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

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"?

How ruined the question

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

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.
