Good intentions, retarded execution. Yes we should teach kids to think and abstract with maths, not only crunch numbers. But teaching kids to abstract arithmetic ina different way is fucking retarded when the problem is with the curriculum itself.
Stop with this pragmatic obsession of mathematics and start showing what mathematicians actually do. Make mathematics an enjoyable and engaging class with basic proofs, challenges, interesting theorems and a constructivist approach to math. Literally start with the Greeks and go building many subjects until calculus.
>>7638187 It's teaching children that there is a difference between both ways, i.e. that commutativity isn't a thing. There's no reason to not get the basics right the first time, and many reasons why instilling false ideas is terrible.
>>7638332 When I was a kid it always was taught >A times B So B, A number of times.
You can switch it around and get the same outcome, but that still makes it a different equation. This doesn't matter when the only thing you need is the answer. It does matter when how you got there is also required.
>>7637792 when I learned addition and multiplications at school, on add/mult tables, I had to put a fucking arrow that shows "it's 6*4 and no 4*6"... like if it wasn't commutative, and some other silly things
but op's exemple is even worse, proving the common core's stupidity
>>7637892 Not really, how many kids at highschool get statistics becasue "its useful in life". Later on they will forget nearly everything they saw because statistics requires more than a shitty one year course. I mean, go with any adult and ask them to optimize their fence space with basic calculus and they will be perplexed with the task. Basically, we are obsessed into convincing kids that math is useful so you should learn it while in the real world it may not be precisely that. Yes, everyone should know basic arithmetic, geomtry, stats and some algebra for day to day tasks. I mean, knowing how a percentage works is fucking required in today's work, butif we mix it with logs, boring trigonometry classes and pointless calculus, most people will end up giving up math in general and leave 25% tips.
If we create a math culture were people appreciate the complexity and depth of math and also its beauty, more people will tend to learn interesting things about math and embrace the subject.
>>7637876 >Good intentions No the intentions are evil, just like every other leftist agenda of the last 100 years This is 100% political, made around closing the achievement gaps for blacks by having a stupid cirriculum.
I'm relearning trig with tau and loving to put the pi in its place. The geometric sense of "hmm, 7/12 tau is a bit over another half-turn" makes so much sense I would kiss the guy who thought it if I could.
>>7638606 but with tau is easier to imagine than half of it, that's the point. whole circles, half circles, one notation.
if you've already doctrined with pi I understand your stubborness, it's kinda natural, even PhDs react childishly when a stone 'truth' they memorized eons ago is 'attacked', i saw and surprised myself with the fact.
say, do you count miles in halves too? after all it's just a factor of two, right? only imbeciles have trouble with that, right? they should quit the damn thing altogether...
nope, I'm gonna push forward until one of you loonies try to stop me with your stuttering discourses of "you should quit because your dumb" and then i'll trample the fucking out of you with taus
>>7638698 apples and oranges. I like the way of thinking, can convert to pi if needed but the geometrical insight is brilliant. I mean really, why didn't Euler thought it first? >>7638703 I thought we were talking about stupid ways of teaching basic skils? I think trig was stupid and completely absurd before I learnt the tau thing.
Then I got interested in that again, I ws about to give up to rote memorization but now it clicks, you know? I think it is a good thing. In the tau for trig site at least a teacher got some nice results too, nothing extremely successful but useful.
>>7638708 Well is the fact that you got "interested" in trig by such a meaningless concept. Im talking abour changing the whole curriculum into a more historical and constructivist math. Nort just changing Tau to pi or that shit to other shit etc. That's what common core is doing which I find retarded.
Even if today you say oooo this was much lore easier than what my teacher told me, people who learn this easier methods still wil suffer evry single math class they are in.
>>7637876 >elementary school kids who already hate math >most will never go to college >make math even more useless and less relevant to their lives They would be better off teaching kids calculations relevant to their everyday lives so that they enjoy math and appreciate its useful qualities, making them want to study it more. Have them apply what they learn to calculating damage for pokemon cards, or whatever the hell kids that age do for fun these days.
>>7638021 r x c. there should be 4 rows and 3 columns.
I think this is a syntactical issue more than anything. If you're teaching kids the order of the multiplication doesn't matter, then they aren't understanding the underlying concept of how multiplication actually. Essentially if I have x and I multiply by y, then the notion of a dimension has been added. I have x and each x has y.
Ultimately the reason why it's fundamental and important is because multiplication is used in highly technical fields, ones that can't afford confusing x and y. If we have a common exam testing the underlying concepts only a small percent will be correct and those are the ones qualified to do the job.
>>7637792 I found with math in school that it never grabbed my attention. I think it should be at least a quarter history of whatever math you are learning. Like with geometry. If they had given a little backround to the greeks and why and how they originated their formulas. I would have been waaay more engaged. Also, making people show work is fucking dumb. Let the ones who need to show work do it. And leave the ones who don't alone.
