elementary, my teacher said that "Lutetia" was how the Romans called the city of Liege. As an avid reader of Asterix comics, I knew this isn't true and corrected her and said it was the Roman name of Paris. She insisted that it is Liege. Anyway, the next day, she came back to class and said that she looked it up and that I was indeed correct and Lutetia referred to Paris and gave me a chocolate bar and told me to keep reading comics. Good teacher.
