Idk why people think this is a bad thing. They are very obviously doing a unit on estimating. Knowing that the question doesn’t say “is 103-28 equal to 75” it says is it a reasonable number. You’re supposed to estimate (probably the point of the entire assignment).

Unless the class has been learning estimation and the test says “estimation” or something this would be silly however, having gone to school I know test usually cover what you have been learning in class so my guess is this is an estimation test.

MAYBE this is funny but there is no lesson here. We don’t know what the parameters of the test were and clearly at one point the answer given was different and subsequently erased and changed, perhaps before grading perhaps not. You can still see where the kid wrote “No” at first. So idk. Ha.. I guess?

This is something my boomer dad would post in Facebook because he apparently forgot he also learned how to round in the 3rd grade, and this was wrong then and wrong now.

I literally failed probability and statistics in college because of the same “estimate” bs. Problems that don’t have answers have answers that are finite for questions that should have finite answers. Genius level stuff.

This was testing estimation. He deliberately avoided the intent of the lesson. Still only got 1 point taken off for not following instructions. Complains about it being ‘unfair’.

This is literally showing understanding of mental math for checking if something is approximately correct. The student didn’t demonstrate an understanding of what the teacher was asking.

This seems like a failure on the question part, not the answer. I get they’re trying to teach the kids about estimating, but if that’s the case don’t give them a question where the two numbers they’re given *actually* come out to 75

Teacher – Uhm Jill is really struggling with her math accuracy. Today was the worst, she kept getting the answers completely correct. We might have to hold her back a year.

Okay, but how does subtraction give you a reasonable estimate of average either way? Wouldn’t taking an average be better? 🥴🥴
-Engineer, project manager 🤷♀️🤷♀️🤦♀️🤦♀️

Have seen some like this – this drives me nuts and the publisher of the question, and the teacher, should be ashamed. At a minimum, the answer given should be accepted.

I have also seen some like this:
Estimate 96 + 55
The “correct” answer is 96–>100 and 55–> 60 so “about 160”

My kid said: about 150…. I went high on the first one 96–>100, so went low on the next one 55–>50.
Pretty sound estimating logic there. But “wrong”

Education is so important.

Also in t-ball… 3rd baseman fields it…. Gets corrected by coach for making the force out at third… you are “supposed” to try for the out at first every time, to train the “basics” and because some kids don’t know the real rules about when it would be a force or tag or what. Never mind the chances of any kid at first catching the ball in time are SLIM. Kid made the absolute right play… and we tell him it was the wrong decision. Wtf.

Gimme a break… never tell someone the right answer is wrong because they aren’t supposed to be that smart yet. Ugh.

The lesson this quiz was based on, was it on estimation or subtraction? I do hate questions like this. Math used to be so black and white, now it is many shades of gray.

I had this exact thing happen to me in college (CS class). It was a multiple choice with answers in fractional form plus one entry for other and fill in the blank. I filled in the blank with the right answer in decimal form. Professor counted off. I fought it and she finally relinquished, but one of her arguments along the way was that the question had asked for an approximate answer and I had given an exact one. Wtf.

If there’s a header to this section of questions specifically asking them to estimate to the nearest 10, then this is fine and the kid did it wrong. If it’s just some out of the blue correction, then it’s pretty stupid.

Perhaps they need to teach when estimation is useful and when it is not. In this case getting the exact answer of 75 is trivial whereas constructing some approximate answer is a lot more work.

I haven’t put this in public record. in 1st grade we would race to finish math tests. basic math, mostly multiplication. id always win.

in honor of this ‘win’ my teacher gave me the power to grade the remaining tests after checking that I did get 100%. these wins came at a cost.

I learned to cheat, my handwriting worsened, and finally I lost a piece of my soul.

One person, would always be 3rd. Best handwriting in class. A True artist. Kendra would put a cross through her 7s. it angered me. id see these beautiful 7s and mark them wrong. I remember smiling about it, being evil.

why would you waste time when you can win? win at all cost. dethrone me, take my glory away. I do not deserve this power. I hate winning.

Never got reprimanded, she never changed her ways. I always finished first.

one day another person, Adam #2, was chosen to do math questions against everyone in class. first to answer moves on. easily beat everyone until he got to me. Then the teacher changed the format. instead of just numbers she used a word problem.

So and so has 5 apples, I take away 2 (3 my mind knows). How many apples are left?

I lost my voice. It was my first opportunity to speak up, but habit of not answering externally slowed my speech. I remained silent for the rest of the game. Adam won.

A) The Q doesn’t say to estimate. B) why estimate when simple subtraction will give the right answer? C) how is estimating 70 more efficient than calculating and reporting 75?

Even if they are asking for an estimate, rounding everything to the nearest 10, you can only say 70 is a “reasonable” estimated answer, you cannot say 75 isn’t a “reasonable” answer. Therefore it is not okay at all to mark the answer wrong.

Holy crap, the child gave the exact answer and you took that away from them?

I would have some choice words with that teacher if this were my kid.

​

This is literally why our children are falling behind in education. It’s more important to feel like you got the right answer than to actually get the right answer.

When did math problems become a problem of opinion of estimates? Math is math. There is an answer, add subtract divide multiply. Stupid things they teach our kids these days.

Government schools teaching kids how to be “good enough for government work” Don’t want to introduce any of these smarty-pants people into the workforce and make everyone else look bad.

Even of the correct way to do this is to estimate the numbers, wouldn’t 103 round up to 105. Then 105-30=75?

My guess is this is out of context, and the point of the exercise was to study estimation.

I can’t take this post at face value

E: Fake imo, handwriting is very similar (check the swoosh on their ‘s’)

Context matters, and is important to learn. If the test was on estimation then it’s reasonable to expect them to estimate…

It never asked for an estimate, only an answer. They gave the correct answer.

I can remember a time where actually no one defended nonsense like this.

Now I look at some comments and just fear the future even more.

carole needs to chill with all that reading

Idk why people think this is a bad thing. They are very obviously doing a unit on estimating. Knowing that the question doesn’t say “is 103-28 equal to 75” it says is it a reasonable number. You’re supposed to estimate (probably the point of the entire assignment).

The makes no sense. The logical answer is 75. But the question doesn’t suggest rounding as a viable way to do thing.

Is it just me or is it worded fucked up as well.

MAYBE this is funny but there is no lesson here. We don’t know what the parameters of the test were and clearly at one point the answer given was different and subsequently erased and changed, perhaps before grading perhaps not.

This can’t be real

This “New Math” is the reason why the younger generations are retarded. 103-28 will ALWAYS equal 75.

Classic education, didn’t do it the teachers way so it’s wrong.

‘merica?

This is why China is winning

Okay, but how does subtraction give you a reasonable estimate of average either way? Wouldn’t taking an average be better? 🥴🥴

If the instructions on the test were to round to the nearest 10, then I understand.

I had a stroke reading that

Common core bullshit

Arithmetic is for calculators. Learning how to estimate real time to make faster decisions is what people need in real life.

I’m sure the teacher has an excellent grasp on correct pronouns to use though!!!

Why should you have to explain a simple subtraction problem

Incorrect maths being taught in the classroom is a slight upgrade from activism being taught in the classroom.

Public education is a joke, and has 0% to do with how intelligent a person is as an adult.

Lots of black kids get graded like this.

28+103/2=65.5

We have 3 answers, 65.5, 70, and 75. Margin of error is within a standard deviation. Above answers are all REASONABLE.

I had this exact thing happen to me in college (CS class). It was a multiple choice with answers in fractional form plus one entry for other and fill in the blank. I filled in the blank with the right answer in decimal form. Professor counted off. I fought it and she finally relinquished, but one of her arguments along the way was that the question had asked for an approximate answer and I had given an exact one. Wtf.

“Students cheat because the school system values grades more then learning.” -Neil DeGrasse Tyson

In my day, her answer was the only correct one.

If there’s a header to this section of questions specifically asking them to estimate to the nearest 10, then this is fine and the kid did it wrong. If it’s just some out of the blue correction, then it’s pretty stupid.

Looks like you erased the original answer and wrote in an answer in fake kid’s handwriting. Same exact “S” between the Teacher and student

And people wonder why some parents prefer private schools…

If 70 is reasonable isn’t 75 also reasonable? Just like 80 would be reasonable as an estimate as well?

Change “pages of books read” to “hours worked this week” and you’ll understand why they are teaching this shoddy type of math.

Wtf is a reasonable answer in grade school math? It’s fucking elementary math there’s one answer for each equation.

If the job was to round and estimate then providing the exact answer would be ignoring the directions.

You didn’t use the trick to make an easy math problem easier. Fail

WTF?

i kept reading the teachers comment as a sick burn: instead of grade 100%, you get 70% , biatch.

I don’t get what’s wrong, he got it right

Who wrote the purple?

The purple is wrong.

Was that the teacher?

Maybe they should smoke Ganja before grading papers?

seems like OP has a hard time estimating the quality of education

Nothing about any of this is reasonable. Must be American education.

When teacher can’t math

Perhaps they need to teach when estimation is useful and when it is not. In this case getting the exact answer of 75 is trivial whereas constructing some approximate answer is a lot more work.

Event if you round values for your calculation you should also compute how wide is the margin of error.

If you simplify rouding, sayting that 5 can be rounded both to 10 or 0

A (+/- 5) + B (+/- 5) = C (+/- 10)

Then any value within 85 and 65 would be within the margin of error.

She read 28 pages on Monday.

She read 75 pages on Tuesday.

She read 47 MORE pages on Tuesday than on Monday.

Why would you estimate such a simple sum?

I haven’t put this in public record. in 1st grade we would race to finish math tests. basic math, mostly multiplication. id always win.

Thank you

A) The Q doesn’t say to estimate. B) why estimate when simple subtraction will give the right answer? C) how is estimating 70 more efficient than calculating and reporting 75?

Okay, even IF the instructions were to round to the nearest 10, it’s still ludicrous to take points off for getting the answer right.

This doesn’t enforce “doing math in your head” it enforces “do exactly as you’re told, even if it’s wrong”

Even if they are asking for an estimate, rounding everything to the nearest 10, you can only say 70 is a “reasonable” estimated answer, you cannot say 75 isn’t a “reasonable” answer. Therefore it is not okay at all to mark the answer wrong.

6+5=chairs

I HATED these growing up. Why is the right answer wrong, and the “close enough” answer right? I ALWAYS got them wrong.

This teacher should be fired.

Holy crap, the child gave the exact answer and you took that away from them?

I would have some choice words with that teacher if this were my kid.

​

This is literally why our children are falling behind in education. It’s more important to feel like you got the right answer than to actually get the right answer.

EsTiMaTe!

75=70, teacher still wrong

Or if you’d rather, 75=80, in which 70 is wrong

When did math problems become a problem of opinion of estimates? Math is math. There is an answer, add subtract divide multiply. Stupid things they teach our kids these days.
