Common Core Hate Thread (I have a Algebra II Test coming up this week)

>>8112168
Common core exists to diminish the divide between whites/asians and blacks/hispanics.

Prove me wrong.

Holy shit common core is terrible. How old are you americans when you learn derivatives?

>>8112208
i think for the average person it would be sometime around freshman/sophomore year (9th/10th grade)

>>8112193
here's what you do:

add 1 to 316 to get 317
add 10 to 317 to get 327
add 100 to 327 to get 427

100+10+1 = 111

signed, someone never indoctrinated by common core

>>8112193
is this a cringe thread?

>>8112208
>derivatives
That's the old way. Now they pick 2 points and calculate the slope of the line linking them.

>>8112212
Anyway, it's still retarded doing a 3-step process to do an operation given by a table. I wonder how do they multiply or divide.

>>8112211
WTF my school didn't let me take calculus until senior year

>>8112226
seriously? i was doing calculus my sophomore year. did you only have one level of calc?

>>8112208
between 16-19
16 if your smart and your high school offers it
17 if your smart and your high school has mediocre resources
18 if your high school didn't offer any resources or you choose to ignore them
19 if you go to a shitty community college or degree since you would have to take "college algebra and trig" first

>>8112227
Yes. only 1 class for the AP Calculus AB test.

We had to take
9th: Algebra 1
10th Geometry and Algebra 2
11th Trig
12th nothing or Calculus AB
(and this was the "advance" schedule)

The sad part is that the people that ended up taking it took it only help their ranking and the teacher never taught but relied on youtube, and only 3 people ending up taking the stupid test(including me)

>>8112235
That's absurd. We had all the way up to multi variable IIRC.

This x2.

The problem w/ common core is that it tries to teach superior intuitive understanding to people brought up by parents who did rote learning.

>>8112183
It's of the same order of magnitude, how much more "reasonable" do you want?

>>8112168
I've always done math like that. Did I invent common core?

>>8112168

>>8112328
The problem with the shit in OP (and other such pics) is that any kids who weren't doing this anyway are thick for life, and the rest of the kids are now conscious of following a rigid set of instructions.
>>8112183 is bad too.

>>8112496
>any kids who weren't doing this anyway
By "this" I didn't mean to narrow it down to the method in OP. I never "made 10s", I simply know what 7 and 6 make. Don't kids learn multiplication tables anymore? If a kid knows products up 9x9 they can fucking remember sums up to 9+9.
>America

>>8112211
Sadly this is not the reality in America. Most kids won't even take a calculus class in high school. Of those who do, most will be AB calc which won't teach them much. The average grade for a student who takes calc is probably 12th grade because of how behind we are in mathematics.

>>8112572
? The AB calc class I took in high school was pretty rigorous. We learned the same, if not more than a 4 year uni.

>>8112175
it's about class, not race. plenty of poor/stupid white people making babies too.

and this argument applies to standardized education in general. common core is not the be all end all. there are plenty of other approaches (cf finland, considered the best, or at least one of the best, educated country in the world, despite having no homework or high stakes testing)

How is that in any way helpful? Had the kid reached a result of 545 by mistake, it would have appeared like a very reasonable number by those standards.

This is shit is so stupid it's hurting m brain. How is this in anyway beneficial to students? Why was this introduced? Is the US just generally dumb country?

They tried something similar back in the 60s, called "New math." I guess we never learn.

>>8112168
Common Core doesn't look too bad. It's just people looking at things designed for kids and their ego suddenly rising when a simply subtraction problem is in sight and they can just say the number.

Basically they are just trying to teach kids how to operate on numbers beyond just memorization and finger counting. Of course it's obvious that all those methods seem simple to anyone out of High School or even still there.

It's not like later in the educations kids aren't supposed to do similar things like simplify expressions under square roots.
>>8112180
Is pretty much just taken out of context where probably a few questions before they explained what making 10 means.

>>8112629
We have something called Project Maths being introduced in Ireland which tries the same kind f thing but it's no where near as dumb as this. Won't this just cause a huge divide between common core students and algebra students? Lots of dumb kids could just coast through school on this and learn nothing bu make believe maths.

Sure smells like /pol/ in here

>>8112168
Nobody but retards actually adds things in his head with the method you learned in school. Common core is trying to teach kids to do them the same way non-retards do in their heads so they too can do it in their heads eventually.

>>8112242

None of these things people are hating on are "common core." Common core isn't a new way of teaching math is a list of standards which can be found here http://www.corestandards.org/Math/. No one in the standards will you find any of these math problems or pedagogies. I'm not sure where these memes come from. I agree these are retarded but they don't come from the common core standards. You guys are just making yourself look like retarded moms on normie book who just repost shit without even checking to see if it makes any sense.

So the old traditional methods can still be used? That seems fair. As long as they din't shove it down our throats, I'm fine.

>>8112605
>Soft degree seekers will never see a derivative in their life.
What about gen eds? Do you mean to say they get away with non-calculus based physics (if they even take physics and not, say, biology) and that's it?

>>8112877
>Do you mean to say they get away with non-calculus based physics

Not that anon, but yes. Humanities/"Soft" degrees at my school, for example, only have to take up to "College Algebra" as their highest math course(which is literally just a repackaged High School-level algebra 2).
For their Gen Ed science classes it's more or less the same repackaged high school-level physics/biology(so if there's any calculus involved, they likely have no idea).

I don't see the problem with common core. In fact, it seems like a definite good thing. It teaches how to think like I had to realize and teach myself. Who does rote algorithms in their head? No, we use intuition and different representations of numbers and so on to quickly arithmetically manipulate numbers.

Common core seems to be much closer to teaching how to [math]think[/math], rather than how to blindly manipulate expressions with memorized algorithms. It is absolutely closer to how math should be taught.

26 + 17 = 43
23 + 20 = 43
I already do this in my head without common core and the process doesnt fucking need 5 steps.

>>8113254
Most people would do the carry-one nonsense without common core. Most people on this board realized how to think on their own. In contrast to traditional math education, common core seems to not so much teach algorithms, but rather how to think. It's not as if you have to think about it the way presented in OP. It's just a particularly spelled-out example of the thought process, to guide students toward understanding, synthesis, and any quick mental arithmetic that happens to result therefrom.

>>8112208
Depends. 17-18 for most people. Most people not in STEM never learn them.

>>8112242
I've never even heard of a high school teaching multivariate calc in the US. Everyone I know had to go to a local university to take it. My school didn't tell us this so I graduated with only calc 1.

>>8112544
It's not about these babby-tier additions. The common core method of making 10 works no matter how large the numbers are.

Sure, you should know your multiplication and addition tables up to 9, but how do you add or multiply 3-digit numbers without making 10?

>>8112199

It is the laws of a (democratic) state which must be obeyed, not the government.

>>8112168

>>8112178
>>8112179

People hate the math parts because they weren't there in class to hear it explained. They know only their carry-the-one method, and anything else confuses them.

>>8113254
Most people are fucking morons though.

One time I was having breakfast with my sister (sociology major), and we were about to leave the tip. She didn't have her phone on her, so I explained that all you need to do to calculate 20% of something is multiply it by 2 and move the answer over a decimal place.
It blew her goddamn mind.

Teaching the relationship between numbers instead of just shoving a shitload of multiplication tables down their throats can only be good thing as fara as I'm concerned.

>>8112189
Wtf is this even asking

>>8113424
>People hate the math parts because they weren't there in class to hear it explained.
Exactly this. They see weird wording that doesn't mesh with how they learned and don't stop to think that teachers beat problems exactly like that into the kids' heads all day in class.

Unless they changed it since I was in high school, your typical dumbass student would do:

Most people that were not complete failures would take Pre-Calc senior year, but I am pretty sure you only had to pass Trig to graduate.

Most students that gave a fuck did:
7th - Introductory Algebra
8th - Geometry
9th - Combined Intro Trig/Pre-Calc class
10th - Calc 1
11th - Calc 2
Or push everything up a year

Then depending on what major they were planning to go into they might do Calc 3 (multivariate) senior year

They probably left off some information above about how many friends she has, and how many stickers are in a bag.

>>8113567
>Are you implying 'making 10s' is easier mentally? I think it creates more numbers than carrying.

It is the way I've been thinking of math for as long back as I remember - far easier than when I try to mentally "carry the one" or some such bullshit.

>>8114699
I don't think they did.
I think they literally just want you to select the larger amount.

>>8114702

It is also the way I do multiplication in my head. E.g.:

423*245 = (420+3)*(240+5) = 420*240 + 3*240 + 5*420 + 3*5

And if I'm tired, I break it up again

400*200+20+200+40*400+20*40 + 3*240 + 5*420 + 3*5

This is obviously not how I'd to it on paper, where it is instead

400*245
+20*245
+ 3*245 =

Nah, you need to know the actual number of friends and stickers/bag if you are to solve this one.

>>8114717
What I mean is that I think, is that they want you to come to the conclusion that "6 bags is more than 4 bags and therefore the safer option".
Since they don't provide any information about either friends or stickers.

I agree that hiding zeroes is misleading to what is actually going on, but the rest seems like crying about formatting. All that matters is that you're splitting up the operation in a valid way and using laws of associativity.

Which is maybe what we should be teaching in the first goddamn place. It's as stupid as OP where children would probably follow a lot faster with: 26 + 17 = 26 + (4 + 13) = (26 + 4) + 13 = 30 + 13.

The claim that the author of those images is incapable of adapting to an alternative method of elementary arithmetic gives me concerns about his position.

Still, since by posting these you claim the logic of "the old fashioned way" is easier to follow, I'm curious if you can give me a resource on those.

That's actually pretty funny. Unfortunately, the point would probably be wasted on those complaining about Common Core.

>>8113251
>It teaches how to think like I had to realize and teach myself.
This is exactly the reason why it is bad.

Can someone explain what this common core things is to a eurofag and why seemingly every american hates it?

By skimming over the thread it just seems like a bunch of math done retarded

Obama implemented this way of teaching Mathematics as mandatory for all schools across the US or they lose access to federal funding.

>>8115366
>>8115377
To break it down:
It was declared as a condition of federal funding for schools that public schools in every state had to agree to teach the same basic skills in the same basic way at the same grade level, where before every province of the US could institute its own methods.
The people in charge of hashing out this communal curriculum decided that the best thing to do was to teach people to do simple math the way that people who do math in their heads do the math in their heads. This was supposed to make mental math easier for normies, who use a system that calls for paper.
Unfortunately it turns out that the kind of person who's good at mental arithmetic is good at it because they think about numbers in a really counter-intuitive way, and if you just try to teach mental math to normies like it's a skill they flail all over the place clapping and screaming.

>>8112850
Common Core meant schools needed new textbooks. These are the new textbooks they got.

>>8113567
The making tens trick lets me do addition using words, instead of creating a mental picture. Since I (and a statistical majority of Americans) am not very good at forming mental pictures, it is easier to say the problem out loud making tens than it is to hold a stable image in my head while also doing math to it.

>>8113582
Here is how I do it 26+17=20+10+stuff=30+stuff
where stuff =6+7=13, so you get 30+13=43. That's exactly equivalent to carrying 1, and "carrying one" is one of the staples of a positional decimal system.

>>8114889
"New Math" came out in like the 80's, where math the way you learned it replaced the old way to do math, as seen above. The joke is that people were just as mad about the math "you" think is totally intuitive, because everyone grows up thinking math the way they learned it for 11 goddamn years is perfectly intuitive.

>>8112648

The method is just so massively convoluted, and could not be applied to larger numbers. What's wrong with teaching long addition?

>>8112189
>Number bonds

It's just fucking addition

Are you not visualizing what you see when you add from one side to the nearest 10?

What does saying something out loud do if it isn't helping you visualize?

>Americans not very good at forming mental pictures
>statistical majority

Are you a teacher? Politician? you'd fit in perfectly

7 and 9 are trivial, but I don't get 8

What the fuck is this. Im fucking ashamed.. Im sitting here looking at this and cant believe my fucking eyes. ARE YOU SERIOUS. I cant even figure out what there doing.

>>8116677
7 is actually underdefined; you have to make assumptions about the angles in order to solve the problem. If those triangles aren't isoceles then all of the relations listed could still be true while ending up with a different area. But that's pretty nit-picky, to be honest.

>>8116739
I figured that since this looked like a low-level assignment they were assumed to be assignment

>>8112208
i learned derivatives in 11th or 12th grade i don't remember, and that's only because I signed up for nothing but advanced courses.

in 12th grade some of my mates were taking pre-calculus which is nothing but trig

hell if you're not in a STEM field in college you don't see derivatives at all since the most advanced math you need is "college" algebra

it's pretty fucking sad

>>8115397
>Unfortunately it turns out that the kind of person who's good at mental arithmetic is good at it because they think about numbers in a really counter-intuitive way,
Completely disagree, it's entirely intuitive. However, the plug-and-chug teaching method MAKES it unintuitive, because students are taught a list of steps with no explanation of how they are simple distillation of decimal notation and associativity. 55 * 44 = (5*10 + 5) * (4*10 + 4) which can easily be rearranged into simpler steps.

The curriculum itself, in my experience, is not the issue. It's the way every piece of curriculum is introduced, with absolute minimal explanation. I discovered the visual proof for the area of a non-right triangle outside of school. That's fucking pathetic.

>>8117221
Don't get me started about this. My non-standard high school didn't have AP. I dropped out after two years when there were no more math courses and went straight to community college for calculus to not be left behind. I think it's disturbing that we consider calculus a STEM-only subject, the basics of derivatives and integrals gave me so much intuition for the laws of physics.

I skipped all of middle school, did anyone learn any math there? I played videogames all day and didn't fall behind.

>>8113569
So you recommend starting with set theory and slowly working primary school kids up to understanding completion of sets?

Why do people need rigorous methodology to calculate such results? I am fairly sure anyone with a functioning brain can look at '26 + 17' and see it is 43, no thinking required.

>>8117303
Not that anon, but, your hyperbole contributes nothing to the discussion of two different methods. Besides, the way it's actually taught, both methods are a plug-and-chug algorithm and equally bad. That being said, you can do foundations without going into analysis. You know, the way we did before we invented analysis?

You actually don't need to make any assumptions.
What are you on about?

>>8117248
My middle school had us doing algebra and geometry, so we could jump straight into trig then calculus in HS.

Looking back, it was very strange for some random, public school in the middle of the fucking ghetto to be two years advanced in Math/Science/History/English. I guess our principal was really fucking ambitious.

I honestly think the whole curriculum needs to be reworked. Students who show a propensity for math should be taught on an accelerated program. Programs like No Child Left Behind and the like teach to the lowest common denominator.

>>8112629
That new math is math now retard, its what all under 40s learned in school

>>8117449
Wouldn't it be great if we identified actual interests and talents in education? Math was fucking easy for me and I'm an "above-average" reader with "above-average" writing but history and literature courses drove me nuts. I did fine at re-wording the reading material to respond to questions of reading comprehension. I was shit at reading between the lines and more meaningful questions.

I'm not suggesting I should have been able to avoid those subjects completely, the same as I still claim that EVERYONE should eventually learn about derivatives and integrals in their education, but I feel it had too much of an effect on me during high school when I could have been becoming even better at math.

Wait so is "regroup the ten" basically just carry the one but with a zero on the end? I have no idea what the fuck is going on.

>>8114883
I get the joke, but the fact remains that the second method is easier to apply.

>>8112786
It's really roundabout
Doing it the "normal" way in your head is much faster than taking apart numbers so that they his specific decimal place

>I prefer my good old plug&chug methods wtf is this shit.
Most of those methods are perfectly reasonable. I only see some problems with the ways they are tested but teachers making up unnecessarily conplicatef ways to test knowledge is not common core related

I was about to scoff and call you a faggot but I went back and checked an by God you're right. I never even noticed making that assumption.

why do you think all americans are so fucking stupid m8

shit like this

>>8119082
I'm the guy you're replying to.
just checked again and figured you don't need that assumption, since we have
[math]
A_1 = (12 h_1)/2
[/math]
[math]
A_2 = (12 h_2)/2
[/math]
and with
[math]
h_1+h_2 = 18
[/math]
we get
[math]
A_1+A_2=12\cdot 18/2=108
[/math]
no matter how we choose [math] h_1 [/math] and [math] h_2 [/math]

The 22cm is kind of unnecessary though

>11th Calc 2

So you were able to solve everything related to taylor series, linear algebra, limits, convergence, sequences, fourier transforms, fourier series etc. by the time you were 15 to 16 or does "Calc 2" mean something different here?

>>8119552
These?

>>8112208
the average person in the US will literally never learn derivatives in school. You have to skip a grade to even take calculus one and there isn't much after that
otherwise the average person will end high school learning trig

>>8120050
to further on this, even if you understand math at a high level you will likely end up getting fucked unless you have extremely active parents in your school. I was forced to take courses under my prerequisites for seemingly no reason twice.
