it has good intent, to teach children how to think about math instead of how to regurgitate, but it turns out most kids are just hopeless idiots so it doesn't work at all
it's not common core's fault, it's everyone elses

>>10331586
You can't teach mathematical intuition, so it was doomed to fail by its conception. It isn't good. US education needs to focus on teaching maths (and all subjects in general) in a way that's conducive to children's interests. We've had enough development in the areas of game design to be able to make something that kids enjoy, in regards to education, and it baffles me that it all falls by the wayside.

>jenny has 700 watermelons, if she gives 18% to charity how many melons can she bring home to her jenlets
Fuck this too. Teach them pure math if you'll teach them anything, so it can be applied universally. Otherwise they get to higher math that can't be represented by unusual amounts of food and they flounder, say "we'll never use this uuguggh" because they never developed an appreciation for numbers themselves, only caring about how many watermelon they can buy on one month's assistance and three coupons

Ever since common core has been implemented, this gap between whites and none whites became a chasm.

So you're saying it's taught so nobody has an advantage by being previously exposed to it or have good prior intuition? Sounds like a great way to educate, come up with some completely convoluted way of doing things that no child has seen before that doesn't make sense to them.

>About 31 percent of college-going students who graduated in the spring of 2016 had test scores low enough that required them to enroll in a remedial class when they went to college, the report showed. That rate is double in a handful of the state’s most southern counties.

There doesn't seem to be anything wrong with this. Hell, most of my life I haven't know the basic ten by ten multiplication table. I just turn it into an easier multiplication problem and add any offset.

>>10331692
It's weird to me too. I think there's a lot of room for educational games that don't suck, but it seems like educators/parents (or school admins, or whoever is in charge of paying for things) were only ever interested in things that were really obviously educational.

>>10331826
The intent is good, the execution is awful. Showing multiple ways to think about the same problem is good. Requiring students use specific methods like in that picture is what kills it. And worse the kids can't get help at home, since the parents won't know any of that and the kids are too bored and exhausted to pay enough attention to memorize exactly what they're supposed to do.

Pretty much. 80% of these people went to ghetto schools that have given up on uplift and simply try to make sure that their students don't end up drug addicted criminal wards of the state birthing another generation of drug addicted criminal wards of the state and consider it a runaway success if one of their students goes on to have an unskilled labor job that actually pays taxes. The other 20% are dork-hicks that were home-schooled/from trash rural schools that were completely unprepared for the rigors of college.

Whats really sucks is that the kid is doing the right thing mentally by grouping in 5s. Honestly, I remember arguing similar semantics with one of my teachers in elementary school. In the end her point was as you go through school you won't necessarily become more right but instead less wrong. You learn arbitrarily wrong premises as a stepping stone to learn the less wrong methods later. There is no right method for anything but getting to that point takes time and experience.

but #2 the teacher is correct for matrices anons :^)

The real problem with common core isnt that it focuses on different methods of visualization or even that the teacher requires you to use a specific solution method learned in class. The issue is that it seems to frequently be a replacement for traditional solution methods rather than a supplement.

>>10381266
>The issue is that it seems to frequently be a replacement for traditional solution methods rather than a supplement.


This is the real problem. School time is limited. If a kid is presented with a simple addition problem of say 397 + 165, the basic algorithm to do this as taught in school is to line the numbers up vertically so that each individual digit in the second number lines up with the same 'place' of the digits in the first number. Then add the ones together, "carrying over" any part of the result that "belongs" in the tens spot, to the tens place and add the tens together and "carry over" any part of the result that "belongs" in the hundreds etc. etc. This algorithm always works so it is taught as the basic way to do addition so that students can handle addition of any two numbers by hand if they need to.

Now decently smart kids (probably 120 or 125 iq and up) probably figured out that there was a faster way to do that addition where they could make the 397 a nice round number like 400 which is easy to add in their head with 165, which gives 565, then they just take away the 3 since they added it in the first place and they get 562 the final answer. Lots of common core is aimed at teaching kids these kinds of shortcuts and visualization techniques. The problem is is that the base algorithm is somewhat complicated and kids who are say 100 iq and below need a lot of time and practice on the base algorithm to really master it. And there isn't enough school time to teach them both the new techniques and the basic algorithm. So they wind up never really doing well at either, which when this starts early enough hampers them throughout the rest of their academic career because the new subject is always in part based on what you learned on the old subject. So lots of average and below students become, "Just never was good at math." When they could have been, "Normal or ok at math."

I, in all seriousness, believe high school is a very detrimental institution. Society would improve if it was entirely abolished and not replaced in any way. The idea that teenagers receive anything near an "education" at these internment camps is laughable. Almost everything "taught" in high school top is covered in the first semester of college. If a teenager spends an hour a day doing something modestly intellectually simulating like solving Sudoku, he will not only be qualified to go to college, but will probably be ahead of most high schoolers. It's a nice thought to want to give every child an head-start into the academic world. But it just flagrantly fails. All high school really accomplishes is to waste a teenagers time and to discourage him for pursue a career in science because he understandably learns to view topics like physics and math as painfully tedious and uncool.

common core is a great curriculum guide (and isn't really much more than that). the most publicized stuff is about number sense in the early grades, and desu it's how most "math people" do arithmetic anyway. I think the emphasis on number sense over, say, just the columnar method is good. However, in HS, there are simply too many topics (a) to cover in depth, and (b) for your average student to comprehend w/in the "big picture". They claim that they've tried to reduce topics to allow time for depth, but often this is by "cheating" by simply nominally removing a prerequisite topic from the curriculum that you will really have to teach anyway.

I have the probably unpopular opinion that the required curriculum should actually be quite spare, and the teacher (who should be more educated than most are) should introduce topics as they come up in exploring the core content in depth. CCSS and the upcoming Next Gen standards claim to want to put an emphasis on exploratory learning, having students conjecture and experiment, etc., but for how much content there is and how much remediation is usually needed, this is a farce.

desu i agree w/>>10349818. I am not a fan of prescribed methods, but you have to have some to start playing with them. An nxm matrix is not an mxn, though you can choose either convention depending on how you want to define multiplication. However, it's good to pick one, and then PROVE commutativity, so that the students get a sense of the idea of how a property can be derived from a definition.

If the teacher asked them to use this definition as a toy definition, and the student fucked that up, they might actually be confused about the fact that the statement that "5 groups of 3 and 3 groups of 5 have the same number of elements" is something that can actually be proven.

>>10388197
by "pick one" and "prove commutativity" I meant for standard multiplication, obviously, not matrix.

The financial sector makes markets more efficient, which means pressuring a company's public valuation closer to its true value (once you interpret its business practices, P/L, et cetera). This more-or-less makes it makes sure that investment flows from incompetent businesses (people who don't deserve it) to competent ones (people who do).

There are instances of corruption and exceptions of course, but this is the official synopsis on how the financial industry creates value.

It's funny because since Yukariposter isn't working with a template he picked out, the joke isn't the surrealism he usually works with but a punchline on the end, which works by contrast.
Contrast with pic related and the OP.

It's not meant to be a jump of tens, instead Jack jumps back in one's. However he forgets to do a jump of ten (i.e. he jumps back 306, not 316). The numberline is incorrectly labelled by the parent.

Thanks for explaining it.

Geometry in nature is a kind of math that appeals to both right and left side brain. What children need is to be able to recognize the mathematics of the world around them rather than to simply be calculators.

>>10397247

interesting, but very likely exaggerated, and no way any kid would be doing Calc by 4th grade. Kids that age don't have the inference skills or ability of abstraction needed.

>>10398186

You cannot teach the mathematical intuition gained through 12 years of increasingly difficult work by sudokus, or in one year of college. It's absurd. I won't argue that public schools are perfect, or even that good, but they are not 100% for brainwashing innocent children either.

Thank you for all this Yukari content, I will treasure it.
Also, common core or something.

I thought about common core for a long time over the weekend and decided that in the least an easy fix to many issues would be reduced class sizes. Ever looked through a yearbook from before WWII to see class sizes of 13? Let's compare that to my school career's grand average of 28 per class, absurd, I know. With a higher number of students sharing the attention and guidance of a singular teacher, each student receives less assistance (if needed) on a per-student basis. It is my belief that this reduction in per-student focus causes classes as a whole to suffer not only in the learning of the subject matter, but most importantly in the teaching of proper behavior and conduct in a school (or any) environment. Because so many students can slip through the widening cracks (now breaches: they've widened so) they end up missing bits and pieces of fundamental knowledge and etiquette which feeds into this phenomenon of social ineptitude and educational waning. It seems logical to assume that once classroom behavior is raised to a higher standard with greater accountability (due to more intimate class size) will lead towards more student participation and retention.
I do not think this is the only thing which influences these issues, but I feel it is an important link in the chain which must be recognized and mended to fix the issues.

/sci/ holds an extraordinarily idealist view on this system. Every time this gets posted I imagine the poster is attempting to prove that he is intelligent enough to follow this cirriculum. Lets clarify a few things:
>1. The average student is 100 IQ.
Yep, 100 IQ. The average, which means that these topics are far too complex for them throughout their lifespan.
>2. The average student (pre-adolescence to early adult) is unmotivated.
This should be a no-brainer, but apparenly you all think that it's universal for a student to want to spend their every waking hour on studying. I doubt the average high schooler spends more than 1 hour a day on homework, then spends his entire school day on socializing (skills /sci/ lacks). Even intelligent kids who would qualify for this program would fail. It takes study time to understand advanced topics - the complexity of mathematics tends to grow on an exponential curve, and the students who breezed through trig functions will find themselves lost in multivariable calculus, finding that they lack both the intelligence to comprehend it in mere minutes and the motivation to spend hours comprehending it.
>3. This costs money.
This absurd cirriculum with obtusely complex math courses and strangely simple programming classes would be enjoyed by about 1 out of 10,000 students (source: basic human approximation). About 10 out of 10,000 students would attempt to join it, with 9 realizing they wanted the prestige but did not want to put in the effort. If your parents had money, I'm sure they could afford a private tutor to free you from the clutches of a standardized public school system and hopefully help you understand why this post is stupid.

Not favorable. I taught my baby sister how to transact money and the damn class has been doing it for one month and still gets the answers wrong. Also they want her to do some project on Anne Frank and how it relates to equality and democracy. She's barely cognizant that she has deadlines for homework.

We don't have Common Core in Britain. What's the premise behind it's institution? What does it change?
