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.
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
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.
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
This answer shouldn't have been unexpected, seeing as how it's the correct answer.
It really seemed like my fellow students lost their interest in math as we went through the grades here in the US.
I still remember a kid in 2nd grade who learned how Roman numerals worked because they were interesting. By grade 6, actively detested math.
Curious.
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.
i can't fathom this being real, most probably this was made for karma farming or something.
Teachers like this exist. One of my kids had an elementary school teacher like this. Two examples:
- 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.
- 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.
If you state that Marty ate more as part of the question, you cannot answer in any other way, because it denies mathematical logic here. You introduced a lie as part of the problem, and if I need to decide myself which part of the statement is a lie, I can pick whatever I want, let's say, Marty didn't ate 4/6, but 6/6. This teacher should be taken to the gulag.
Yeah, this is answered exactly correctly, and also demonstrates that the child has a strong grasp of how fractions work. 3/4 of 2 is greater than 4/4 of 1, even though 4/4 is a larger fraction than 3/4.
that kid passes my class with honors
the teacher is a moron
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.
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.
The kid answered correctly, it's not unconventional at all, the teacher is just stupid
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.
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?"
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
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").
This is genuinely baffling. What was that teacher on.
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.
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.
The statement and question make perfect sense. The kid has the only "reasonable" answer.
This brings back memories of when I realized that I was smarter than most of my teachers.
I can't find it now and I do not think it really applies here. But someone stated that being high IQ could lead to academic problems as the high IQ learner would understand or see things that the professor could not causing the professor to mark it as incorrect.
I guess this is the idiocracy version of it.
A good teacher sees being corrected as a learning experience, and encourages their students to question them respectfully.
Bad teachers see it as a challenge to their authority.
"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?
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.
Some real "steel is heavier than feathers" energy coming off this teacher.
Math education in the empire is TERRIBLE. There is no actual math taught. At best it's applied analogies like this pizza BS. The teachers have never taken any advanced math so they don't even know what they're not teaching. The goals (eg. calculus) are completely worthless. The entire system is stuck in the 1700s. It's a complete failure. It's intentional too. The goal is creating obedient, little computers not critical thinkers. That would be a threat to the system. This image is just the tiniest tip of the iceberg.
Marty's pizza is larger. 4/6ths of a 3kg pizza is more than 5/6ths of a 1kg pizza
