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.
This is genuinely baffling. What was that teacher on.
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.
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 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.
Neither is right: written text is not people, and text without people is either right or wrong until someone read. Only people reading can make the text true, also, you’re a moron.
…it’s just a joke, jeeeez.
You know we wouldn’t even really need fractions if it wasn’t for your stupid inches and feet right?
Metric countries have no real use for them
I sincerely hope that was a joke…
This post shows the difference between school and education. The school system is there to get a child to be able to regurgitate whatever the lesson says they should. Education is to develop knowledge as a whole.
It is sad that the teacher was not even able to consider the flawed nature of the question, because they are trained to just see if the student’s answer matches the answer key for the test.
In many cases, the public education system no longer exists to deliver educated graduates. It exists to feed itself – to obtain funding for itself the next year and to support a gradually expanding set of “administrators” that add little to the process.
Look at the effects of “No Child Left Behind”. NCLB pushed test scores above all else. What did we get? A bunch of students that were very good at passing standardized tests. That does not necessarily translate to a better educational outcome. The value in the skill of passing standardized tests plummets rapidly once one joins the workforce.
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.
Well the teacher’s answer is flat out wrong which doesn’t surprise me at all.
This is literally a trick question.
No it’s not, it’s rage bait.
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.
Right? He’s rationally explaining how that was possible given the question of “how” it is possible. In my opinion that question was written poorly.
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.
No. The teacher did not have it wrong. Does not mean the student is right … Marty and Luis both had their own pizza. Marty had a big pizza and “only” managed to eat 4/6th of it. Luis had a small pizza, and “only” managed to eat 5/6th of his. If you want to give a nitpicking correct answer: a single pizza does not have (4 + 5)/6th pieces. x/6th implies the pizza(s) were divided into 6 parts … so: it can only be 2 pizzas.
I’ve read this a few times and I’m genuinely not sure I understand what you’re saying.
4/6th is a smaller ratio than 5/6 the only way for 4/6 to be greater would be for the area to increase.
Expressed as percentages it would be 66% (approx) eaten vs 83% (approx) where the person that ate 66% ate more pizza. The only way that’s possible is if the area of the pizza that 66% of was consumed was greater. (Strictly speaking the volume could be at play here too but I’m going to assume they’re the same height for the question).
I genuinely don’t see any way his thinking was wrong, or how this could be answered another way.
I might genuinely be missing something but if so this question is poorly worded.
They’re just doing the same thing as the teacher and assuming the two pizzas have to be of equal size and therefore it’s an impossible situation.
Yes, it can only be two pizzas. The question is “how is this possible” which is correctly answered by the student. The teacher talking like that’s not how pizza works, is indeed incorrect.
4/6 of a 10” pizza is more pizza than 5/6 of a 6” pizza.
Ah, a teacher that does not comprehend the barometer
Two other right answers:
- Luis’ pizza is at least <whatever is the correct fraction> 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”.
Well the question does assign ownership to the pizza, so Marty can eat his pizza then give it to Luis making it his pizza
correct fraction = 4/5, as in, Luis’ pizza is smaller than the 4/5 (80%) of Marty’s pizza.
The statement and question make perfect sense. The kid has the only “reasonable” answer.
The statement and the question do not make any kind of sense. Would make more sense to ask who ate more pizza when one ate 2/3 and another one ate 3/4 of an equally sized pizza.
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.
