Help me understand my son's homework.

Had a common core joke been made yet?

I think we've got that one covered, but I haven't seen a 1911 / glock joke or head on a swivel joke yet if you want to cover that base

I didn't say they intentionally left it out. It's clearly flawed - they omitted the right answer. I have had errors in answers in college and grad school texts as well. What does an error have to do with common core?

Well, common core, in this case has no common sense. Like you said, it is clearly flawed.

pullstart has it right.
There is no correct answer among the choices.
Teachers are human and sometimes make mistakes.
Likely cut and pasted the answers from another question for the format/template but forgot to change the answers.

The good thing about this question is that there are many ways to solve it.
The method that pull start is the most simple and easiest.
You could get into dividing data at the given points to generate a solution.

Unless the teacher required that you show you work and dictate that you use only a single prescribed method for the math (Common Core foolishness), there's no common core issue here.

The beauty of an question like this is that are are many ways to solve for the correct answer.
Every person has their own way of solving. Some are more visual and the graph is great for that, some find the math easier and you can use it too.

Also, not having the table of information presented with the same units as the answers is not trick.
Converting metric units is easy, a real like part of dealing with materials, and a basic skill required.

Unless MrBullRed's son goes to one of the handful of schools who opted out of following the Common Core curriculum (and getting the $ that goes along with it), then it is most likely is a common core issue.

I'm also the parent of a 7th grader and can relate with him 100%. I've spoken to Dr. Jan Lancaster (Superintendent of the Nola area Archdioscen schools) enough to get a full understanding of CC in Louisiana. Most of the curriculum is not "cut and paste", but all issued from a handful of vendors that have the textbook accessible online in addition to the hard copy.

Add in teachers who are not prepared to teach the curriculum (only follow the directions they are given) and homework is sometimes the parent doing the teachers job to teach the material. I'm young enough to remember all the math, but I know plenty of grandparents raising teens and they're shelling out to tutors a few days a week ($20/hr is the avg rate).

Rant over.

BTW, one of the blocks has a mass of zero and volume of zero which is impossible. The teacher is an idiot. Please post the teacher's name so we can protect the rest of population from idiocy.

At my kids school (anti common core), they started teaching 'Singapore Math'. Seems bass-ackwards to me!

They also invented an ocean and got rid of a planet since my school days!

Why do they have to change stuff???!

Answers have been wrong in text books for as long as I can remember. What is the difference between this typo and any other that makes this one such a big deal?

You are correct on that; but here is a contention of mine. Being heavily involved in my younger ones homework, I have noticed numerous errors on worksheets including misspelling, grammatical errors, wrong answer choices, no correct answer choices, etc.

To me; those worksheets should NEVER be wrong! Why? Because these are the people teaching our kids. If they are THE educators, and they are THE source of curriculum; shouldn't some one be proofreading this stuff? Someone that possesses the intelligence themselves, to notice the errors before every kid in America sees the sheet.

I am there to explain why my kids brain is not the problem when he can't figure out the correct answer on an incorrect worksheet, but can't be there when he is testing, and getting really upset when he knows the process of the question being asked, but is not coming to the correct conclusion due to incompetent worksheets.

It is important! How can you routinely have spelling errors on school worksheets? I take a harder stance! I get incensed! I have my kid's principals' mobile number (at his request), and I text him screen shots of every mistake I see on a worksheet. It's a lot!

FWIW: The worksheets come out of some company in New York that is the "go to" source for the CC curriculum. To me, that is a problem in and of itself.

There is a profit motive (someone got a government contract), and an agenda.

Gives knuckle draggers something else to bitch about.

Take a look back 20 years where if the kids did bad in school they were disciplined. Today the parents seem to blame the teachers. Just like anything else you can tell who helps their kids with their homework from those that don't. Their grades show it and while it is the teachers job it's also the parents responsibility to make sure it gets done. Teachers only have the kids for a few hours a day.

Just like anything else school curriculums are always changing. Trying to become better some **** doesn't make sense. Think back when you were a kid I bet a couple of your parents had no idea how to do an algebra problem.

7th grade. It didn't come from a workbook it was a worksheet on his school issued ipad.

He had another problem on that same lesson that the numbers and equations worked correctly but the picture of the angles are misleading. A is supposed to be 49° angle but if you look at it with the common sense approach knowing that the entire angle is 90° there is no way A visually is correct. Use graph on 26 but 27 is the word problem in question. Take a look.

It is not uncommon to have this type diagram when dealing with angles. The idea is not to sketch the lines where they actually should be (and not to intentionally sketch them wrong either) but to use it as more of a schematic, and the words actually explain the specifics.

There is no issue with this particular problem.

I don't disagree with much of anything you're saying, I just don't think that the ideas behind common core are the problem with errors on these worksheet. Not defending common core, just think we should assign blame correctly.

You are right! I don't care who did it. I want them to be correct. It's conflicting on these kids, and it's lazy! It's says, "Accuracy is not important!" Just do as we tell you kind of crap!

I am trying to find the one glaring example worksheet that I had last year, that was really troublesome.

Yeah, I don't know the extent of the errors, but I'd they are as numerous as you are saying I'd have an issue too. We shouldn't be holding kids to a standard their learning materials can't maintain.

That's all I'm feelin!

I'm actually shocked it's not a bigger issue?!?

Someone alluded to it earlier; perhaps not a lot of parents paying attention. Christ, I hope it's not that people just don't care enough!

Think back when you were a kid I bet a couple of your parents had no idea how to do an algebra problem.

Happened to me. I actually had to teach my parents how to do algebra. Did that make it a bad thing that we learned it? Nope. I use the concepts that I learned with algebra in my job every single day.

I don't see what people's big beef is with common core. It's just a different way to do the same thing, and watching my daughter (granted she's only in kindergarten, but they've started teaching the math curriculum already) do her homework, I can absolutely see how it works. Not that it's better or worse than what I learned growing up. I just can't see how it's this great evil, socialist-led indoctrination, that I see parents posting about on facebook all the time. It's just doing math differently from the way that you learned to do it.


On the other hand, if errors in school books are as common as Emp is saying... then yeah, that's a big problem. Everybody has a bad day at work once in a while, even writers and editors, but it shouldn't be a consistent thing.

 

[AustinBR]

Being still in school, I can vouch that there are typos and grammar errors throughout. A few of my teachers are not native English speakers and their writing definitely make the easy to see. No matter how good the editors, books will have typos. It's just not a big deal.

Oh there's a bias in it! Anti-2nd Amendment! Anti fossil fuels! For two of the biggest as starters. I've also seen some instances of steering the debate of climate change as undisputed fact!

Interestingly enough, many reputable hard core critical thinking climatologists are not on board with that! But special interest and left wingers are! Gee, I wonder why?

Are you saying that climate change isn't a thing? Not that it's caused by humans, but that it actually occurs? I can't tell from your post.
